Data backup software is also about recovery and accessibility. If you loose some data and have the best backup software running, you are very dependent upon its recovery options to actually save your data. Backup solutions on the internet all (almost) have multiple ways of recovering you software and the only requirement is an internet connection and probably access to your email (for password recovery and acceptance). This post is not about a selection of 3 backup programs but more a general proposal for you looking into the options yourself. You can easily get a picture of the benefits the different vendors have to offer you. I strongly recommend using an internet backup service instead of ordinary windows backup programs.
