backup: push or pull?

Just a general question:

I have 2 machines, A and B, similar setup. I want to have a backup of both.
The way I'd do it is to make a copy (tar) of A and put it on B and the other way around.

What is the right approach to do it:

Schedule a job on A to PUSH it's backup to B (and the other way around)
schedule a job on B to get (PULL) the files from A (and the other way around)

It doesn't matter HOW the backup is happening, it'll probably be rsync and/or nfs.

I think the second one is better... You'll be immediately notified if a backup fails in that case.

That would require ROOT access to EVERY file on A from over the network... Isn't that a bit dangerous?

Well, I don't think so, if you copy the files from nfs.(As you have stated!)
