Several backup tools have encryption in place so that your data can be encrypted before it leaves your device. Rclone for example has encryption and Backblaze B2 capability.

I looked at rclone once and didn’t find any information about encryption. Thanks for mentioning it

Crypt will encrypt all files before they leave your device, yes.

To the non-rclone users, this refers to one of the targets of rclone; the crypt backend wraps the real backend by chaining them together, e.g. localdata <=> crypt <=> providerstorage (basically like a bi-directional filter). https://rclone.org/crypt/

Edit: I use rclone as the backend for duplicity, so you can also chain it through another tool with different encryption and use rclone as just the transfer engine, getting all the benefits of rclone's providers with the benefits of duplicity's backup strategies.
