No, the script contains no separate compression step during encryption.
But there is a separate decompression setp on recovery.
It is done before decryption.
Because of this I assume that the builtin gpg compression is done after
encryption. Thus my comments suggesting a compression step be added
before pgp encryption and reversal of the pipeline on recovery.
