The first thing you have to do is to take a market survey among 4-5 potential virtual backup firms. The market survey will help in coming up with a good comparative study on the different backup firms enabling an informed choice on your part. Follow the expert reviews on the companies, their client testimonials and service approach. It’s needless to mention that your selected one should be the most reputed of the lot, backed by great ratings from experts and a very happy clientele.
Another important point to look for is whether your chosen virtual backup company allows for automatic data backup. The automatic backup facility will ensure that your remote data is updated perfectly as per your local folder- you may well forget to update the remote data every time you make changes in the local folders which can be dangerous in case anything bad happens to the local folder. Finally, the virtual backup company should promise secure online backup with military grade encryption effect on your virtual data.
