Disaster Recovery - 7.6.x vs. 8.x
I have noticed a change in DISASTER_RECOVERY:\ saveset in 8.x and I want to make sure it is by design. In 7.6..x, there sued to be OSSR_x savesets that were the same size as the crtitical volume. If F:\ was 500Gb, OSSR_F would be 500Gb also. I upgraded one of my backup server and 1 client to 8.x. I did not notice this until this week, the OSSR_x was no more. I only see DISASTER_RECOVERY:\ save set.
Hss anyone who upgraded from 7.6.x to 8.x noticed this? Obviously, I like it because you are not backing up the data twice. But, I need to make sure that the change in process was by design.
Any thoughts, comments?

Hi,
OSSR is Offline System State Restore
In 7.6.x, the components of the `All` Saveset is (for Windows 2008 R2 when level is FULL):
- DISASTER_RECOVERY:\
- All local physical drives
In 8.x, the components of the `All` Saveset is (for Windows 2008 R2 when level is FULL):
- DISASTER_RECOVERY:\
- VSS SYSTEM BOOT:\
- VSS SYSTEM FILESET:\
- VSS SYSTEM SERVICES:\
- All local physical drives
As you see, as of version 8.x, the OSSR (Offline System State Restore) is no longer needed.. because now NetWorker is backing up the other 3 VSS Savesets instead of the OSSR Savesets. This is a good enhancement... For example, if F:\ & H:\ are identified a critical volume and they are 1 TB each, then in version 7.6.x you will get 2 TB for the OSSR Savesets.. while now in version 8.x NetWorker will backup the 3 VSS Savesets instead of the entire 2 Critical Volumes.
Regards,
Mustafa

Mustafa - Thanks for the confirmation. I am glad the change in 8.x in regards to disaster recovery saves time and space. It did not make sense to backup the data twice in 7.6.x.
This would be a good reason to upgrade to 8.x at all my sites.
