Re running a plan fails with 400 error on VyOS operating system VM

[lauragiles]

Running a plan for the second time after spinning up 2 vm's running VyOS the plan fails with this error.

(HTTP 400 / REASON_554): Backup is not supported for Operating System DEBIAN6/64 (DEBIAN664)

Can we support this? is there a work around?

Other servers running ubuntu seem ok
