Hey,

First of all, thanks to everyone involved for life-saver software.

I've a bit of a grief when restoring to WinXX shares (both over smb
before and rsync now), and I've failed to find enough information to
understand how BackupPC goes about that.

When restoring data to a NTFS filesystem I've encountered permission
issues which either
a) prevented the user from accessing his/her data
b) the restore process seemed to have locked itself from writing down
the tree by changing permissions of a parent folder so that it couldn't
write anything below that folder

Those weren't critical issues since I could still get at the data in the
end, but it was far from ideal.

To note is that on both of the above the underlying OS was reinstalled
from scratch, so I'm suspecting that user ID mismatch might be the
reason, but I've failed to confirm that.

I'm now using a cygwin+ssh+rsync approach to back up WinXX machines, as
it seemed a bit more secure and "behind the scenes" as opposed to just
sharing whatever was needed over CIFS. I've rougly followed the guide in
[1]. Is rsync indeed the recommended solution for WinXX backups? Is
there something I've missed re: permissions that I should've taken care
of? Or is it simply that the "clean OS" case is crippled by mismatched
user IDs? Maybe using a Samba domain to store users' credentials would help?
