How can I mirror a directory structure with all repositories and branches?

[Nicholas Allen]

Thanks - I considered this but rsync won't lock when users are 
committing to a branch. So it could mirror the directory in a half 
committed state. Is that what you meant by possible brokenness? The 
mirror needs to act as a reliable backup system and so brokenness if 
definitely not something we would want...

Cheers,

Nick
