WHAT IT DOES

What gcnv_backup_restore_files does on Google Cloud NetApp Volumes MCP Server

WHY IT NEEDS A POLICY

Why gcnv_backup_restore_files needs a policy

Restoring files from a backup writes data into a destination volume. This is a Write operation as it creates/overwrites files in the destination. However, it carries high severity because it could overwrite existing data in the destination volume — though it targets specific files rather than doing a full volume restore, it could still cause data loss in the destination if files are overwritten.
