First of all, is there something wrong with your hard drive? If not, I would think there are better tools for this job than ddrescue.
if you're still going with ddrescue, perhaps you can export a drive using iSCSI from the target server, and make that available as a block device on the source server. Then you can run ddrescue to copy directly from the source drive to the target iSCSI drive, and let the iSCSI layer handle the network transfer. I've never tried, but I guess it should work fine.
