We are currently backing up all of our content through one data center, but will be setting up Commvault in a second location soon in our peer data center. Once we do that, we will have our various branches backing up to the two different Commvault sites. We will be replicating data via HUR and have copies of the data on tape. My question is about the recovery of backups in the event of a disaster.
Let's say we have the following:
Data Center 1:
-Branch A backup
Data Center 2:
-Branch B backup
We lose data center 1, are we able to restore the content of branch A through data center 2? Given all of the configuration issues we have experienced with Commvault thus far makes us hesitant to use the dash-copy feature, so let's assume that's unavailable in this scenario. Would the two Commvault sites be aware of what the other is backing up via the deduplication databases so they would be able to restore data effectively?
The other question I had around this concern relates to future backups. In that same scenario, let's say we wanted to start backing up branche A via data center 2 since we lost data center 1. Would we need to take new full backups? Or would creating a subclient with the same name be enough for Commvault to recognize the data is replicated over on disk, then it will start backing up by taking incrementals with data center 2?
