Backup replicated volume
We have replication working between an SC4020 at Site A and a SC8000 at Site B already but we need to backup for archive reasons from Site B if possible since that is where our CommVault backup infrastructure resides.
I had an idea to map the replicated volumes to Site B vCenter (making the datastores read-only) then use CommVault to backup those VMware datastores. If I try to map the replicated volumes to one of the Site B vSphere servers I get a message saying this volume is already mapped to a server or remote Storage Center and this may cause corruption.
Does this warning still apply if I make the datastore read-only? Does anyone know another option to backup the replicated volume from Site B? There is currently no CommVault infrastructure at Site A.

Thanks for the quick reply. That's correct, we are doing async replication to Site B using replays from Site A.
Creating a View Volume would be a manual process right? So I'd have to create/map a View Volume every time we want to backup? We don't necessarily need application consistent backups of the backup data.

Are you doing Async replication where replication is based off of Replays/snapshots? If so, then you could try creating a View Volume of one of the snapshots and then mounting that. Obviously your backup copy would reflect the timestamp of the Replay.
The problem you are going to run into is VSS/application specific backups of the VMs. Doing it from the DR copy will not let you enable that functionality.

You can script the creation of the view volume and mounting, etc.
Also, CommVault can do pre/post scripts in the backup jobs.
And your next question is probably asking for help with the scripts!.. I'm not good at them, so I'd say engage Copilot for assistance unless another forum lurker wants to volunteer to help. :-)

Ok thanks I will look into that. It would be better if that was built-in to Enterprise Manager or Storage Center but that might work.
The other option is doing Intellisnap with CommVault at Site A but that would potentially require some additional hardware.
