I need a remote backup service that doesn't require syncing (i.e., Dropbox, iDrive). I've been using USB drives to archive files but I need a remote location to store them (currently safe deposit box). The remote backup location would be an ideal replacement for these USB drives.
One other thing the service needs is a way to recognize if I have already backed up a file into a specific folder. I don't want to upload a 2GB file that is already in the same location.
After files have been backed up, I will remove them from my local hard drive. That is why syncing shouldn't be a requirement.
Does anyone have a suggestion like this?
