Today I had a SQL 2012 server with a log drive there was running full. Veeam 7 is setup with application awareness, and should truncate the log for all databases. But to my big surprise it did non of the kind. The scarey part is that Veeam did not repport any errors in the backup status/history log. It turns out that there is a KB on veeam’s website, pointing out that the local SYSTEM account do not have permissions to trunkate the log’s. So you will have to give the SYSTEM account these right on the SQL server from the SQL managment studio.
I hope this will help you in some way, please leave a comment. Thanks for reading this!
