Romi,
Hi. It's difficult to tell if there are any other issues as we don't have enough information. Part of it depends on your simultaneous backup. What hard drive? Is it external or on the same computer, etc. From what you are saying so far, I don't think you have enough redundancy to go paperless.
Sooner than you think your scanned files are going to become 5GBs are more, and you will not be able to back them up off site. Now, you have only one backup.
