Hi,

  This patch added autosnap feature for the btrfs-progs.
  The link below provides autosnap guide..

     http://btrfs.ipv5.de/index.php?title=Autosnap:_Configure_your_btrfs_to_create_and_manage_snapshots_automatically_based_on_events_or_at_a_regular_frequency

  Further there is timeslider, a nautilus extension written
  in python which can be downloaded from

     git://github.com/asj/timeslider.git

  Pls follow README and install.sh for the installation of
  the same.

  Further kindly note that as of now there are some limitation
  and known bug which is documented in the above autosnap wiki
  guide.

  Appreciate any feedback.

Thanks, Anand
