Rules

You can apply rules to the data that is in your Backblaze B2 Cloud Storage account.

The Cross-Origin Resource Sharing (CORS) rule lets you lift the restrictions that web browsers may have that limit a web page's access to content from other sites.

You can use Lifecycle Rules to automatically hide and delete old files.

Object Lock lets you make data immutable by preventing a file from being changed or deleted until a given date to protect data that is stored in Backblaze B2.
