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.
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:
