Multiple Backups

Ive come to the conclusion that the siteworx GUI wont let you create more then one scheduled backup. In order for me to have multiple i will need to run a cron job. Im looking to run a backup weekly to backup the database of a single domain weekly.

I am unfamiliar how to use the interworx backup system. Maybe someone here can help me out or point me to the right direction?

I remember seeing documentation of this but can’t seem to find it.

Any help would be great!

Thanks
