Congratulations on creating a backup! Good news is there is a lot of documentation on this, plus an rclone community forum. Other have discussed rclone backups on this forum as well.
Other discussions about this mention scripting bash backup and restore – see this active thread.
A simple tool you could use alongside rclone is restic, which is explained in detail by @Reiner_Nippes. Seems it will help you add scheduling, pruning, and encryption to your rclone backups. Looks useful!
