I have a FreeBSD server in my home office that has a big ZFS raidz volume that I use for shared file storage, and it's really, really awesome. The snapshots are especially great because they greatly reduce the fear of screwing something up. I once wanted to run a de-dupe script on several hundred gigabytes of photos, but I was afraid it would go awry, so I snapshotted first, knowing I could roll back in a few keystrokes. (Granted, this wouldn't help much if the script had caused some problem that wasn't immediately apparent. And yes, I have backups of all of that stuff elsewhere, but doing a restore from backup is a lot more work than rolling back a snapshot.)
