RISK

Why cloud_backup_update is rated Medium

This tool creates or modifies data reversibly by updating backup task configuration. While it has side effects (changing backup behavior), it is not destructive (data/configs can be reverted) and does not execute arbitrary code or move money. The 'high' severity reflects that misconfiguring cloud backups could compromise data protection strategy, affecting backup integrity and disaster recovery capabilities.

From the tool's definition Tool name is 'cloud_backup_update' and description states 'Update an existing cloud backup task' — this modifies configuration of a backup task reversibly without deleting it.
