Backing up VM's with pass through disks

I've recently created a Hyper-V cluster with 6 VM's - 3 of which use pass through disks.

I would normally use Backup Exec to cover all backups, but I read it can't backup machines with pass throughs - it's also quite expensive!

ANy suggestions on

1. Alternative backup solutions for Virtual Machines (cluster/CSV)
2. Methods to backup the machines with pass through disks attached (no need to backup ANY of the data on the pass through disk itself, just the VM)

thanks,

You are right, a pass-through disk cannot be backed up from the Hyper-V host.

You can still back up the VM (its VHD disks) using a software on the host – it will skip the pass-through disks and generate some errors in the log but the backup will be valid.

If you care about the data on those pass-through disks you need to back them up from within the VM. I use Windows Server Backup to back the data on alternative network location and then I use my old favourite backup software to back up the backup files created by WSB on tapes: it saves me a lot of money in licence fees because I take a back up from one old server only instead of several new servers (my old software doesn’t support Hyper-V).

1 - If you're a SAN then there are definitely options here:  LUN snapshotting, replication, etc.  We can snapshot LUNs with our SAN and mount the backups to the host Backup Exec server as a local disk for normal backup.
2 - The VMs could possibly use Microsoft's built in Backup program.  This can be scheduled just like Backup Exec and it's free.
