Hello @Commvault Engineer
There is no way to do this unless you are using Intellisnap with Snapvault\Snapmirror. Commvault has no knowledge of the data on it if Commvault is not used to move it. The CommServe database keeps track of where and what files are on storage and can only track them if moved by Commvault.
Thank you,
Collin

Hi @Collin Harper,
Another question, while taking a look on documentation, we found this section “Replica Libraries”, which seems interesting in our case :
https://documentation.commvault.com/11.24/expert/146761_replica_libraries.html
Do you have any idea if this can be implemented ?
Kind regards.
As a backup engineer - This is something you would never do
But I have seen ‘some storage people’, some high level Architects and Heads of IT believe this should be done.
For CommVault - here are the caveats
- If you using storage replication, it would need to be synchronous (not Async)
- Your ‘source’ media agent - would have to be the media agent accessing the ‘remote’ replica
- I’m not sure how this would be useful in a ‘true DR’ situation
- I’ll leave it up to you how you re-connect the Maglib for read/write (it would be ‘like’ a Maglib DR scenario
- and you could possibly perform a ‘whole’ Media Agent DR at the remote site
What you loose is by not using Aux copy is
- Another ‘re validation’ of you data
- ie where the primary reads the data, re-processes it- and sends it to a second remote media agent
The real question is Why do they want to storage replicate something under the control of an Application, that just happens to be called CommVault
If this was a 50TB mission critical Oracle Database, Do you believe the Oracle DBA’s would ‘allow’ the storage people to use a Storage Replica (only) as the only remote/dr copy of Oracle
The thought is::
Commvault is an Application; It has highly detailed application requirements - and the storage folk would be ‘best’ to just give you the Capacity -and leave your ‘Application’ in control of the remote copy
(Even if you purely control that from a single media agent at the source location
Hello @Commvault Engineer
Reading over the documentation I can see how this may be appealing and may apply to your scenario, but in my 6 years of Support I have never seen this implemented so I wouldn’t be able to advise on pro’s\con’s or caveats.
We also have Inline Copies which may be worth looking into. Basically we backup to two copies at the same time.

Thanks a lot @Collin Harper, for your valuable support.
