Integrations
S3-compatible storage
Connect any S3-compatible bucket as a backup destination — AWS S3, Backblaze B2, Cloudflare R2, MinIO, Wasabi, and others.
1
Open Preferences → Accounts
In Tusk, open Tusk → Preferences (or press ⌘,) and navigate to the Accounts tab.
2
Add an S3 destination
Click Add S3 destination. A form appears with four fields: endpoint URL, bucket name, access key, and secret key.
3
Fill in your credentials
Enter the credentials from your storage provider. See the provider reference below if you're unsure where to find these.
4
Test and save
Click Test connection. Tusk sends a test request to verify the credentials and bucket access. If the test passes, click Save. The bucket appears as an available destination in your projects.
Provider reference
AWS S3
Use your bucket's region endpoint, e.g. s3.us-east-1.amazonaws.com
s3.amazonaws.comBackblaze B2
Use the S3-compatible endpoint from your B2 bucket settings, not the native B2 API URL
s3.us-west-004.backblazeb2.comCloudflare R2
Find your endpoint in the R2 dashboard under your bucket
<account-id>.r2.cloudflarestorage.comMinIO
Use the host and port of your MinIO instance
your-minio-host:9000Credentials and security
Use an IAM user or API key with the minimum permissions required: s3:PutObject, s3:GetObject, and s3:ListBucket. Tusk stores credentials in your macOS Keychain — they are never sent to Tusk's servers.
