Linux Deduplication

I have been looking for an Open Source data deduplication system that is stable enough to use for SMB file servers and for VMware iSCSI targets. Just recently I found a couple that show major promise. I wouldn't say that I am an expert on the subject and to be honest I really am a bit scared of the technology in general because the information stored it not "all there" if you know what I mean.

I think it is wise to really justify the need for it and at most always have some kind of backup to make sure you can get to the un-duped data just incase.

Here are some good open source projects that you might want to take a look at and test with:

Keep in mind that you need to research how to implement this technology. I will eventually write an entire post on how to set up some sort of test bed for each. I will include a step by step scenario using it for SMB sharing.
