Typically, Jason Scott was first to respond with a outline proposal to back up the Internet Archive, by greatly expanding the collaborative efforts of ArchiveTeam. I think Jason is trying to do something really important, and extremely difficult.
The Internet Archive's collection is currently around 15PB. It has doubled in size in about 30 months. Suppose it takes another 30 months to develop and deploy a solution at scale. We're talking crowd-sourcing a distributed backup of at least 30PB growing at least 3PB/year.
To get some idea of what this means, suppose we wanted to use Amazon's Glacier. This is, after all, exactly the kind of application Glacier is targeted at. As I predicted shortly after Glacier launched, Amazon has stuck with the 1c/GB/mo price. So in 2017 we'd be paying Amazon $3.6M a year just for the storage costs. Alternately, suppose we used Backblaze's Storage Pod 4.5 at their current price of about 5c/GB, for each copy we'd have paid $1.5M in hardware cost and be adding $150K worth per year. This ignores running costs and RAID overhead.
It will be very hard to crowd-source resources on this scale, which is why I say this is the opposite of Lots Of Copies Keep Stuff Safe. The system is going to be short of storage; the goal of a backup for the Internet Archive must be the maximum of reliability for the minimum of storage.
Nevertheless, I believe it would be well worth trying some version of his proposal and I'm happy to help any way I can. Below the fold, my comments on the design of such a system.
ReliabilityWhy is reliability so important for this system? After all, I've been arguing that reliability isn't as important as people think elsewhere. Lets suppose that somehow we have a single copy of the 30PB on disks, and that we perform an integrity check via checksums 10 times a year. Optimistically, we assume these disks never fail for any reason, but they achieve their specified Unrecoverable Bit Error Rate (UBER) of 10-15. There are 2.4*1017 bits in the copy, so on average every time we do an integrity check we will get 240 bad bits. Pessimistically, we assume these bits are randomly distributed (this makes the analysis much easier).
If, as Jason suggests, the backup is divided into 70K 500GB blocks, the probability that any of them will have more than 1 bad bit is small, so we will lose 10*240*500GB of data every year, or 1.2PB, or about a third of the incoming data. Of course, we can repair these failures from the Internet Archive itself, at the cost of increasing the bandwidth impact from about an additional quarter of the Archive's current bandwidth to about a third (see below). But the probability that the Archive and the backup would lose the same data becomes significant.
This argues for much smaller blocks, to reduce the impact of the UBER at the cost of increasing the overhead of the system. Smaller blocks would also make it possible for more people to contribute storage, both from the cost of their contribution and from the impact on their bandwidth. Downloading 500GB on my DSL link would take its entire capacity for two weeks.
In real life, even in data centers disks fail in all sorts of ways that make UBER fairly unimportant. The crowd-sourced disks are likely to be much less reliable still. So the system needs to replicate the data.
ReplicationThe discussions I've seen so far assume that the data is simply replicated, as it is in the LOCKSS system, but only three times. Even replicating by a factor of three means the demand for storage in the backup network by 2018 is nearly 100PB. Clearly, some scheme that gave adequate reliability but used less storage would help significantly. There are two techniques that might help, erasure coding and entanglement. Warning: the following discussion is radically simplified, see here.
Erasure CodingErasure coding is like a distributed version of RAID; files are divided into storage blocks. These data blocks are organized into groups of N. For each group (M>N) blocks are stored, containing the data from the N blocks mixed together so that from any N blocks in the group the original data can be recovered. This allows for non-integer replication factors; the replication factor is (M/N). There are two ways to do this:
- The N data blocks can be stored unchanged, and (M-N) parity blocks computed from the N blocks can be added. This is the way RAID typically works; it has the advantage that, if nothing has gone wrong, reading a data block requires accessing only a single block. Writing a data block requires writing (1+M-N) blocks, as the parity blocks need to be updated to reflect the new data.
- The N data blocks are not stored. Instead M blocks are stored each computed from all of the N data blocks in the group. Reading a block requires accessing N blocks, writing a data block requires accessing M blocks.
The real importance is that no individual storage node can, if compromised, reveal any data. In the context of a crowd-sourced backup of the Internet Archive, this is important. If a node in the backup network contains data from the Archive "in the clear" the owner of the node might be in trouble if the relevant authorities considered that content undesirable. If the owner has deniability, in the sense that they can say "there is no way I can know what the data I am storing is, and no way anyone can recover usable data from my disk alone" it is much harder for the authorities to claim that the owner is doing something bad.
The second form of erasure coding has desirable properties for a backup of the Archive, and it can significantly reduce the demand for storage. Examples of systems using the second form of erasure coding are Tahoe-LAFS and Cleversafe.
EntanglementEntanglement was introduced in two 2001 papers, Tangler: A Censorship-Resistant Publishing System Based On Document Entanglements by Marc Waldman and David Mazières, and Dagster: Censorship-Resistant Publishing Without Replication by Adam Stubblefield and Dan Wallach. It has recently been revived in a strengthened form by Verónica Estrada Galiñanes and Pascal Felber in their paper Helical Entanglement Codes: An Efficient Approach for Designing Robust Distributed Storage Systems.
Like the second form of erasure coding, entanglement does not store the data blocks themselves. Each stored block contains data derived from multiple data blocks. The key difference is that erasure coding mixes the data from a fixed group of blocks, whereas entanglement does not organize the blocks into groups but mixes each incoming block with a pseudo-randomly chosen set of stored blocks. This has the following effects:
- Since the information from which a data block can be recovered is spread across the whole set of stored blocks, deleting or over-writing a data block will affect other data blocks. If the spread is wide enough, selective censorship is effectively blocked and the system is append-only. For the Internet Archive backup application, this is a good thing.
- Entanglement supports only integer replication factors:
- Tangler's publishing algorithm takes two stored blocks and a data block and outputs two new stored blocks, thus its replication factor is two. A data block can be recovered from any three of the four (two input and two output) stored blocks.
- In the default three-strand configuration of the Helical Entanglement Code (HEC) system publishing takes three stored blocks, one from each strand, and a data block and outputs three new stored blocks, one for each strand. Its replication factor is thus three. Absent data loss, recovering a data block requires accessing two successive stored blocks from any of the three strands. If data loss means that none of the three strands can supply the necessary blocks, a search process can recover the lost stored blocks from information in other stored blocks.
- A system provides document dependency if a document cannot be recovered if any document it is entangled with is lost.
- A system provides all-or-nothing integrity if no document can be recovered if any document is lost.
Entanglement has several desirable properties for a backup of the Archive, but it has too high a replication factor to be practical.
RequirementsIf I were doing the design I would start from the end I haven't seen any discussion of so far. Its neat to have a backup copy of the archive, but if it won't actually work when it is needed what's the point? So I'd start the design by looking not at how the data gets out there, but at the use cases when the data needs to get back. Two obvious cases are:
- The archive loses say 10TB, perhaps because it suffers a rash of correlated disk failures. How does the archive get it back from the backup?
- The Big One hits the Bay Area and the entire archive is lost. How can the service be re-constituted from the backup?
Once I had a good recovery design, then I'd figure out:
- How to get data from the archive into a system like that.
- How to continually audit the system verify that it was in good enough shape to work when needed, something systems used only in an emergency frequently fail to do.
- Capacity of 35PB by late 2017.
- Replication factor less than 1.5, to limit storage demand by late 2017 to less than about 50PB, or say 100K volunteers each providing 500GB.
- Provides deniability (see above).
- Ingest bandwidth of 15PB/year by late 2017 (the current content of the archive needs to be backed up in say 2 years while it is growing say 5PB/year). Note that this is about 4Gb/s leaving the archive, or roughly an additional 25% outbound bandwidth.
- 95% probability of correctly recovering 10TB in 5 days (it is assumed that much of the content will be off-line most of the time, so instant recovery cannot be a requirement).
- 95% probability of correctly recovering 95% of the entire archive in 90 days.
- Meet these requirements in the face of 5% malign nodes conspiring with each other, and realistic error and availability probabilities for the non-malign nodes.
- The system self-configures as available storage resources change so as to:
- Ensure all content is stored.
- Minimize the variation of replication factor across the content.

The following is a guest post by Barrie Howard, IT Project Manager at the Library of Congress.
This interview is part of a series about digital preservation training inspired by the Library’s Digital Preservation Outreach & Education (DPOE) Program. Today’s interview is with Sam Meister, University of Montana-Missoula, who is a DPOE Train-the-Trainer Workshop instructor and is also an instructor for the Society of American Archivists Digital Archives Specialist (DAS) Curriculum and Certificate Program.
Barrie: Sam, you attended the inaugural DPOE Train-the-Trainer Workshop in Washington, DC, correct? Can you tell the readers about your experience and how you and others have benefited as a result?
Sam: I was fortunate to have had the opportunity to participate in the inaugural DPOE Train-the-trainer workshop in September 2011, very soon after I began my position as Digital Archivist at the University of Montana. This was a very valuable and timely opportunity as the experience kick-started my thinking and practice around digital preservation in the context of my new institutional setting.
When I recall the experience of those two days in September I think of a group of professionals who were excited and energized, eager to learn how they could play a role in sharing and building community of digital preservation knowledge around the United States. While some of us were coming to the workshop with less professional experience than others there was a feeling of collaboration and mutual benefit and respect amongst all of the participants. Additionally, we had an amazing opportunity to learn directly from leading experts and practitioners in the digital preservation field. The two workshop days were filled with exercises, conversations and debate, and by the end I felt ready to return to my corner of the country and share my new knowledge and skills with others in my region.
I feel I have benefited from my experience in a few different ways. Through workshops sponsored by the Montana Historical Society I have been able to present the DPOE curriculum to representatives from multiple cultural heritage organizations around the state of Montana. The workshop opportunities provided an opportunity to better understand the particular needs and concerns of smaller institutions, grounding and solidifying the importance of educational materials such as DPOE to encourage and empower individuals to take some action now, even if small. Additionally, I believe that education is integral to the sustainability of digital preservation, whether that is at a small historical society or a national digital preservation network. The DPOE experience has provided me with a set of materials and approaches to continue to further my own educational activities in the digital preservation arena.
Barrie: Since becoming an official DPOE Trainer, you’ve taught SAA DAS courses and helped revise the DPOE Workshop Curriculum. Did your DPOE training inform the development of the SAA DAS course(s) you teach?
Sam: Yes, my DPOE training definitely informed my approach to teaching in the SAA DAS program. There is some crossover in the type of audience, made up of professionals who have been in the field, but may be in the beginning stages of developing and implementing local solutions for the long-term management of digital content. In that way, I have drawn from my experiences teaching DPOE workshops and applied this in the SAA DAS settings.
I would say that the approaches I have utilized have more to do with form and structure rather than the course content itself. In a one- to two-day workshop setting with around 20 people there is an opportunity to find a balance between presenting the course content and making room for a more conversational atmosphere. I have found that workshop participants desire real-world examples of the concepts that they are learning about, so I attempt to ground the course materials in my own experiences as a digital archivist. This may sometimes lead to slightly tangential conversations, but often these end up being very valuable to attendees.
Some of the desired outcomes for either the DPOE program or the SAA DAS courses are to instill in the participants the skills, knowledge and confidence to return to their institutions and start doing something, even if small, to tackle the digital preservation challenges they face. Learning about how others have dealt with similar situations helps to strengthen and build this confidence.
Barrie: Have you developed any other training materials from the DPOE Curriculum?
Sam: I have started developing a set of training materials drawing from the DPOE Curriculum that could be utilized in a workshop or training event on personal digital archiving. I’m in the early stages of developing these materials, but am excited about the potential of the DPOE Curriculum applying to this type of audience.
Barrie: Regarding training opportunities, what do you think are the strengths and challenges of traditional in-person learning environments versus distance learning options?
Sam: To date, I have only presented training opportunities for in-person settings, so I can speak to my experience as instructor in that regard. As a student, I have had experiences with both traditional and distance learning environments. Drawing on my experience as both an instructor and a student I would say that one of the challenges in a distance learning setting is creating an environment for meaningful exchange and dialogue between the students and instructor and amongst the students themselves.
While digital preservation as a subject may not be post-structuralism or philosophy, I have found that the opportunities for direct and immediate exchange, whether as an entire group, small groups, or as pairs, clearly benefit students by allowing for a deeper engagement with new, unfamiliar and seemingly abstract concepts. As an instructor, I know what parts of the course content may be difficult, and I can sense via body language or facial expressions if I need to spend additional time on a particular section to clarify. Additionally, as an audience that is primarily practicing professionals, the sense of community and support that results from attendance at in-person workshops is a very valuable outcome that will be of assistance well after they return to their particular institutions.
That said, digital preservation is a global challenge, and distance learning technology is steadily advancing to improve the experience of both instructors and students. While at this time we may not be able to fully replicate the in-person setting in an online environment, we should continue to make any and all efforts to expand the knowledge and skills needed to develop sustainable digital preservation solutions around the globe.
Barrie: What are your plans as a digital preservation training instructor for 2015?
Sam: I’m looking forward to an initial opportunity to participate as a instructor in a train-the-trainer workshop sometime in 2015 to help educate a new set of trainers to expand the digital preservation education network even further.
The strike at York University, where I work, enters its fourth week tomorrow.
The university’s Labour Disruption Update site (they are always very careful to call it a “labour disruption”, not a strike) has some information for people in CUPE 3903 Units 1 (TAs) and 3 (GAs) who want to come back to work. If you follow through and log in with your York account, this is what you get.“By clicking this checkbox, I agree that I am resuming all of my work assignments.”
It’s sad to see York University, home to decades of progressive thinking and social activism, doing this.
DuraSpace News: REGISTER for the 2015 Texas Conference on Digital Libraries–Early Bird Discount Ends March 31!
From Kristi Park, Interim Director and Marketing Manager, Texas Digital Library
Jonathan Markow, DuraSpace CSO, speaking at the DuraSpace Summit where members gathered on March 11-12, 2015
It has been some time since we hosted our Digitization Matters symposium, which led to our report, Shifting Gears. This event and findings from the surveys of archives and special collections in the US and Canada, and the UK and Ireland have helped to shape our work in the OCLC Research Library Partnership for some time. However, we felt like enough time had gone by, and enough had changed that it was time for us to begin some new discussions in order to frame future work.
We often hear from library colleagues that they continue to experience challenges associated with digitization of collections, so earlier this month we hosted some discussions (via WebEx) to try to get a handle on what some of those challenges are. Prior to the conversations, we asked participants to characterize their digitization challenges, and then did some rough analysis on the responses. Challenges fell into a number of areas.
- Rights issues (copyright, privacy)
- Born Digital, web harvesting
- Issues with digital asset management systems (DAMS) or institutional repositories (IR)
- Storage and preservation
- Metadata: Item-level description vs collection descriptions
- Process management / workflow / shift from projects to programs
- Selection – prioritizing users over curators and funders
- Audio/Visual materials
- Access: are we putting things where scholars can find them?
We opted not to include the first four issues in our initial discussion — copyright, and rights issues in general, are quite complicated (and with a group that includes people from Canada, Europe, Asia, Australia, and New Zealand I’m not sure we could address it well). We have done quite a bit of work on born digital (and are currently investigating some areas related to web harvesting). At least for our first foray, discussions on DAMS and IRs seemed like they could have gone down a very tool-specific path. Likewise with storage and preservation. Even taking these juicy topics off the table, we still found we had plenty to chew on.
Metadata: Item-level description vs collection descriptions
Many of our discussion participants are digitizing archival collections — there is an inherent challenge in digitizing collections at the item or page level when the bulk of the description is at a collection level. People described “resistance” to costly item level description, and a desire to find an “adequate” aggregate description. On the other hand, there was an acknowledgement of the tension between keeping costs down and satisfying users who may have different expectations. A key here may be a more nuanced view of context — for correspondence, an archival approach may be fine. In other circumstances, not. Some institutions are digitizing collections (such as papyri) where the ability to describe the items is not resident in the library. How can we engage scholars to help us with this part of our work?
Process management / workflow / shift from projects to programs
Many institutions are still very much in project mode, looking to transition to programs. For those who have or are working towards digitization programs, there is a struggle to get stakeholders all on the same page: at some institutions, the content owners, metadata production unit, and technical teams seldom if ever come together; here, getting all parties together to establish shared expectations is essential. Some institutions are looking to establish workflows that will more effectively allow them to leverage patron-driven requests, while others are thinking about the implications of contributing content to aggregators like DPLA. One institution has started scanning with student employees — when students have a few minutes here or there, they can sit down at a scanning station and scan for 10-15 minutes — this leads to a steady stream of content.
Selection – prioritizing users over curators and funders
Many institutions are still operating under a model whereby curators or subject librarians feed the selection pool, either through a formal or informal process. Even in these models, it can be difficult to get input from all — there tend to be a small pool of people who engage in the process. At one institution, people who come with a digitization request are also asked to serve as “champions” and are expected to bring something to the project — contributing student hours to enhance metadata, for example. One institutions views selection as coming through three streams — donor initiated, vendor or commercial partner initiated, and initiated by the curatorial group (emphasizing that the three are not mutually exclusive). Another institution is looking at analytics and finding that curator initiated requests generate less online traffic than patron initiated requests. In a similar vein, a third institution is looking at what is being used in the reading room and considering making digitization requests based on that information. Even though people’s survey responses indicated that they would like to move selection more towards directly serving researchers needs, from the discussion I’d observe that few institutions have established models to do so.
As with born digital, everyone has A/V materials in their collection, and making them more accessible is a concern. A participant from one institution observed that they see key differences in interest for these formats — for example, filmmakers, not scholars, are the people who will seek out video. If there is a transcript for materials, that may impact demand. A/V projects tend to focus on at-risk materials, since costs are so high. Some institutions are beefing up their reformatting capacities, in anticipation of needing to act on these materials. If you are interested in this area, you will want to track the activities of the (US based) Federal Agencies Audio-Visual Working Group.
Access: are we putting things where scholars can find them
For many institutions, aggregation is the name of the game, and thinking as a community about aggregating content is key: “Standalone silos don’t help users find our things.” Whether materials are in discovery repositories that are hosted by the institution or elsewhere, discoverability and user experience are concerns. One institution assigns students to search for materials via Google and in repositories. Are collections findable?
Thanks to all who took part in our discussions! I hope we’ll have more to report in the future.

My first post on UXLibs was bits taken from my conference notes. This is what shook out when I reread all my notes and reflected a bit.
Matthew Reidsma (who was somehow even more inspiring in person than online, and I’m not sure how that’s even possible) spoke in his keynote about Heidegger, including his concept of being-in-the-world, and the question “How does the world reveal itself to us through our encounters with it?” In my notes, I continued “How does the library reveal itself through our encounters with it?” and – more pertinent to my work – “How does the library website reveal itself through our encounters with it?” Matt went on to explain that by interacting with things, we are making meaning. So, by interacting with the library website, what meaning are we helping our students make?
This made me think of the great workshop I’d had with Andrew Asher on the first day. One of the many things we did was watch videos of students trying to find information. A second year student needed to find peer reviewed articles but clearly had no idea what this meant. A fourth year student came upon an article on her topic from the Wall Street Journal and thought it could be useful in her paper because it sounded like it was on her topic and came from a credible source (not seeming to realize that a credible source is not the same as a scholarly source). I found it striking that neither of these students seemed to understand what scholarship looked like; what it meant for a thing to be a scholarly source.
So, taking those two points together, is there a way we can help students make meaning of scholarship through interacting with our website? And I don’t just mean, how can we help them understand how to find various scholarly materials (you find books in this way, you find journal articles in that way), but can we help them understand how to interact with a journal article in a scholarly context? Can we help them use that article to first create understanding and then create their own scholarly work?
This in turn circles back to Donna Lanclos’ keynote on the first day where she challenged us to move beyond helping our users with wayfinding, and engage with them in the act of creation. She challenged us to move beyond the model of the bodiless scholar whose chair is hard, who can’t leave the library to eat, and who has to endure horrible searching on crappy library websites to find what they need. The finding part doesn’t have to be so hard. The hard part should be thinking about what you’ve found and then making something new out of it.
So, to grab a phrase from Paul-Jervis Heath’s keynote, “how might we” design a library website that helps students make meaning out of the scholarship they are finding? How might we design a library website that helps students focus less on finding and more on thinking and creating?
Since reading Emma Coonan’s great piece in UKSG News, “The ‘F’ word,” about moving away from a focus on finding in the context of information literacy, I’ve been wondering how we could do this in the context of the library website. UXLibs has prodded me further, and – even better – given me some tools, techniques, and a giant mound of inspiration to get out and try to start working on it.
Today I found the following resources and bookmarked them on Delicious.

The DPLA family was devastated to hear that one of our Community Reps, Sabra Statham, passed away suddenly on Friday. Sabra was a Digital Project Coordinator at Pennsylvania State University and had joined the Reps program in 2014 as part of the second class. In the last year, she worked enthusiastically to represent DPLA in conversation with local Pennsylvania genealogy groups and in collaboration with her fellow Pennsylvania reps. She was multitalented: in addition to her innovative work in the library at Penn State, she was an accomplished musician and a scholar of musical modernism.
On a personal note, I met Sabra when I visited Penn State last year, and was enormously impressed with her and her many projects. She cared deeply about reaching a broader audience through digital means, and worked on many fronts toward that goal, including through DPLA.
Recently Sabra was selected to receive a 2015 DPLA + DLF Cross-Pollinator Travel Grant to attend DPLAfest 2015. It’s hard for all of us to understand that she won’t be joining us in Indianapolis next month.
Our thoughts and prayers are with Sabra’s family and friends.
DPLA: National Endowment for the Humanities announces award to support expansion of DPLA Hub network
The National Endowment for the Humanities awarded $250,000 to the Digital Public Library of America today, in support of DPLA’s effort to continue to build its network of Service Hubs across the United States. The funds will be used to help cover states that currently do not have an on-ramp, through a state or regional digital library, for their collections to get into DPLA’s national, open collection. The award is being made as part of NEH’s new Common Good initiative, which is highlighting and demonstrating the importance of the humanities to the general public.
“We see our mission of bringing the riches of America’s libraries, archives, and museums to everyone as in great harmony with Chairman Adams’ Common Good initiative,” said Dan Cohen, DPLA’s Executive Director. “We deeply appreciate receiving this funding under that banner, and look forward to working with NEH and its other grantees to connect the public with the works of the humanities for years to come.”
The National Endowment for the Humanities has been a major supporter of DPLA from its inception. Today’s grant supplements the $1,000,000 that NEH provided to help launch DPLA in April 2013.
“These supplemental funds from NEH will allow us to continue to grow the map by supporting DPLA’s efforts to assist in the development of new state and regional based Service Hubs,” said Emily Gore, DPLA Director for Content. “The increase in hubs will allow us to come closer to reaching our goal of having an on-ramp to DPLA for all interested cultural heritage institutions in the US.”
The NEH’s official announcement can be found here.

Time to take another tour of the edges of Islandora, where work is being done in the community on tools and modules that you can use (or help to build!) to make your Islandora better. Previous iterations of this blog have featured modules that long since became part of the Islandora release stack, and we hope that some of today's featured modules will also make that journey someday:
The Manuscript Solution Pack, developed by discoverygarden, is an important step forward for digital humanities support in Islandora, allowing users to create and view manuscripts with the upload of TEI and XSLT and CSS documents.
Users will be able to view transformed manuscript TEI (via the upload XSLT) side by side with the image(s) of the manuscript (via the Open Seadragon viewer), and browse all of this via Box / Folder hierarchies as defined by their record in an associated finding aid, such as EAD.
This module is explicitly a work in progress and not ready for use, but when it is finished it will allow a user to ingest database dumps (.SQL files) as Islandora objects that are then spun up into live, browsable (read-only) database instances using Docker and Adminer.
This module is being developed by Ashok Modi of Cherry Hill to support a project where fedora objects that were in Islandora 6.x had to be moved over to to Islandora 7.x and into new content models. To use it, you give it credentials for to the islandora 6.x site, provide a PID, and that object can be copied over to Islandora 7.x.
Tuque connects to the remote repo, gets the object and its datastreams, and maps them to the appropriate 7.x solution pack content model to bring over.
There are still some bugs to work out and an ongoing discussion here on the listserv if you want to know more.
The brainchild of discoverygarden's Dan Aitken (you may know him as QADan), this module adds two new fieldsets to collection management pages, to handle derivatives on one object or many objects at once. The first allows a user to generate or regenerate any and all available derivative datastreams on selected or all objects in a collection. The second allows a user to regenerate the DC datastream for selected or all objects in a collection.
Our last Long Tail module comes from Donald Moses at UPEI. Islandora Taxonomy Autocompletes works with Drupal taxonomies and Islandora XML Form Builder form fields to bundle up some authority driven autocomplete options for your MODS metadata.
