[Leaplist] Go back machine for EXT3

[patrick]

Ext3cow is an open-source, versioning file system based on ext3.  It
provides a time-shifting interface that allows a real-time and
continuous view of the past.  This allows users to access their file
system as it appeared at any point in time.  Click here for a usage example.

Ext3cow was designed as a platform for regulatory compliance, and has
been used to implement secure deletion, authenticated encryption, and
incremental authentication. See the publications page for more details.

Some advantages of ext3cow:

   1.
      • It does not pollute the name space with named versions
   2.
      • It has low storage and performance overhead
   3.
      • It is totally modular, requiring no changes to kernel or VFS
interfaces
