Pretty pedestrian given the others, but I'm trying to build a file server setup that makes it easy to roll back from a ransomware (encryption) attack. I starting to think that going with hourly syncs from the home directory with some versioning should do it. The hard part is to make it easy for someone to rollback when I'm not here. People are a bit scared given that its happened to a couple of other small colleges. We already do tapes and we are talking files saved to the servers (most folks aren't allowed to save locally), so it should be within a budget. Like I said, pretty pedestrian. [edit: FreeBSD & ZFS]
