I recently upgraded from BE 2010 R3 to BE 2014. I've noticed the throughput on my jobs has dropped significantly, espcially for jobs backing up Hyper-V Virtual Machines. The servers in question are in a Hyper-V cluster running Server 2008 R2, and the backups are being written to LTO4 tape in a Dell TL2000 connected by SAS.
Prior to the upgreade, my two Hyper-V jobs would get between 4000 and 4800 MB/min, depending on other network traffic and normal variations.
For two days, I ran BE 2014 but with the old agent on the Hyper-V servers. On those days, I got between 4400 and 4700 MB/min.
Since upgrading the agents, I am now getting between 2100 and 2600 MB/min. Obviously, this causes my jobs to take longer to complete.
Any ideas if anything can be done to restore the former speed?
Thanks!
