Using DPM 2010 to backup several computers, hypervisors, and the DPM server it self, a stand alone server all of a sudden no longer backs-up within a reasonable amount of time. This is just happening on the C drive and System State. The D drive and all other servers and hypervisors are running smoothly. You can see below that something changed on December 11th. Backups for those two items when from about an hour to over 10 hours each. This is causing all other backups that have yet to run to be canceled because we do not typically like the backups to run during business hours.

No changes to the server had been made. Updates were not applied to that server until December 18th. The server has been restarted. The agent version is the latest v3.0.7706.0. Ran the command "vssadmin list writers", show no errors. Any insight would be appreciated. Thanks in advance.

I forgot to include that this also happened on the DPM server itself, on the same day. The C drive and system state went from under an hour to several without cause or warning.

I Decided to disable McAfee VSE on the DPM server itself before the nightly backup started. The next day the C drive and the system state went from several hours to well under an hour. I'm not sure what started this so I'm not sure what company I should be turning to get this looked at and perhaps fixed. For now disabling AV brings the backups in line.
