I was wondering if this product allows the following backup scenario:
The user's hard drive is becoming full with photos and other things. She wishes to backup her documents to the backup drive to save all this material and then have the freedom to free files from her hard drive without affecting her backup drive. Then when more files are added to her hard drive she can back them up to the backup drive by manually running this product, resolving any possible file name conflicts. In other words her backup drive will contain more files than her hard drive. There will be a second drive that will mirror her backup drive for safety and redundancy.
Additionally is there something that can guarantee not using her mirrored drive as her backup drive? Please keep in mind that this user is not particularly computer savvy.
Thanks!
