Hi Ben,

You can disable the backup of the special DISASTER_RECOVERY:\ save set and instead, backup the regular VSS save sets by adding the VSS:DISASTER_RECOVERY=off keyword to the Save Operations attribute of the NetWorker client resource. When this keyword is set to off and the All save set is specified, the following VSS save sets will  be available for online restore operations:

◆ VSS SYSTEM BOOT

◆ VSS SYSTEM SERVICES

◆ VSS SYSTEM FILESET

◆ VSS OTHER

◆ VSS USER DATA

It is recommended that you create a second client resource for the host and set up a scheduled back up of the DISASTER_RECOVERY:\ save set for the second client resource as you may find that taking a disaster recovery backup every two weeks is adequate. However, you want to take Full backups of your data, including VSS system state data, more frequently. So creating another instance for Disaster Recovery ONLY will be suitable solutions and it will ensure that you can perform a Windows DR for the host. That is because for Windows 2008, 2008 R2, and Windows 7, Microsoft only supports disaster recovery that is performed offline ( Which is by recovering the DISASTER_RECOVERY:\ Saveset )

Hope that this helps you and answered your question.

Thanks,

Ahmed Bahaa
