I wonder whether there is something wrong with your setup,
particularly on the Windows machine.
I backup a WinXP Home partition containing 110,000+ files totaling
just under 27GB (i.e. about 3x as many files as you consuming a little
more diskspace)
The client is low-end, *old*, and slow -- 4+ year old, single core
celeron 1.6GHz with 2GB ram. The server is non-dedicated and even
older - 8 year old, Pentium4 non-hyper threaded, single core, 2.8GHz
with 3GB memory. The network connection is a shared Linksys wireless G
router. Storage is via NFS over a 100mbps wired port on the Linksys
to a low-end consumer NAS (DNS-323). Clearly, my hardware is about as
old and low-end as one can get ;) I use rsyncd with cygwin 1.5 (or
1.7) with a stock BackupPC install.
Yet, incremental backups take about 15-20 min and fulls take about 70
minutes. So unless you are changing a large fraction of the files and
disc space between fulls, I would suggest that there is a problem with
your setup.
