Hi Cahvdar. DP for Hyper-V relies on Microsoft to provide incremental support. The provided method uses differencing disk (avhdx) to keep changes between backups. Other backup vendors may have different ways of tracking changes.
If you need to resize disk after a backup you don't have to merge avhdx into parent vhdx file. You can shut down the VM and resize the avhdx file. Than, during next backup, the changes in avhdx will be merged into vhdx file. That's it. No need to do a full backup after disk resize. Incremental backups chain will continue. Regards, Vadzim.
