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.
