If you are searching for an alternative for Backblaze Backup. You can try rclone with s3 storage from Scaleway.

In these Blogpost you can find out how to install and configure it. But how to use it? I have some example for you.

https://www.scaleway.com/en/docs/tutorials/encrypt-s3-data-rclone/

https://www.scaleway.com/en/docs/storage/object/api-cli/installing-rclone/

Thats for a Windows machine, on Linux only other path K:test = /home/ubuntu/myfiles

rclone sync --progress K:\test Scaleway:allmybackup

If you want to store your data directly in to the GLACIER storage you can use

rclone sync --progress --s3-storage-class=GLACIER K:\test Scaleway:allmybackup

or you can configre rclone directly to use GLACIER directy without define storage class

Simple example if you are using encryption with rclone

rclone sync --progress K:\test crypt:

Now we have more options for bandwith usage

Attention rclone is using Megabyte not Megabit 1M are 8Mbit

rclone sync --progress --log-file=rclone_log.txt --bwlimit "06:00,2M 23:00,4M" K:\test crypt:
