Backblaze B2

Backblaze B2 is inexpensive and works through its S3-compatible endpoint.

1. Set up the storage

  1. Sign in to Backblaze and open B2 Cloud Storage.
  2. Create a Bucket - set it Private.
  3. Open Application Keys > Add a New Application Key. Restrict it to the bucket you just made, with read and write access.
  4. Copy the keyID and the applicationKey (shown once).
  5. Note the bucket’s S3 endpoint, shown on the bucket details - for example s3.us-west-004.backblazeb2.com.

2. Connect it in Nyx Backup

New backup set > destination Backblaze B2, then enter:

  • Bucket - the bucket name.
  • Key ID and Application key - from step 4.
  • Endpoint / Region - use the bucket’s S3 endpoint or region from step 5 if prompted.

Once Test connection succeeds, set a schedule and retention, save the set, and choose Run now. Nyx Backup encrypts everything on your machine before upload, so this destination only ever holds encrypted blobs. Give each machine its own bucket or folder - see Connecting storage.

Tip: create a key scoped to the single bucket rather than a master application key.
