I think that's a scenario you best forget as soon as possible.
Replicate to a running system.
Backup on other media (like CDR or DVD).
Don't expect book-keeping software to run if you just have copies
of the files. It's probably far more complex. Consult the
software's supplier for a viable way to backup their system.

If you keep data and OS on the same partition you will need to
replicate --and backup-- that entire partition. And that's quite
a challenge as several 'open files' cause problems only the best
backup software can cope with. And it produces datastream with a
very low 'yield'. (Backed up data versus viable data.)

It never will. Only an OS installation CD will perform such a
task.

As a rule, any (external) recovery will cost you far more than an
extra PC would
Say, you operate a business from (mainly) a single PC and you
want that business to keep running uninterrupted, a second PC
with data replication (and an UPS) would be quite a viable
option.
You have to decide what it would cost you if your (main) PC fails
for 10 minutes, for an hour, for half a day, a day, etc.
That is, the costs of your business being unoperational added to
the costs you incur to restore to a running system.
And keep in mind, that if you run into a hardware failure, you
are likely to need an extra PC anyway.
