   btrfs is not a filesystem in the ext family.  It is developed at   
   Oracle, and if anything, it is much more akin to ZFS, albeit that the   
   RAID-5/6 functionality of btrfs is still not usable.  The on-disk   
   format has however already long been stable and it is quite resilient.     
      
   I've been using btrfs here on my production machine for over two years   
   already — I do use ext4 for /boot because GRUB doesn't like btrfs   
   (although there is a patched version that does) — and I haven't had any   
   problems with it so far. It didn't even budge after two unexpected power   
   failures. Earlier I had been using XFS, with which I wasn't so lucky   
   under those very same circumstances.   
      
   Some of the advantages — for more information, check the Wikipedia page   
   or the man page...:   
      
    ° Copy-on-write.   
      
    ° Supports transparent inline compression and will autodetect the   
      compression type and compression factor.   
      
    ° Autodetects whether it's running off of an SSD, and if so, will   
      automatically enable performance optimizations for SSDs.   
      
    ° Snapshots.   
      
    ° Subvolumes.  Think of them as separate partitions, except that the   
      free disk pace is shared among all the subvolumes.  Subvolumes are   
      however not regarded as separate block devices.   
      
    ° Multiple root directories per filesystem, so that you can mount a   
      different subvolume as the root volume of the partition.   
      
    ° Has an auto-defragmentation mount option — should only be used on   
      spinning rust disks, of course.   
      
    ° Supports swap files for those who don't want to use a swap partition.   
      
    ° Supports RAID-0 and RAID-1.   
      
    ° Data AND metadata journaling.  The journal is always replayed after   
      an unclean shutdown, even for read-only filesystems.   
      
    ° Allows for rebalancing the trees after lots of moving files between   
      individual subvolumes.   
      
    ° Excellent documentation.
