WHAT IT DOES

WHY IT NEEDS A POLICY

Why cloudron_backup_app needs a policy

Creating a backup modifies system state by adding new backup artifacts, making it a Write operation rather than Read (it has side effects). It is not Destructive because backups are additive and don't irreversibly delete data. It is not Execute because the operation itself is a standard administrative action with predictable effects, not arbitrary code execution.

From the tool's definition Tool name includes 'backup' and description states 'Create a backup of a specific application' — these are reversible write operations that create new data/artifacts without deleting or overwriting existing resources.
