Most services encrypt your files with strong systems such as AES 256 before sending them up to the servers over an encrypted connection. The majority of products we tested also offer a private encryption key option. If you choose to manage your own encryption keys (basically the "key" that decrypts your backup), know that it is your responsibility to remember it. The online backup service itself will not be able to help you reset the password if you forget it. On the flip side, this means that no one (including employees of the backup service and law enforcement officials) other than you can unlock your backups. This is ideal from a privacy and security standpoint. Use a password manager to keep track of your private encryption key if you think you will forget it.
Some services go above and beyond, including extra capabilities that improve the experience. For example, a few offer disk courier services for bulk uploads and restores via an external drive that the company ships and manages. A couple of these services throw in a local backup component, too. If you go that route, you should take a look at our roundup of best external hard drives. Some of these services can even track your device's location and let you remotely wipe it in case it's lost or stolen.
When you’re looking for something to watch or listen to you want something that you’re going to enjoy, but you also want a good amount of value. With downloading an entire YouTube channel, you’re not going to have to worry about that because you’ll be able to check back in on a number of different videos and different episodes that you may or may not have seen before. This also gives you a whole lot more freedom to check out something different without having to worry about downloading yet another episode or video that you don’t have the data for.
The cheapest of these plans is $8.33 /month for 1 TB of backup space and support for 10 devices (and three sub accounts), if you pay for a whole year at once. You can add more for the same price and storage, like another 1 TB for another $10 /month. The maximum storage plan you can pay for is 15 TB, but if you want more you can contact their support team.
