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

If your branches are on an LVM-enabled system and stored on a logical volume, 
you can create a snapshot, run 'rsync -avz' on that, and you're good to go. 
All you need to make sure of is that bzr isn't running on any of the 
repoitories at the time that the snapshot is created.

The other solution would be to use a shell script to iterate through the 
branches, doing a 'bzr push' one at a time on them to another location.  Or, 
starting several 'bzr push' instances in the background at the same time, if 
you must have point-in-time consistency amongst all the branches.
