If you have an existing backup or DR strategy that can handle physical
machine/disk failure (which might involve OS-level backup or disk
image), you can also use that.
Last time I check with Ubuntu, it's initramfs pretty much includes
everything so that you _should_ be able to move/copy the entire disk
to another physical machine (including HVM domUs) and have it running
with minimal effort. Latest -server kernels also supports running as
PV guest. Perhaps some of this is also true for Debian.
