We have about 20'ish VM running on a 3 node Hyper-V cluster, I'm using agentless backups for most of them. I've had a few issues with a small number of the VM's but I have one with an issue I can't seem to solve.
One of the VMs KEEPS DOING BASE IMAGES! It'll do the odd incremental but always seems to do a Base. Its just a server 2012r2 VM running our building control software (HVAC, etc) nothing special its only around 25Gb in size, and has VERY little data churn!
I could put up with the constant base images as performance, bandwidth, repo size isn't an issue, BUT as it keeps doing a base it breaks replication to our offsite Core giving a duplicate base image has been found error and replication stops.
Any ideas WHY its doing a base and how to stop it!
