general/other Complete VM backup & restore

Hello there,
I m currently running a live freebsd-12 VM with google cloud and I would like to move the image to another provider; is there a way to complete backup & restore the "Live Server" while it is running and restore it to another VM with another provider?

saw many articles about rsync, dump ... but still the solution is not quite clear for me.

Thanks a lot for your kind response and support
