The Sun E450 and E4500s I used to deal with had Legato NetWorker as =
"enterprise backup solution", which I think is now owned by EMC / Dell.

It was somewhat smarter than doing a Unix filesystem level dump/restore.
In particular, it understood a bunch of common filetypes and implemented
delta archiving for mbox files and the like rather than having to =
entire copies of changed files.
