This function deletes the named website backups, removing each archive and its sidecar manifest.

Note:

• This is a synchronous delete. It starts no operation and nothing needs polling.
• The call returns one row per requested id rather than failing as a whole, so a partially successful batch reports each outcome individually.
• The call itself fails only when the whole batch is unusable, meaning the ids parameter carried no non-empty value at all.
• This function returns an array, so UAPI's generic api.filter_*, api.sort_* and api.paginate_* parameters apply, and a caller-supplied sort replaces the default ordering of the data return value.
• This function requires the account's backup feature and is unavailable to demo (shared) accounts.
