This is partially right. In most cases data is only highly sensitive for a
limited time - the need for security often "ages" with the data.
Re-encrypting is no use if the intruder has access to the backups with the
old versions with the less secure cryptography.

The principle is to get as secure as viable with reasonable effort.
