> Btrfs also supports transparent file compression. There are three algorithms available: ZLIB, LZO and ZSTD (since v4.14). Basically, compression is on a file by file basis. You can have a single btrfs mount point that has some files that are uncompressed, some that are compressed with LZO, some with ZLIB, for instance (though you may not want it that way, it is supported). https://btrfs.wiki.kernel.org/index.php/Compression https://btrfs.wiki.kernel.org/index.php/Compression
