I just want to back up my JPGs to the cloud - what solution?

Another option is to roll your own cloud.

If you have a friend, family member or business location you can attach an external drive to one of their computers or put an old computer or laptop of your own on their location and run Tonido's software. It works great. Or you can purchase their small unit that accepts any 2.5" drive. All it needs is a wall outlet and an ethernet/lan connection or wifi.

The plus side is you can seed the backup from your home and get the initial large backup done quickly. Then move the drive to the remote location, your backups over the internet will go much faster.

Options, too many.
