Not everybody experiences it, and I don't know what conditions trigger it, but I've seen it at multiple sites with different setups.Īs for SuperDuper, I've heard only good things about it. This bug has persisted across at least 3 paid upgrades now. For disk-based backups this is not too bad since it just takes time for tape you get to feed in all the tapes in the set so it can read them. But it also has a nasty tendency to corrupt its catalog files, forcing you to run a "repair" operation on you backups. Retrospect will compress the data to save drive space, and it allows you to restore via a date of your choice.

Any interruption in any backup and it will leave things in a state where manual cleanup and starting the backup over from scratch is required. Rdiff-backup creates and maintains a copy of not only the current data but also keeps reverse diffs so you can recover old versions too. If you don't mind resetting creation and modification times of every file (not just changed ones) on the backup every time you backup.
On OS X, rsync -E will copy resource forks and extended attributes. Users/*/Librar y /Caches The only 'issue' is that I don't seem to be able to boot from the backup, but this may be no bad thing, given that a backup is not supposed to be a mirror, nor a mirror a backup.Īny suggestions (or flames as to why my backup strategy will fail catastrophically) welcomed! # make the backup bootable - comment this out if neededīless -folder $DEST/backup/System/Library/CoreServices exclude-from backup_excludes.txt $* / /Volumes/Backups/backup $RSYNC -a -x -S -delete -link-dest=./backup.1 \ ! test -d $DEST & echo "Please mount the backup drive!" & exit # $* expands to any extra command line options you may give
