I think Daniel was trying to say, cpu might not be the bottleneck, it could be network or something else (I doubt it's memory rsync 3 pretty much solved that for most) and if you ask me it's probably disk. If you're not using different partitions on different disks, then doing anything in parallel is probably going to slow it down (reading/writing all over the disk, means more seektime, which means waiting). Otherwise, if it's seperate disks, why not start several, possible with -x option, which will confine it to one partition. >>> I have 4 cores available >> It seems good :) > > But how can I make rsync use all 4 cores? :) > >> Rsync can backup only differs.
