I am having the same problem. I am backing up 30 GB worth of data. It is currently backing up at a rate of 100-200MB per hour. I estimate I have 1-2 weeks left to backup the last 8 GB of my backup. When I started, it appeared it would take about 8 hours from the estimates I made.

Buffalo LinkStation LS-WTGL/R1 per the manual
NAS Navigator calls out:LS-W2.0TGL/R1-V3
Firmware 3.09
Computer:

Pentium 4 CPU 3.00 GHz, 2.5 GB RAM
Windows XP SP3 Media Center Edition Version 2002
