Can anybody suggest me a good, free software to back-up my files on Win7. I need to back-up files to an external HDD. Also it would be good if it had the functionality to do incremental back-ups. It would also be good if it could be run from a USB stick, but that is not absolutely essential. Thanks for any suggestions. P.S Also please don't suggest the default windows back-up tool. I'm mainly asking because that one doesn't work. Long story short the System reserve partition doesn't have enough free space to execute the back-up tool(great work with this Microsoft). Tried a few of the simpler solutions that the inet provided, but none worked. The only thing left to try is to make that partition larger, but I don't feel like messing with that at the moment.
