Virtualisation can help a lot. The ability to snapshot a server version
along with the data it analysed is probably the right approach (and a
relatively small footprint, since if you are doing it right, you are taking
But you still have to set it up...
Research data is interesting. Massive volumes, relatively short "live" time
frame before it can be migrated to slower storage. Tiered storage solution
help a lot. Archiving to tape is viable but really need a way for it to be
automatically accessed (by users without sysadmin involvement - less work,
more likely to be used, and users test the archiving validity constantly...
