Adding Backblaze B2 storage as a backup destination

To send backups to Backblaze B2 storage, you first need to set up a destination in the “Storages” page:

Where to get Key ID and Application Key?

 

The Application Key to your Backblaze B2 storage cannot be retrieved from you Backblaze account once it has been created. If you did not store it when it was first generated, you will need to create a new Application Key.

2. In the left-hand menu, navigate to Application Keys under the Buckets section.

3. Click the “Add a New Application Key” button and fill in the required information:

4. Click “Create New Key”.

⚠️ Important: After creation, make sure to copy and securely store the Key ID and Application Key, as the Application Key will not be shown again once you leave the page.
