There may be a better solution, but I've been using a script of my own
devising to wake and keep (at least Windows) machines awake during a
backup. I didn't know if there was a client-side API to call to keep the
machine awake, so I implemented mine as repeated WoL packets (say, once
every 5 minutes) sent from the Linux-based bacula server through a daemon
started when a job starts, and stopped when the job ends.
My solution, hacky as it is, seems to work pretty well for Windows XP and
7, and is only about 100 lines of python code--sounds like it might not
work on OSX, if it insists on ignoring whatever sleep timer is configured,
unless the WoL packets are sent more frequently, but otherwise I had
thought it would work on pretty against pretty much any client OS (that
supports WoL, at least).
I'm happy to share it, if anyone thinks it would help them.

The whole aim of practical politics is to keep the populace alarmed (and
hence clamorous to be led to safety) by an endless series of hobgoblins,
most of them imaginary.
