How? I assume you are planning on doing this with scp/rsync in
archive_command in upstream master.

and then send them to slave02 every 10 minutes, for example.

Sounds good. But why? Is it just to have redundunt archives?
On your upstream master you can also use a custom script which inturn would
be scp'ing the wals to 2 or 3 servers for archiving purposes

This will be done by rsync or something else.

No, you should not have a problem. Since rsync will also copy the timeline
