Hello,

As the Spaces are object storages, I would suggest using a tool like s3cmd. Here’s how you could set it up:

And then once you have it configured, you could take a look at this article on how to use it:

As a side note, for backups, I would also recommend just enabling the droplet backups provided by DigitalOcean.

Hope that this helps!
Regards,
Bobby
