I've seen bit-rot on a few disks out of hundreds used over the last 35-ish years.I am now storing /var/lib/backuppc on a ZFS RAID since the last catastophic disk failure. Sure enough one of those disks started writing garbage and then was taken off-line through infant mortality. The pool kept going. A year or so later a different disk went off-line, with a dying SATA cable this time. The pool kept going. In both cases rebuilding the array ("re-silvering") happened automagically. Very happy with ZFS myself. YMMV.
Curious i have ZFS on my backuppc4 machines and i got horrible performances. /usr/share/backuppc/bin/BackupPC_refCountUpdate is completly killing the machine for hours while on btrfs and ext4 it does not cause any issue. i am planning to move out of ZFS as soon as i can because notaime, nosync and all optimisation like l2arc on ssd have not helped the problem :( -- cordialement, Ghislain _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
