Linux, but it's pretty hard to do encrypted *and* deduplicated backups without dedicated software. Encryption breaks lower-layer (e.g. btrfs) deduplication.
Encryption is valuable because the backups are stored in a bank vault, which could be robbed or something.
Deduplication is valuable because that makes it possible to keep backups going back several years without running out of disk space on the backup drives.

yeah- thats a bit tough. hehe, you could just move to tape LTO 6/8 - its rather unlikely for a lowly robber to extract LTO tapes. Especially if you are just doing block, hit that shit with LUKS- and write the encrypted blocks to tape. plus, tape tends to last a rather long time :) Cheers -nate
