Add Wasabi/Backblaze

Hi,

Thanks for contacting us here about this extension.

Please add Wasabi or Backblaze. Amazon is really expensive

We are integrated with Amazon currently. Wasabi's policy no longer supports Public buckets.
Please go here for further information.

Anyways, I'll add Backblaze integration to our feature request list and keep that in mind for a future release.

Thanks a lot!
Cheers,
