This is the think I should have had tried before (without VSS). I was
using cygwin/ssh/rsync method before, came to know from other
discussion that it doesn't use vshadow/VSS, so I just ditched that and
configured from fresh as in Michae's blog w/o paying much attention to
how it works or how I could have avoided VSS. That's good point to
know for future. I guess one can avoid using VSS by not using those
pre and post scripts on BackupPC server side? or windows side will
need to be modified in that case?

Also, would like to know from others if they can help me with 'at' issue.

Thanks! This software is cool! I mean BackupPC :)
