I am starting a backup to perform an upgrade from 4.0(3) to 4.0(5) and i have been looking over everything. The initial DBWalker went fine, but i had an error in the eventlog that states "error event id 17055 + 3041: BACKUP failed to complete the command BACKUP LOG UnityDb TO UnityDbDump". I know that this is related to the SQL DB, but I don't know if this is a mission critical that gets fixed before the upgrade, as I am not sure if the error is streaming from the server itself or the backup system. I have been searching both Cisco and MS, but no one can isolate this down. Has anyone run into this before? And if so, is this a critical error or is there a workaround?
Open Enterprise Manager
Right-Click on UnityDb database and select Properties
Click on the OPTIONS-tab
Change the Recovery model from SIMPLE to FULL.
Go to the Nightly backup job, right-click on it select "start job". Check the app logs after a few minutes
