Hello RocketMan,
The article that you reffer to, is associated with the old backup system, which allowed for more flexible configuration of backup plans. This system is available in the control panel as a separate section
Backups and includes four additional modules.
Starting from version 5.52 ISPmanager uses
a new, simplified backup system that can be found in the
Tools section --
Backups.
You can use both systems simultaneously to configure different backup plans.
