Have tried a few over the years.When I have needed the image to fix things it has some how got corrupted or.................

So have given that type of software away and make sure I have copied letters or downloaded software etc that I can not afford to lose and that I know is working etc to two external USB drives and a hard drive on another PC with a synchronization program.

Software can be re-installed. But things I can not afford to lose I need to make sure I have got a copy of.
