DPM replica is inconsistent. Basically you will need to do a lot of patching on the hosts to get the agent installed. Patching can be OS patching and Application Patching (SQL, Exchange). Other Notes 1.) If you continually error out when running a consistency check verify the server has enough space.How many guests are in the replica is inconsistent state?
I currently have a Hyper-V 2016 server that I am backing up using DPM 2016, Now the Hyper-V host its self has roughly about 50 VM's and about 35 of them are backing up without issue however I have about 15 guests that are all in a "Replica is inconsistent" State with the following error in even log :Why is Microsoft DPM inconsistent with different datasets?
Patching can be OS patching and Application Patching (SQL, Exchange). 1.) If you continually error out when running a consistency check verify the server has enough space. With Microsoft DPM we noticed that different dataset types (DC, SQL, Exchange) have different host storage requirements.What causes a DPM job to fail in a backup?
For us it was signifigantly more than we were use to with other backup systems. DPM jobs will often fail when the host or the DPM server itself is using too many resources (Network, CPU, Memory). Make sure optimize the protection groups so that the resource consumption is spaced out.
