How to backup a VM not on the DataStore or add a USB HD to a Datastore

I'm in a situation where I need to backup a VM but I don't have enough storage on my current datastore. Is there a way I can make a USB Hard Drive a Datastore? I really need to backup a VM to another source, any suggestions?

Current datastore is internal Raid.

Why not just browse the datastore and copy the files to a local PC harddrive from the datastore browser?

Alternatively why not use Veam fastcopy

Well, not 'Fastcopy' but FastSCP :P ( For datastore browser or FastSCP copy solutions, there are a couple things to keep in mind -> 1. The VM has to be powered down to do the copy; 2. your VM backup is obviously only as current as when you did the last copy.

USB mounted on ESXi host isn't supported I'm afraid, even if you are currently using something like ghettovcb. If you really need it on USB then creating an NFS share on the USB attached to another machine and mounting the NFS as a datastore is possible, although it's not going to be fast or pretty.

Didn't know I could do that. Let me try now.
Yep...just rt-click on your datastore and select 'Browse Datastore'. Then, it's pretty much just like Windows Explorer...kinda. You can rt-click on the whole VM, select Copy, then copy it to an attached network/USB location.

But again..don't forget to power down your VM, or you'll get an error saying the 'disk is in use' or something related...
Stop the VM
Browse the Datastore with Virtual Infraestructure Client, selec each VM file->Download
Download the VM files from DataStore from a PC with the USB HD conected.

Thanks for the fast response. Our Server crashed this morning and I want a full backup of the current VM encase it happens again. The easiest way was to use the datastore browser and download the files to the local machine.
