I am on Win7 SP1 on my Lenovo E535 laptop and am considering updating my backing up activity. The machine offers the standard M$ system which is more or less OK. Lenovo also offer a BU system but i have not delved into it as yet. It is my long term goal to exit M$ and go Linux. Would it be advisable to go over to the alternative scheme now so that a seamless drill can proceed? I have not heard any comments on the performance when using Lenovo stuff. I have two external HDs, one (SATA) big enough to absorb the whole of the main HD and a smaller one suitable for taking the personal stuff all on USB2. I also have a few 16GB USB DataTravellers.now Thanks in advance.
