We haven't seen this issue previously. So, you'd better contact our support team directly team.

Just to be sure - by "manual incremental" you refer to VB&R backup job, not to the one executed via SQL native tools, right?

Thanks

Hey there,

I wonder if there is simple solution with this issue? We've got same error on our small installation. We have latest Update 2 on 9.5

Error occurred while performing SQL Server transaction log backup Details: Unrecognized Guid format.
Transaction logs from some databases were not backed up for the last 6 intervals

Any idea?

Thanks in advance.

Hi Lenart, I cannot track the issue, since there's no support case ID. Please contact technical support directly for a closer look.

Hi,

thanks, but I was able to resolve this isue.

When I connected to server with SQL I've found out that it was in folder %programdata%\Veeam\Backup\ another folder SQLLogBackup which was dated 3 days ago (that was when problem started), this folder had some files xxxxxxx.BAK, which are obviously backup files created by Veeam/SQL agent. So I stopped the SQL log backups on Veeam B&R and afterwards I deleted this folder. After this I simply started the job and voila :).
