Every night, here, there is a sync/backup over the network between 2 USB drives (both connected to a different AP which are connected by UTP (cat5)) with:
rsync -av --delete /tmp/mnt/USB1/ -e "ssh -i /opt/usr/authorized_keys/id_rsa" 192.168.5.9:/tmp/mnt/USB2/
This is running at about 1,1MB/s. That's not much, but the data changes aren't huge, say between 0-2gb. I decided to lower the security (as the backup is done within the LAN, security is not a real issue) and I changed the above line to:
rsync -av --delete /tmp/mnt/USB1/ --rsh="ssh -i /opt/usr/authorized_keys/id_rsa" 192.168.5.9:/tmp/mnt/USB2/
This gave an increase of about 36% to 1,5 MB/s.
With a simple "cp" I reached speeds around 5 MB/s. Maybe I should check where the bottle neck is with a tool like "iperf" ? If someone has any idea thanks in advance
