Also, I find btrfs snapshots to be very valuable. Especially, if I am messing/playing around with backuppc... that way I can easily revert if I mess something up... Snapshots have also saved me when I have run across the occasional backuppc gremlin of disappearing files in that I can find the cpool file and revert it from past snapshots. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
