Before you start: log in to the client area, open your S3 Cloud Storage service and note the S3 endpoint, access key and secret key (click Reveal secret key). Create a bucket first in the web console at clouddrive.altnhosting.com.
Install rclone from rclone.org, then run rclone config and create a remote:
[altn] type = s3 provider = Other access_key_id = YOUR_ACCESS_KEY secret_access_key = YOUR_SECRET_KEY endpoint = YOUR_S3_ENDPOINT acl = private
Test it with rclone lsd altn:, then back up a folder:
rclone sync /var/backups altn:company-backups/server1 --progress
Add the command to cron to run it every night. The same details work in Cyberduck, AWS CLI (--endpoint-url), Restic and other S3 tools.
