Did anyone else bothered to backup recently after mac was updated to 10.7.5? It took 3 hrs to backup 3.2 GB worse of changes made by update. I am using FW800/FW400 both are dreadfully slow. Another forum folks mentioned, network backups are extremely slow as well. Drives and FW is not a problem. I could copy files at max throughput. Time Machine idles 99% of the time, only occasionally dumps ~20MB worse of data and idles again.
