Hello All,
I am a CS graduate student from Carnegie Mellon University. I am
hoping to build the feature - Content based storage mode under
Google Summer of Code 2015. This project has also been listed as an
idea on BTRFS ideas page. However, I have not found a mentor yet, and
without a mentor I

Read further, Sun did provide a way to enable the compare step by using
verify instead of on:

I have tested ZFS deduplication on the same data set that I'm using to
test btrfs.

It is always interesting to compare this to the rate you would get
with old fashioned compression to see

Some years ago I was searching for that kind of functionality and found
an experimental ext3 patch to allow the so-called COW-links:

I'd read about the COW patches for ext3 before. While there is

The basic idea, as I understand

Hi,
just want to add one correction to your thoughts:
Storage is not cheap if you think about enterprise storage on a SAN,

Hi,
I was wondering if there has been any thought or progress in
content-based storage for btrfs beyond the suggestion in the Project
ideas wiki page?
The basic idea, as I understand it, is that a longer data extent
checksum is used (long enough to make collisions unrealistic), and merge
on Hard Disk and make SSD
devices possible for storage (because of the space efficiency).
