Seems like something you could test easier than explaining the
question here... Commands like 'ls -R /cygdrive' can recurse over
the letters that appear so it seems theoretically possible.

Even if you can, it might be a good idea to separate the schedule and
failure modes from the main machines. If there are some reasonable
number of target pcs and drives that could go with each, why not make
each possible target a 'host', like andy_e, andy_f, betty_e, betty_f,
etc.? You can create these with the NEWHOST=OLDHOST syntax, then
change the clientaliasname and sharename for each to the pc and drive
you want. That way it will be easy to start a run for any particular
drive if the user wants to do it explicitly from the web interface and
you don't have to save a large number of backups of the main machine
and wade through them in the hope that you'll find one containing the
drive.
Alternatively, you could just have the users rsync the contents
regularly to a matching place on a dedicated file server that backuppc
backs up to keep a history.

Why Cloud-Based Security and Archiving Make Sense
Osterman Research conducted this study that outlines how and why cloud
computing security and archiving is rapidly being adopted across the IT
space for its ease of implementation, lower cost, and increased
