Support for AWS, Backblaze and Wasabi S3 cloud storage
Directly uploading from tape or downloading to tape is not recommended.
Any bandwidth limitations will cause the tape drive to over or under-run.
Use local storage and create two jobs on YoYotta

Backblaze Buckets created prior to May 4th, 2020 are not S3 Compatible.
Requires YoYotta Server subscription and a YoYotta Mac license running v3 (166) or newer

Secure storage of S3 access keys

Manage S3 access keys

Log in to the YoYotta Server as an admin user.
Then select Admin, Objects in the sidebar.
All the S3 access keys will be listed.


Add a new key

Enter a name as a reference
Enter the access and secret keys.
For Backblaze and Wasabi enter the bucket endpoint. This is not needed for AWS S3 storage.


Activate required keys

There are two ways to toggle the key's Active flag.

  • Alt click in the cell
  • Select the cell and click the edit button in the table toolbar

The YoYotta Mac client has to log into the server and will only see active keys.
Keys are secure, as they are never stored and cannot be viewed on the Mac.
