Can restore backups made by master admin?
By default, virtual server owners can only restore backups that they made
themselves. However, if this setting is changed to Yes, backups made
by the master administrator (root) can also be restored by domain
owners. Naturally this only applies to their own domains though.
You should only enable this option if you are sure that all your backup
destinations are secure, as restoring a backup made by an un-trusted user
could compromise system security.
