Is it possible to backup a VM running with VirtualBox?
"vboxmanage export" requires exclusive access to the VM.
I know Hyper-V can backup running instances of VM, I was just wondering if it can be done with VirtualBox too.
I believe you could take a snapshot of the VM and then back up the idle VDI and then remove the snapshot when your backup is complete.
Other methods would include using snapshot features of your storage system (LVM, etc) in order to capture an idle VDI and then backup from the storage snapshot.
Here is a bash script that I use. It can backup a running VM, but it shuts it down during the backup. You can then fire it up again. I don't think backing up a VM while it's running is possible.
The other caveat is that you need to manually merge any snapshots for this to work.
