It would likely increase the latency, but it should not significantly
impact the required bandwidth, assuming that you have a full-duplex
connection. If you have a half-duplex connection, yes, the bandwidth
consumption would double.

Yes , with single network adapter.

We using segmented network layout 
aka own network-interface for production, management and backup
so bandwidth is not a problem for copying.

Cause server are also configured own VLANs and firewalls between
segments blocking traffic and eating performance so remote-remote
rsync sounds good and gives more ways to copying data easily to
server to server example in hardware refreshing cases.

Moin,

this is something for the wish list: a 'rsync in the middle' mode. It
would make sense: rsync is running at a server. Copyying files from  
one

maschine to a file server.
rsync r...@client:/var/tmp/in tom...@fileserver:/opt/

Would this be possible without breaking the hard link mechanism?

It would however be quite useful in some situations...

I stand corrected and further educated. (And I really should get a  
better connection...)


Great list!
