Something wrong. I get 1GB/min to USB on average, making System Images.
Network is slower. 100Mbits/s. I don't backup over the network usually, but I am gonna do it later, just made a fresh image on PC upstairs to its own partition. Need to get it downstairs onto my ext HDD. (Ethernet cable). Doesn't take 16 hrs though.
Worst case for you, burn 3 x DVDs for 12GB?
It does files and folders as well as Images now. Note: You cannot restore an old machine Image to a new one. But you can 'Mount' the image and browse it.
Handy when you forget about hidden files somewhere on the old system.
