[bitfolk] LXD/LXC of Bitfolk VPS

Hi Everyone (Andy especially) Have any of you done a "P2V" (ha!) of your VPS into LXD/LXC? I've done some Googling, and from what I see, it shouldn't be too difficult in my case: the VPS is running Ubuntu 16.04.4, there's a template for that, I've plenty of room on the "target" LXD machine for a <10GB fs. But... I'm wondering about the feasibility of getting a tarball of the VPS fs (Andy?)? I've got space on the VPS in question to make a tarball of itself, but I'm not sure that would be the best idea (writing to the very FS I'm trying to archive, just feels wrong before I try to do it). Thoughts/comments sought/appreciated. Kind regards Murray Crane
