Compression Algorithms in Attic

Compression Algorithms in Attic

Hi,
I'm doing an in depth comparison between Attic and ZBackup on compression
ratios and time to archive. I noticed Attic is significantly faster (about
4.4x) than ZBackup. However Attic takes 30% more space than ZBackup on the
same input file set.

I was wondering what compression algorithms does 0.14 and 0.16 use? Also
are there command line options to select different compression algorithms?

Thanks,
Kiran K

Hi,

Could you please share detailed specs or any blog where you are 
publishing it?

Regards.

The evaluation is not complete as we'd like to understand what makes Attic
different in these numbers.
Results are unpublished for now. But they will appear in a later blog post
at http://silverskysoft.com/open-stack-xwrpr/
