[Tux3] Data Deduplication in Userspace : http://www.lessfs.com

[Mark Ruijter]

Hi,

I saw your post on Tux3,
It might be nice to know that a high performance GPL data dedup
filesystem already exists. It offers good performance and compression
See : http://www.lessfs.com or http://sourceforge.net/projects/lessfs/
for more information.

Mark.

> code with data deduplication in userspace can be downloaded/ cloned from http://bitbucket.org/kushal/tux3_dedup/ . 
> The code uses the openssl SHA1 implementation and requires openssl libs to be installed.
> The dleaf part of the tux3graph output after copying the same file twice with and without deduplication are also attached along with the patch. 
> Keeping in mind archival storage as the main application of deduplication edits and deletes have not been implemented yet.
