Well, I am not sure what happened, but we got a critical alert from our monitoring system that one of the servers had 1000% memory usage.
Checked the server and Veeam agent was backing up its hourly backup and was just eating up all ram on calculating digests.
What's weird, it has worked every night on 1.5 with no problems and its only today after I implement hourly backups with 2.0 that its had this issue. Also it did 2 backups fine before hand and after I cancelled, deleted the backup file and started again its worked ever since.
My 5 other servers (ranging from 2008 R2 - 2012 R2) haven't shown this problem either. Just this server with Windows 2012 R2.
This particular server was also the only server that required a reboot after the upgrade from 1.5 to 2.0 (It was rebooted)
