I assume this worked at some point? It looks like an issue with communication with server itself (not sure on what you server is running, but if on UNIX check if you have nsrjobd core dump which would match timestamp of this backup failure). I don't remember seeing anything specific to Hyper-V in 8.2.0.2 which is now out as first official patch, but you may wish to try that one as well.

Could be some unnamed partition which gets name temporary during backup? Anyway, if nothing has changed, usually to blame is VSS framework within hypervisor, but for that one would need to dive deeper in Hyper-V - my experience is 0 with it.

Why is there such an error error ...:
65208:nsrsnap_vss_save:d:\views\nw\8.2\nsr\vssclient\snapvsssave\nsrsnap_vss_save.h(225): Error initializing the job.

At the end of last week, I tested the virtual machine restore It-TestXp. Virtual machine NMM restored, but I have not checked the settings on this machine. It turned out that the machine was not added to the pool of high availability, which means that the virtual machine was not in the cluster.
