What's the best way to do this?
Daily, jpg images are added to an inhouse server. Everynight I want to backup these images to a server offsite, via rsync. What I want is to determine what to set the bwlimit to. I also want to estimate how many MB's of images I can move nightly. Thanks Dan

If you need the bandwidth for other purposes at night you could set the bwlimit to half to three quarters of the available bandwidth, and the rest will be available for other uses like dns servers and such. Using compression ( the -z option) probably won't help with jpg's.

Iperf is great, I think I've managed to sustain 990Mbit/s between a pair of linux servers on the same GigE switch with no tuning. Of course when doing file transfers, local I/O subsystems limited the transfer to about 250-300Mbit(pair of 7200RPM SATA disks on each end).
