It won't do anything in weekly.local; the weekly script doesn't handle ROOTBACKUP. You could use a shell conditional in daily.local instead: [ $(date +%a) == Sun ] && ROOTBACKUP=1 I advise against using ROOTBACKUP here though. It just dd's the filesystem. If the run is taking a long time, there's a high chance that your backup will not be consistent, both due to the filesystem changing during a backup, and due to overwriting the old backup with the new one. I would prefer to use almost anything else though and get versioned backups. Probably my most used backup/restore action is to get back a version of some file from yesterday so something that will only write the changes is useful. I quite like borg for this but there are many options.
