A while ago our sysops guys created a 15 minute transaction log backup schedule using Microsoft DPM. We often have an issue where there won't be enough space on the Log drive to perform a backup because DPM creates its backup on the same drive that the logs live on. Eventually, because DPM can't back up the logs, they get larger and larger and the problem gets worse and worse until I run a manual backup of the bloated logs through SQL Server (and then, sadly, I have to run Shrinkfile on the logs that bloated).
I can't find any setting or option in DPM that allows me to write the backups to a different drive with more space instead of the drive that the logs sit on. Does anyone know if it's possible to do this and how?
