Hi George,
I run BackupPC on Ubuntu Linux to backup my data. Several years ago, I
was running a windows network with a file server housing all of the
data. I am trying desperately to totally stop using windows, but it's
tough when so many vendors will only support Windows systems. But that
is not the issue here...
I am not any kind of expert on BackupPC and still consider myself a
little wet behind the ears when it comes to Linux as well. While this
doesn't address your problem, it may be a direction that will get the
desired results.
My server is now a Linux box serving files to Windows machines via
samba. All data is served from this machine. Another machine is
located in a separate building, running Linux and hosts the BackupPC
system. This machine is also set up as a samba server and can be
quickly placed into service if the primary server fails and cannot be
quickly repaired.
I manually make images of the windows OS for each machine (no data
files, just OS) after hardware changes or major system updates. Now,
BackupPC is only backing up Linus systems via rsync. (It doesn't know
or care that a lot of the backup data is for the windows clients.)
I am retired and some nights I can't sleep. I work all night on
projects and I am unaware of the BackupPC process running in the 1 am to
7 am time span. It doesn't impact my work whether I am working in
Windows or Linux.
Just some info that you may can use. -- ken
