Use the Backblaze B2 storage option when your Duplicacy version exposes it.
Steps for Windows
- Create or select a B2 bucket in your Backblaze account.
- Create an application key with the minimum needed bucket access.
- In Duplicacy Storage choose B2 and enter the required bucket and key values.
- Run a small encrypted backup and test restore.
How to verify the result
The expected object data appears in the chosen bucket and the test file restores.
Do not post application keys or storage-encryption passwords in support screenshots.
Why this matters
The practical goal is a recoverable Duplicacy revision, not just a successful-looking progress indicator. Keep your source, backup destination, Backup ID and necessary credentials documented. If this workflow changes your retention or storage configuration, verify a restore before applying it to important data.
