I had the same issue with backups running slowly over rsync from windows hosts. The problem started after I upgraded cygwin to 1.7 in order to support long file names. On each workstation I'd been getting 80% utilization of a 100Mbit network card. After cygwin 1.7 I was only getting 8%.
I compiled a newer version of 1.7 and its back up to 80%. Or you can try 1.5 to see if that's your issue without going through the trouble of compiling your own... but no more long file names of course.

If I were to speculate about a "culprit" for rsync's poor performance relevant to smb, I'd suggest that it's the many layers sitting between rsync and the Windows' file API. > Tino Schwarze wrote: > Most of the people using backuppc are probably linux oriented so bad > performance on windows is just expected, and compensated for by running > more instances concurrently if the server is waiting.
