A couple months ago we started to transition our backups (Exchange, SQL, and SharePoint) to Backup Exec 2012 from Microsoft DPM 2010. We were having a lot of problems with DPM so we looked for a new solution.
Since transitioning Exchange to BE2012 I would say we haven't been completely problem free and lately it's gotten really bad to the point of causing system outages for us. We have opened a call with Symantec, but its been over a week without a response. Myself and two other team members have called in about it a couple times. I'm hoping the community can lend some experience and knowledge for the time being.
Anyways...full backups will take 3-4 days to complete with our databases totaling about 4TB. I have been told by other members of my team that the bottleneck isn't on the SAN or the network. For this reason we are only doing a full backup every 2 weeks and incremental backups daily. Even the incremental backups take over a day so at most they run every 2 or 3 days, but almost always fails with this error:
"Completed status: Failed
Final error: 0xe000035e - The Backup Exec Agent for Microsoft Exchange was not used to create the last full backup of this database. You must use the Exchange Agent to run a full backup before you run a differential or incremental backup."
A full backup was taken previously, so it seems the error isn't accurate.
Additionally, we have been getting an average backup speed of around 200MB/min which seems very slow. Currently it's running one at 174MB/min. The backups seem to show a status of "updating catalogs" for a very long time.
Has anyone seen this behavior or know of any good troubleshooting steps?
