Debian Is Still Working To Land ZFS On Linux Support

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

It's not really an alternative to ext4 since it was built with completely different goals in mind, it's more of an alternative to Btrfs since that provides similar features

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.

So what are the preminent features of this file system? it operates as an alternative to 4ext!?

Debian is still working to add a ZFS kernel module to the Debian GNU/Linux repository...
