Hi.

I have a Hyper V server with a DC and Exchange 2010 box as guests. I have got an external tape backup drive and Backup Exec 2010 R3.

I would like to load backup exec on the Host WHICH IS NOT ON THE DOMAIN and use remote agents to back up the DC and Domain Controller Guests.

Is this possible.

I would advise against running Backup Exec on the host, merely because of how resource intensive it is when backing up.  You will also need SQL Express to be installed, and SQL likes to eat memory up like it's going out of fashion.

However, to answer your question, yes you can do it.  You configure Backup Exec with accounts it can use to back up remote machines, and you can use the credentials of the guest domain for it to be able to install the agents, and connect to them.  You can have multiple accounts, so you're not limited to one domain.

Thanks for the quick response!

I have loaded the backup exec on the host server and used the push install to connect to and install the remote agents on the domain controller and exchange 2010 server.

The server was set up in this way.

Created RAID 5 Array and created 3 x  200GB Volumes and 1 x 1.8 TB Volume. I left some space undefined for future use.

I then loaded my Hyper V host on the first 200GB Partition and added the second and third 200GB Partitions as E:\ and F:\ in disk management.
I loaded the Hyper V Role and created two VM's with default 127 GB Partitions
Domain controller with VHD files located on E:\Hyper-V\DC
Exchange Server with VHD files located on F:\Hyper-V\Exchange

I added the 1.8TB Partition as a passthrough disc on the Exchange VM by adding it to a SCSI controller.
Installed Exchange and moved Exchange Database to the Passthrough disk. (I read a couple of posts and came to the conclusion that the database would run faster on a passthrough disk.)

I see that backup exec does not support passthrough disks. I have set up backup jobs to run with the remote agents for the DC and Exchange.

I will create another job to backup the main partition (C:) and the system state of the Hyper V Host.
This will be a manual selection job as I do not want to back up the E:\ and F:\ as the servers are already backed up. Should I select the Microsoft SQL Server (BKUPEXEC), Shadow Copy Components and Hyper V Initial store as well?

Is this good enough or....

Do you think I should change the passthrough disk to a VHD and only backup the lot with the Hyper V Agent?

Backup Exec should not care that it's a pass-through disk or not.  If you're using agents on the two virtual machines, then you should be using the standard agent features.  Back up Exchange on the Exchange Server, and do a System Backup on the Active Directory.  You should not need to worry about backing up the volumes that the exchange store is mounted on.  From a virtual machine's point of view, a hard drive is a hard drive - regardless of whether or not it's a VHD file or a pass through disk.

The good thing with pass-through disks is that it allows you to increase its size without having to shut the Virtual Machine down.

I installed Backup Exec on the HyperV  host with remote agents to back up the domain controller and exchange server.
