Configuring Backblaze B2
Set up Backblaze B2 as an S3-compatible storage destination.
4 min readStorage
Backblaze B2 offers very low storage costs ($0.006/GB/month) and is S3-compatible via the B2 Native API.
Step 1 — Create a bucket
In Backblaze → B2 Cloud Storage → Create a Bucket. Set it to Private. Note the bucket name and the endpoint (e.g. s3.us-west-004.backblazeb2.com).
Step 2 — Create an application key
In B2 → App Keys → Add a New Application Key. Restrict it to your specific bucket, and grant Read and Write capabilities.
Copy the Application Key immediately — it's shown only once.
Step 3 — Add to VPS Snaps
In Storage → Add Destination, select S3-Compatible and fill in: bucket name, region (your region string, e.g. us-west-004), keyID as the Access Key, applicationKey as the Secret Key, and the S3-compatible endpoint URL.
