Bear in mind that many of those who are interested in ZFS are interested in it specifically because they care a lot about <i>not losing data</i>.<p>With that in mind, let&#x27;s see what the btrfs wiki has to say about the stability of btrfs:<p>&quot;Is btrfs stable? Short answer: Maybe.&quot;<p><a href="https:&#x2F;&#x2F;btrfs.wiki.kernel.org&#x2F;index.php&#x2F;FAQ#Is_btrfs_stable.3F" rel="nofollow">https:&#x2F;&#x2F;btrfs.wiki.kernel.org&#x2F;index.php&#x2F;FAQ#Is_btrfs_stable....</a><p>Maybe it&#x27;s just me, but I&#x27;m more than a little concerned by the fact that btrfs has been in development for over 8 years and still doesn&#x27;t seem to be considered safe to use for storing anything I really care about.
