How to repartition Hyper-V server disks
Posted on 2012-04-03
I have been playing with Hyper-V server 2008 R2. I have done a lot of work on to virtual machine guests that I do not wish to lose. Both of these guests are backing up to an external nas using wbadmin/mksbackup front-end. I have tested these complete backups by booting each virtual machine from the boot CD ISO and re-imaging to ensure the backups are usable. All good
the trouble I seem to have, or rather had spotted is the actual Hyper-V host is one monstrous 1.2 TB partition. Backing this entire partition up to either USB two or the NAS is taking about nine hours. I have used thick discs rather than dynamic so the actual Hyper-V host sees huge partitions even though there is virtually no data on them.
I now think what needs to happen is the Hyper-V host rebuilt with a 40 GB partition. The remainder can be used to host the Hyper-V guests. Firstly is this a better way to have the Hyper-V host setup? My main objective here is to be able to create a fast Hyper-V host C drive image that can be restored swiftly if required as opposed to the whopping nine hour backup.
Secondly how can I wipe out the Hyper-V host but retain both of the Hyper-V guests machines as I cannot afford to now lose all of the work and configuration.
I look forward to your expert responses and Wellcome any other thoughts on providing solid protection for the Hyper-V host.
