Digital preservation the hard way
Metadata[+] Show full item record
An awesome tool set for digital preservation is available to all institutions who use DSpace. This is not a story of how we used this tool set. This is a story of how we recovered from an accidental deletion of a significant number of items, collections, and communities--an entire campus's ETDs: 315 missing items, 878 missing bitstreams, 1.4GB of data, 7 missing communities, 11 missing collections--using a database snapshot and a tape backup. The SQL we developed to facilitate this restoration may be helpful, but it is our hope that in comparison, the effort required to implement a proper backup and preservation safeguard, such as DuraCloud and/or the Replication Task Suite, will rightly seem more appealing. In other words: here's how to do it the wrong way, but you'd really be better off doing things the right way. This poster should be sufficient to serve as a guide for actually recovering from an accidental deletion of materials in DSpace, if one only has a database snapshot and a tape backup of a DSpace assetstore. It will also serve as a reminder of the digital preservation tool set available for DSpace, as well as why these tools exist.
