System retention rules retain one bare metal backup per client per week. It is recommended, at a minimum, to perform a bare metal backup of the clients every 30 days or anytime a patch is installed or software is upgraded on a client. A bare metal backup for a client should also be performed anytime a new network or primary hard disk (SCSI, IDE) hardware is added or any significant configuration changes are made to the server. In order for a crashed machine to boot and work properly after a bare metal restore, make sure all the new settings are present on the server. Test the new settings by booting from the newly made metal crash recovery media and make sure that the network and disk have been properly recognized. To do this, go to Utilities > Advanced > Change Settings.
