We have a protected 2012 R2 server that has Data Deduplication enabled. DPM tried to create a recovery point and ran out of disk space. When I check to see what happened, the job had transferred over 43GB of data. This is way outside of the norm for this protection group. Upon investigation I found that a scheduled weekly defrag had run. I assume this to be the source of the churn. Can anyone provide an guidance on the interaction of the these processes? The scheduled defrag was enabled by default. I assume we'll need to disable this? I have never defragged my VM's as it would cause massive churn for the VM backup's in DPM. But this was not a VM backup, just a backup of files on a deduplicated volume.
Thanks,
Scott
