I'm pretty sure all 5 years fit on one cd-rom -- I've been using 4 years as an eternity dds dataset, along with some other stuff, and I think it is less than 500mb, although one of the problems with my current eternity file system under linux is that there is no way of telling how big a directory is (yay VFS kludges).
Sounds like you are building a file system interface to a distributed data store, cool. Want to give us a brief description of what it does? I know I'd be interested, I'm sure others would too.

I've mostly just used postgres, a db, for doing database stuff, and kludged together a disgusting collection of kernel patches and usermode processes to make data appear as a directory structure in a modified version of the ext2fs (actually, most if it is in the VFS level as it should be, but I didn't know enough about it when I started to cleanly separate the two. Oh well). It's not distributed, it's not reliable, it's not secure. It's just me learning how to play with virtual file systems. And unfortunately most of the code is stolen from commercial/proprietary software, so I can't really release it. My current Eternity DDS plan is to have a linux file system and an http interface to the data store up in the first incarnation. I'm at the stage of playing with technology for the interface layer, and having a vaguely workable plan for inter-server communication. Once I have something which can be demonstrated, I'll post an announcement to the technical people who would be interested. I've entered the Eternity DDS idea into a MIT-sponsored new business competition, etc. My current Eternity homepage is at http://sof.mit.edu/eternity/, although it's rather sparse. -- Ryan Lackey rdl@mit.edu http://mit.edu/rdl/
