Or you may be charged for additional storage, depending on the service. If you have a terabyte of files on a service where 1TB is the storage limit, older files might be deleted more quickly as you add new files.

We’ve listed some of the more popular, easy-to-use, and convenient ones below. So make sure to store the passphrase somewhere safe, like a password manager. But if you lose your passphrase for that key, you’ve lost access to all your backup data, and the service won’t be able to help. If you're storing sensitive data, you may want to choose a service that lets you use your own encryption key so the data isn’t accessible if the cloud provider has a data breach. “Make sure that the vendor you’re choosing has a backup recovery time that is appropriate for you,” says Dominique West, technical account manager at the cloud monitoring service Datadog.
