EMC NetWorker Virtual Edition 19.1 Client Retention Policy Override

Hey guys, we would like to configure the backup retention policy and the type of backup that will be performed (Incremental, Full, etc.) per virtual machine (VMware environment + vProxy) not globally on a per-policy basis.

Is there a way for us, and also, is there a way for us to automate that?

I understand that there is a way to do that for normal Clients but for VMware Clients, I haven't been able to find any information.

As Marco said, the first fact is that you can do this only for standard filesystem backups because vm backups are always incrementals.

The second issue is that it is a pain to set this up. I am pretty sure that sooner or later you will be confused because there is no straight way to follow. As Marco said, the best way is to use a short retention for the backup policy/workflow and use clone jobs (prefered: scripted) which you run on a daily base to copy the full save sets to a volume pool with a longer retention. Such will also speed up potential recover processes.

Hello,

actually I can only suggest to use multiple workflows and each can be assigned to a different group, and use the different specification in the workflow.

Also with vm backup you can actually perform always incremental if you use the CBT+ Data Domain, the image is reconstructed and indexed using the changed blocks. And if you need a copy for long retention you can always perform a clone (even to other kind of devices), since the data should be rehydrated in the clone process.

Regards,

Marco
