gzip with the —rsyncable flag will still allow for deduplication. It uses a content-aware rolling checksum and resets the compression dictionary whenever that checksum has a certain number of zeros.
The result is a valid gzip file with a few percent less compression, but friendly to deduplication (which is what rsync does).

Good point. I'll stay away from cheesing up my commands and wait for it to be built in.

What is "cheesing up"?

It's what Google speech-to-text thinks I meant when I said "gzip" into my phone.
If it does compression, then it's not an opaque process to it. But if you do it, you are essentially obfuscating the structure of the data.
