Would someone care to either remind me > what the issue was, or reassure me that it's been rectified? btrfs has a limit on the number of hardlinks that can exist in the same directory. I don't believe that BackupPC will create any more hardlinks in a given directory than are already in the filesystem you are backing up. It uses hardlinks between directories for files that haven't changed. David
