+BTRFS
+=====
+
+Btrfs is a copy on write filesystem for Linux aimed at implementing advanced
+features while focusing on fault tolerance, repair and easy administration.
+Jointly developed by several companies, licensed under the GPL and open for
+contribution from anyone.
+
+The main Btrfs features include:
+
+    * Extent based file storage (2^64 max file size)
+    * Space efficient packing of small files
+    * Space efficient indexed directories
+    * Dynamic inode allocation
+    * Writable snapshots
+    * Subvolumes (separate internal filesystem roots)
+    * Object level mirroring and striping
+    * Checksums on data and metadata (multiple algorithms available)
+    * Compression (multiple algorithms available)
+    * Reflink, deduplication
+    * Scrub (on-line checksum verification)
+    * Hierarchical quota groups (subvolume and snapshot support)
+    * Integrated multiple device support, with several raid algorithms
+    * Offline filesystem check
+    * Efficient incremental backup and FS mirroring (send/receive)
+    * Trim/discard
+    * Online filesystem defragmentation
+    * Swapfile support
+    * Zoned mode
+    * Read/write metadata verification
+    * Online resize (shrink, grow)
