Constant CBT resets and slow Replication performance after applying VBR 12.1.2 patch

Constant CBT resets and slow Replication performance after applying VBR 12.1.2 patch.

Security patch is closing CVE-2024-29849, CVE-2024-29850, CVE-2024-29851, CVE-2024-29852.

After patching our VBR servers with the 12.1.2 security patch (https://www.veeam.com/kb4581), CBT keeps getting reset and our Replication jobs that used to take 2 hours are taking 12-14 hours now.

Anybody seeing the same issue?

We have engaged with Veeam support (Case 07270614, created on May 22) and still no resolution.

Thanks.

Hi Juan,

Thank you for sharing the details and the case number, and sorry to hear about the unexpected behavior. While I have heard of a few reports of slowness, no known issues right now and the cases I'm aware of had other causes (orphaned snapshots)

Please continue working with your Support Engineer, as based on the case notes they'll have some additional steps to review with you soon. If there are concerns on the handling of the case, please reach out to Support Management and explain the situation, they will be able to review the case and assist accordingly.
