It is never a good idea to overwrite running programs or the shared
libraries they are using. Sometimes you can get away with it using
rsync because it will write a new file and rename it when complete and
the way unix/linux works, anything with the original file open will
still see it until the last close. But, it doesn't look like you
intended to do that.

Why would your restore to /raid/home/user be affecting things under
/var? In any case, I'd recommend using rsync over ssh to the server
for the backups instead of backing up the nfs-mounted view.

How have you configured it to back up and restore localhost? If it
isn't using the stock commands over ssh, you may have gotten something
wrong in the layers of shell quote escaping and the restore command is
being interpreted incorrectly.
