Change encryption key for repository

[matteu]

Hello,

I would like to know what happened when I change an encrpytion key used to encrypt data stored in a repository for nutanix backup ?
Is it the same as backup encrpytion ?
Do I need to keep the old one or only the new one is needed ?

Thanks for your answer.

You mean this - https://helpcenter.veeam.com/docs/vbr/u ... tml?ver=13 type of encryption correct?

Yes, with this procedure :

Yes that enables backup encryption. You're free to change the key as often as you like but I don't believe that you can remove old ones as long as the repository is still active...

Thanks for your answer.
What do you mean exactly ?
I would like to know what happen if I change the key today (because I lost it) and I used Enterprise manager to recover my data when I migrate to a new backup server.
Do I need the old one + new one or only the new one will be used ?
