I have a 6 host Hyper-V cluster on Windows Server 2012, running about 60 virtual machines. The hosts have fibre channel connections to my 2 FAS2240-4's. All the virtual machine's vhdx files are stored on a 4Tb CSV, which is accessed by the hosts through these fibre channel connections.
I have setup SnapManager for Hyper-V to do backups of these virtual machines. After the first scheduled run of backups, I noticed that the backup files are actually quite small, which makes sense if only the VM definition is backed up.
1. I have been running this virtual environment for about a year, and have never had a VM go corrupt. In which instances would this happen, requiring me to restore a copy?
2. What is the best practice for backing up the VM's vhdx's in a Server 2012/Hyper-V/NetApp FAS environment? Is this where FlexClone comes in?
