Disaster Recovery Options

The Disaster Recovery options available are:

• Generate DR information for partially selected nodes--Disaster recovery information is normally generated when performing a full machine backup. However, there are special cases where you may need to keep the disaster recovery information updated but cannot perform full machine backups too often (like in a SAN shared disk environment). By enabling this option, you can generate or update a machine’s disaster recovery information without having to back up everything on the machine.

• Include filtered sessions when generating restore session information--When generating disaster recovery information, the Arcserve Backup server keeps track of only the latest non-filtered backup sessions pertaining to the machine. By default, if you back up a machine using filters, the filtered backup sessions will not be used by disaster recovery when recovering the system. By enabling this option, you can alter the default behavior and have disaster recovery use the filtered backup sessions when recovering the system.

Important! Enabling this option is very risky, especially for system volumes. Missing system files may lead to incomplete recovery.

• This option is disabled by default. When you enable this option, it works at the job level. If the job contains multiple machine backups, this option will apply to all machines.
