Hmm opendedup requires java which I'm not allowed to use.

[CentOS] Dedup (again)

2011-09-15 Thread Fajar Priyanto
Hi all,
Back in March someone asked about deduplication in Centos and I
replied I'm using LessFS.
I want to report that my overall experience is that I have performance
issue up to the point that I would like to abandon it.

The OP was asking http://www.opendedup.org/
How is it?

Thanks
Fajar

dedup is an extremely new feature in ZFS and not even enabled in the 
latest release of supported Solaris 10...  so, I'd wonder if the A) the 
source code for it is in the open source version (Oracle hasn't been 
releasing new source code to much of anything) or B) its considered 
stable yet.

frankly, the only place I'd consider using any sort of dedup is in a 
backup system like backuppc, where its implemented at an application 
level rather than transparently in the file system.  as your file system 
object count grows, it becomes astronomically more expensive.
