The current meaning of --files-from is to restrict rsync to processing the paths in the list, and rsync deletes extraneous destination files as part of the processing of the parent directory (assuming -d or -r is on), so you can't delete unlisted files this way. See: https://bugzilla.samba.org/show_bug.cgi?id=3465 Try this instead: rsync [OPTIONS] --include-from=/tmp/BACKUPFILE --exclude='*' /var/data/shares/vmbackups/ /mnt/usb_backup/SFSYDVS01/daily.0/VM/ This way, rsync will scan the destination directory for deletions (since you have -a without --files-from, which implies -r) and will delete the old files because they are excluded with --delete-excluded.
