Aaron is right, however you'd better make regular backups; plenty of things can pass incorrect with this selection with reviews; it is complicated and syncing equipment like Dropbox/Nextcloud/and so forth have been no longer designed for this :)
A brief restore became to create a post backup script in an effort to problem chmod of the tar report as you can read. We failed to find a solution through webmin for chaning permissions during backup or inside webmin panel.
