zfs discuss - Oct 2009 - PSARC 2009/571: ZFS deduplication properties

I haven''t seen any mention of it in this forum yet, so FWIW you might
be interested in the details of ZFS deduplication mentioned in this
recently-filed case.

Very nice -- I like the interaction with "copies", and (like a few
others) I think the default threshold could be much lower.  Like *many* others, 
I look forward to trying it out.  =-)

Also see PSARC 2009/557 for a separate dedup capability within "zfs
send".

Anyone know if this means that this will actually show up in SNV soon, or
whether it will make 2010.02?  (on disk dedup specifically)

It will go in when it goes in. If you have a support contract call up  
Sun and ask for details; if you''re using a free version quit pestering
the nice developers. :)

In the ZFS keynote at KCA:

it was stated that they''re hoping to get de-dupe and crypto in by the  
end of the year.

At LISA09 in Baltimore next week, Darren is scheduled to give an update
on the ZFS crypto project.  We should grab him, take him to our secret
rendition site at Inner Harbor, force him into a comfy chair, and beer- 
board
him until he confesses.

...ssshhhh, don''t tell Darren ;-)

I can supply the horribly fluffy pillows and the {whiskey, vodka, gin, rum, ...}
if the comfy chair isn''t enough to make him talk.

In all seriousness, if any of the ZFS folks see me at the bar at LISA, hit me up
for a drink or 3 - I owe ya''

Hey, buy them a beer from me, too! (Easy for me to say, as I cant shell out
money). ZFS developers rocks. Hard. And long.
