Can't backup without sites selected, can't configure scheduled backup without sites selected

Wanted to backup only the virtualmin pro config, not any site.

Couldn't. Had to select a site to backup at same time.

On new site could choose to not restore site, but only virtualmin backup.

----

Wanted to edit the scheduled backup which got restored correctly on new server: couldn't save, because of error:

Failed to save scheduled backup : No domains selected to backup

Even if I selected "all virtual servers"...

----

Imho, by default, the "Virtualmin settings to also backup" should all be selected by default.

It would also be useful to have a "select all / invert selection" toggle there.

----

nb. Filing separate bug report for the NON-backuped features of virtualmin as it has higher severity.
