I think In Dale's use case compression is a solution seeking to address the
problem of not enough storage space for backups, but it only makes sense if
the data can be effectively and efficiently compressed. He mentioned 99.99%
of his backup data is video. Video files are not particularly compressible,
although small space savings can be achieved. For example using basic enough
zst parameters '-19 --rsyncable -z' I got just a 1.6% file reduction:

1 0 88.9 MiB 90.3 MiB 1.016 XXH64
Even if compression delivers some small space saving, given Dale's new faster
Internet link and local video storage tendencies, compression will only kick
the can down the road. If these are not private or rare videos and remain
available on public streaming platforms, perhaps local storage is no longer
necessary?
