    Are you mixing up lzo with zlib (gzip) ?

    lz4 doesn't fare that bad against lzo (lzop), and yes, in some cases the compression ratio is slightly worse

    For me the ease of use of:

    - snapshot handling (sending and resuming [git pull] them), handling of clones [git pull], rolling back of snapshots
    - ditto blocks (having several copies of one file "mirrored" on one disk)

    are its pros, the more I use the more I

    learn to cherish its other advantages/features (see wikipedia) and:
    - COW/atomic character (on each hardlock, crash, etc. so far the data integrity was preserved)
    - data-integrity preserving characteristics and the intelligence behind scrub or automagic data error fixing (in mirror operation; already caught several hardware issues and thus saved my data, before it was eaten or destroyed/modified)
    - lz4 compression and relatively efficient data storage (several hundred MiB or GiB less than compared to Btrfs; lzo vs. lz4 shouldn't be the cause so not sure why)
    That's kind of an odd result, if i understand your point. Lz4 should have a worse compression ratio than zlib, in general, but be a good deal faster.
