====== 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.
