Hi, sorry for hijacking but I have this exact problem but with the VeeamBackup database. We are running SQL 2012 Express and upgrading to standard is not an option right now.
VeeamBackup db is 10GB
VeeamBackup_log is 7,5GB
Using SQL Studio Manager shows me the biggest tables
Which tables are ok to purge and how? Or can I just create a new DB and how do I do that correctly? What happens with my backups if I start using a new db?
