Be careful with rsync, whose original purpose is mirroring, not backups. Specifically, if you&#x27;re using it as a backup system of any kind, you want to use the --delete-after option, or else your receiver might delete the file before the sender even finds out the hard disk is corrupt (--delete-before is default, which is dangerous for a backup system).<p>You may also want to set the --max-delete option, to avoid the scenario where the sender doesn&#x27;t have the volume mounted, resulting in the receiver deleting everything.<p>Be also aware that rsync is completely unencrypted, so you need to use it in conjuction with sshfs, ecryptfs, or some other method if you want security.
