Transaction logs are not able to start.

Hi ​@waqasali -

Aside from checking the Logs, and you can reference the specific location of your Job logs in the following URL by VBR deployment option you have (VSA or Windows), Support will be your best bet here:

https://helpcenter.veeam.com/docs/vbr/userguide/logging.html?ver=13

Keep us posted what they say if you can.

In this case I would wait on what support says since logs can be a challenge. 😜

Hi, you need to run cross-check

or try to run backup - not log backup

hi ​@waqasali 

is typically seen with Veeam Agent managed by Veeam Backup & Replication (VBR) when the backup metadata stored on the repository and the Veeam database become inconsistent. It often appears after repository changes, agent upgrades, repository rescans that didn't complete correctly, or corruption/inconsistency in backup chain metadata. Similar Veeam issues are associated with repository/database synchronization problems.
