InterBack

From Edge Publishing:

Use InterBack to backup selected directories or specific files across the Internet to a remote site of your choice. InterBack will compress your files, encrypt them, and transfer them over your internet connection automatically at a time that you have chosen. InterBack uses standard zip compression to compress files to less than half their original size. The compressed file(s) can then be encrypted using DES encryption (US or Canada only) or using the Ruby 5 encryption algorithm (International version). The files can then be transfered to any Internet ftp site that the user has an account on. Events are automated to run at any pre-selected time. At the end of the file transfer, the user can be notified by email on the success of the event.
