Backing up VHD files on Hyper-V 2008 (non clustered)

I've talked to some people around my department and they have said you can back up VHD files on Hyper-V 2008 (non clustered) and back them up while the guest is live and running (with PowerShell scripts).

Can anyone give me more information on this? What kind of back up? Is it an export? Thanks for the help!

Thanks. We'll let you know when a new response is added.

Have you looked at BackupChain? Because maintaining scripts sooner or later is going to be a PIA…. Also you’ll definitely want dedupe unless you have unlimited storage to work with….

    My understanding is this is what VSS is for.  The Microsoft VSS pauses the virtual to take a backup snapshot and then resumes the virtual.  You don't have to down and restart it and it does not take as long as it would if you were doing it by hand.  The important part of backup is the restore.  Using Microsoft backup, you can restore the whole virtual, but you cannot restore individual files, etc. from inside the virtual.  Many 3rd party backup products use the Microsoft VSS but also allow you to restore individual items from inside the virtual as well as the whole virtual.
