rsync - Aug 2010 - HDB, a hard drive backup program

Hey all, I'm writing a tool:

http://www.subspacefield.org/security/hdb/

It is very similar in some ways to rsync, except it's meant for backing up
locally to removable HDDs, and it keeps metadata around when the HDD is
removed.

I figured I'd ping people here to see if they are interested in
participating in the brainstorming sessions.  I figure you know a lot
more than me about this kind of stuff.

This is an interesting approach. I look forward to seeing the project develop.

Thanks for the link.

Maybe I'm misinterpreting "keeps metadata around when the HDD is 
removed".  Isn't that part of most backup software?

If you haven't already, the Hierarchical Storage Management (HSM) page 
on Wikipedia[1] has a list of software that (probably) does this.  In 
particular, at a former job of mine, we used Tivoli for backups.  It did 
what you're stating (kept metadata about backups around even without the 
backups).
