a
wealth of trouble. You shouldn't need a whole lot of fancy features
like
snapshotting, copy-on-write, deduplication etc. on your pool anyways.
I think I'm down to XFS vs ext4. Are there any strong advantages of
either for use as a BackupPC pool?
For what it's worth, I don't recommend XFS. I used XFS for quite a
while specifically with BackupPC, and the problem was fairly subtle
corruption that XFS could not recover from.
I also disagree that one doesn't need copy-on-write. Presumably, you
want your backups to be reliable, and not implode at the first power
failure?
On the other hand, I've heavily used btrfs, and I'm with Kosowsky, it's
absolutely rock solid. I wouldn't recommend its RAID5 or 6
implementations, but it's proven to be excellent in a mirror or singles.
If you're using Red Hat, you might want to go with ext4, otherwise,
btrfs or ext4 are excellent choices. xfs isn't.
