I use rsync to backup my N2100 to a USB attached drive but rsync is very slow (as commented in various places).
I did some quick tests and rsync runs about 8-12 times slower than CP giving speeds of about 2.5MBps. This is not far off USB1 speeds and much slower than the 25MBps I was hoping for.
I've searched various forums and the issue seems to be SSH and the fact that it is encrypting everything even for local drive - local drive copies.
Can anything be done to fix this ? I've seen posts where you can tell SSH to use a quicker cypher such as blowfish instead of the default 3des but when I tried the suggested command it made no difference.
rsync -e 'ssh -c blowfish -ax' -v -a {source} {dest}
Is it possible to tell ssh to not encrypt for local traffic (I'm guessing no, as not encrypting is an alien concept to ssh) or to get it to use a faster cypher ?
Failing that is there anything else out there like rsync that does intelligent file copying but which doesnt run over SSH ?
