- Failure to access HPSS
- Failure of HPSS tapes
- Simultaneous failure in both locations is possible (nuclear war)
- Fire, tornado, or other catastrophic failure in WCC machine room
- Disgruntled employee attempts to delete everything from HPSS
- Disgruntled employee attempts to delelte random sets of items from HPSS
- We need a system to provide periodic reports on the existence of orphaned and incomplete objects, so we can keep the contents of the repository "clean".
- Eventually, we would like to set up a "digital preservation advisory board" to proof our decisions. This page and its children will eventually be maintained by the board.
- Can we eventually store lots of small files (page images) directly in HPSS via the filesystem interface without aggregation, or will it simply take too long to retrieve these files?
- Should we store copies of our metadata in HPSS, or are the regular server backups good enough for this?
- How do we manage preservation packages for materials that will be accessed through Variations? We don't want to store duplicate copies of the derivative files, because they are quite large. Perhaps Fedora can store these as Redirect datastreams, and just keep the appropriate metadata in the actual repository directories.
