 ====== BTRFS deduplication ======
+===== Deduplication =====
+External tool to find duplicated extens available
+[[https://github.com/markfasheh/duperemove]]
+Simply do 'make' and 'make install'
+Following binaries will be installed:
+  * btrfs-extent-same
+  * csum-test
+  * duperemove
+  * hashstats
+  * show-shared-extents
+Recursively find duplicates in <dir>
+<code>duperemove -r <dir></code>
+The same as above, but make real deduplication (on BTRFS only)
+<code>duperemove -rd <dir></code>
+Increase deduplication chance by reducing block size to 4k:
+<code>duperemove -b 4k -rd <dir></code>
+This deduplication works nice, it can find some shared parts inside Maildir.
