Yeah, the rsync mirror option sounds pretty good. I think I'll look into
that.
At the moment, I'm using my laptop as a mobile workstation. As such, I'm
attempting to find a way to hookup the laptop to the server and generate a
backup while I'm asleep.
What would be some of the next steps I take?
My guess is that I do the following:
1. setup a passwordless ssh connection
2. configure backuppc
3. have scripts on the laptop to make sure it connects to the server and
initiates a backup to the server
I believe I can do step 1, but do any of you suggest any particular way I do
it? Should I make a separate user on the laptop and/or server and give it
root permissions?
In relation to step 2, should I be using rsync if I am transmitting
information from the laptop to the server? Furthermore, I have the server
and laptop setup with different users and the permissions and who owns what
on the files is varied. If the user ownership varies yet the file is the
same, will backuppc attempt to backup the entire file, or will it simply
find a way to tag on the ownership differences without backing up the entire
file again?
I believe I can conduct step three, but if there are ever issues, I'll
simply generate another email to discuss them.
Thanks for the help.
