Im having issues with wbengine.exe I know its the block level backup for WSB however its killing my server (see below) we are running on 2 x 600gb R1 SAS 15k disks for where the os VM is stored and 3 x 1tb nearline 1tb disks 7.2k where the data for essentials ("server folders/folder redirection" is stored with another virtual server doing very little in the background there is plenty of memory and cpu for all vms (just the two)
we have a backup on the vm start at 8 and finishes around 10 and a host backup that starts at 11 and finishes around 1
backups locally from WSB dont show to of started however they did on the host with warnings any ideas ?
UPDATE:
After talking to some users the issue occurred on yesterday morning, it looks like WSB is causing issues backing up when on schedule, as looking at the CPU usage from 8 at night last night. Thats when it started maxing out and the backup began, a single one off backup seems to work fine using the settings of the schedule but scheduling seems to kill it.
To note this is going through ISCSI
