Backing up Hyper-V clients with 126.96.36.199+
Can anyone please help answer a question about backing up Hyper-V clients, in particular what an incremental backup does?
I am making full backups of hyper-V clients (Windows 2008), with the ability to restore individual files. If I have taken one full and several diff incrementals, and then open a restore GUI, selecting "Hyper-V" restore, I am only offered the most recent full image to restore.
If I change the type to "Normal", I can restore files from the diffs taken after the full.
So, I can restore a full system from .vhd and roll forward files created/changed after the full. But what about System State changes after the full?
I reason that an incremental of a VM would really be equivalent to a full as it is a single file. Is there a way to include the System State in incrementals without doing the whole VM (apart I guess, from installing NB directly on the client)?
