Everyone has different needs and I encourage each person to find a solution that works best for them. For me, using the TrueNAS GUI with the rclone backend didn’t work well for me. It didn’t offer the flexibility I needed for my backups to AWS Glacier and Deep Archive. When I set up the CloudSync task, the rclone backend insisted on uploading the 46TB that were already in AWS’ cloud. I understand that rclone has some tricky behavior when using AWS Glacier and Deep Archive storage tiers. In the end I ended up installing the latest version of AWS CLI. I use the native AWS CLI, some scripts, and systemd timers to automatically backup my TrueNAS arrays to AWS as an offsite backup solution. Good luck with finding the right solution for you!
