Nimble Snapshot Replication issues after upgrading to Veeam 9.5 Update 4

Post by bgutan »

Since Upgrading to Veeam 9.5 update 4, Nimble snapshots taken on a primary array which are then replicated to a secondary array replicate the entire volume instead of just the changes. This is causing my backup window to greatly increase. Per Veeam support, Case # 03404627, nothing has changed in the code with the Nimble snapshot replication between update 3A and update 4. I reverted back to my Veeam 9.5 Update 3A server and I have no issues with snapshots. Anyone else using having issues with using Veeam to replicate snapshots to secondary array since upgrading to Veeam 9.5 update 4?

Hello Bryan,
and welcome to the forums.

I talked to support & QA and we will continue investigating your case. That does not look correct for me.

Thanks for bringing up that issue,
Hannes

Hi Bryan, we have other cases with similar issue and Nimble support is also involved. Working with them to get the details. Thanks!

It is not decided yet. There's however a registry value that should help to eliminate the issue: NimbleKeepTransferSnapshot (should be set to 1, standard Veeam key on the backup server: HKLM\SOFTWARE\Veeam\Veeam Backup & Replication).

I re-applied update 4, added the registry key, and it resolved the issue.

Thanks,

Bryan
