Can you this? yes.
Will it work? if you do it correctly, absolutely.
Will anyone in commvault recommend this to you?
No, not likely in fact I suspect most will recommend against it.
Have I done in personally yes? Probably 2 dozen times. Will I recommend you do it? no.
Thank you for your answer… but it doesn’t really help, as I was hoping for tips/recommandations…
Why do you not recommend doing it?
So, my understanding here is, there is only one copy (Primary) with the problematic QNAP (before it got wiped out)
Then you have procured a temp QNAP and started backing it up.
Once the old QNAP is fixed, you have a created a fresh DDB on the MA and planning to move the data from temp QNap to the fixed QNAP.
If the above is the case, you can do the following
1. Add the new Disklibrary (fixed/mew QNAP) to the same MA.
2. Add the (fixed/new QNAP) to the same stoage policy as “Secondary” where the temp QNAP is marked as primary
3. Make sure the Library is in read/write mode
4. Initiate AUX copy job from Primary to secondary
5. Once all the data are transferred, rename the Primary as Primary_temp.
6. Promote the Secondary copy as Primary.
All the data inside the fixed/new QNAP will become primary & you can remove the temp QNAP.
Thanks for all the replies guys
We actually created a new ddb for this new Library and did an aux copy from the old primary to the new one (that will be promoted, when done)
