Backblaze B2: a key for BackupWitness
List-only keyA list-only key needs the B2 command line tool; the web console offers read-only keys, which most likely include reading files.
Steps
Create a key restricted to the bucket with only the listFiles capability:
b2 key create --bucket YOUR-BUCKET [--name-prefix backups/] backupwitness listFilesUse the printed keyID as access key ID and the applicationKey as secret; it is shown once.
Without the CLI: Application Keys, Add a New Application Key, Read Only, limited to the bucket. Expect that key to be able to read files too.
In the check form
- Endpoint:
https://s3.<region>.backblazeb2.com- Region:
- The region from the bucket endpoint, for example us-west-004.
- The master application key does not work with the S3 API.
- If the key has a name prefix, enter the same prefix (or a longer one) in the check.
