I'm backing up a Linux machine (Ubuntu 10.04) with rsync over SSH.
If I specify for my path something like "home/jason" it works just fine. "home/jason" is translated into "/home/jason". But how do I back up my root directory, i.e. "/"? Logic would have it that, since a slash gets slapped onto the front of whatever you put for path, a blank path would come through as "/". That's not the case, though. A trick like "home/../" doesn't work, either.
How do I back up the root directory?
Turns out putting "." works because it translates into "/." which is equivalent to "/".
I take it you've tried "/"? If that didn't work, what exactly were the symptoms?
I think you need to create a module for "/" in rsyncd.conf (on the box which you're trying to back up.)
Something along these lines:
Get rsyncd to reload the config, and you should be able to use "root" as the path in the Frontview GUI.
See http://linux.die.net/man/5/rsyncd.conf, especially the examples towards the end of the file.
