OpenSolaris Dedupe for home use
Posted by Sam
I know that dedupe will save a ton of space at work. We have lots of Subversion repos checked out on servers and lots of similar files like swfaddress and jquery that are reused in a lot of our projects. But I've been curious how useful it would be with my personal files. Here's what I've found when I deduped files from my home directory.
- Photos: 5.5GB savings (34GB pre-dedupe/28.5 post-dedupe)
- Music: No savings
- Projects: 1GB savings (2.2GB pre-dedupe/1.22 post-dedupe)
As you can see there are some decent space savings to be had even for home/power users. The savings would be even greater if I had enabled compression as well but I was more curious about dedupe since compression is fairly common these days.

Hi Sam, Interesting that music didn't dedup at all....especially since most new music sounds so much alike!
