XWiki on USB Stick or emergency backup and restore

Hi Together,

we`re actually building a emergency plan for our organisation. Actually, our XWiki runs on a Ubuntu VM on VMWare. We would really love to have the posibility, to have a copy of our XWiki on a USB Stick, so that we could easily get some information out of it, in case, that our VMware is down.

Did anybody alreay got Xwiki running from USB Stick or is there another easy way to backup XWiki and restore it on an Windows 10 PC?
Thanks a lot!
