Simply-Scripted Backup is a lightweight utility for performing backups. It does a straight copy of files and folders (when the source is newer than the backup) and optionally stores the old backup file versions under a time-stamped folder. It can also clean the backup by deleting (or optionally moving to a time-stamped folder) files and folders that no longer appear in the source.
As an additional feature, the backup can be compared with the source, including a byte-for-byte comparison...
