i have a HYPER V cluster with 4 nodes on 2008 server R2. Network is 2008 server R2 as well dor active directory.
All my Vms are 2003 server and 2008 server R2.
Each node has 2 virtual servers. In reality one server by itself can only hold 4 VMs because of hardware and license. So i have spread the VMs 2 on each node and if one node fails the two VMs can easily fail over to the other servers. So everything is load balanced so far. These 4 nodes are connect via 1Gb iSCSI to a SAN Cluster. So the two SANs can failover as well for high availability.
However from a backup stand point, doesn't this setup quadruple my cost to have automated backups? i would have to have one server do the backups and have to migrate each virtual machine manually to that server and run the backups.
Or am I mistaken since the 4 nodes act as a single Server/cluster. Currently i have no backup solution other than detaching and saving the VMs to a usb hard drive. This is so annoying and time cnsuming because i only have USB 2.0. Copying 900Gb takes all day. I usually take vms down after work friday and let them copy for 24 hours and come back to pickup the drive the next day.
I'm looking to setup a server at home and maybe VPN a tunnel to have off site backups using a software solution if I could find one and not have to go trough this weekly process of USB Drive swapping.
I'm covered from a hardware failure but i want an offsite backup and a quick restore should corrupt data or have a failed update.
