When using data-at-rest encryption, compressing the backup stream is useless. Compression will not find any mathematical redundancy in the data stream. Encryption is immune to compression.
In order to achieve proper compression and encryption, you must compress then cipher. And decipher then decompress to read the data.
The current openssl example above is right on.
