I'd use rsync for this, running over ssh. The "obvious" place to do this
is as part of the existing cron job, immediately after the backup has
completed.
(a) from server1 to server2:
rsync -avP -z -e ssh /path/to/*.tar server2:/path/to/destination/dir
(b) from server2 to server1:
rsync -avP -z -e server1:'/path/to/*.tar' /path/to/destination/dir
Notes:
* Use either (a) or (b) but not both
* Remove the -z flag if your files are already compressed
* Set up ssh certificates to ensure you don't need to provide
a password. If you don't know how to do that, read up ssh-keygen
and then ask here again if you're still stuck.
* If your remote user account is different to the local one, prefix
the remote hostname with "user@", where "user" is the remote
username.
* rsync only copies changes, so it's (reasonably) efficient to
call it even when there have been no changes to the source
data files
