lazy mirror / live backup

[Ollivier Robert]

According to Mike Wolman:
> I'd like the ability to have gmirror do a more efficient re-silvering (or 
> re-syncing) of the mirror members when a planned disconnect occurs. This 
> would significantly reduce the mirror rebuild time for any component which

> also reduce network usage and could be used for remote asynced mirrors 
> thus providing a live backup for laptops/workstations.

Do you see that you are describing ZFS there?  Considering the status of
ZFS right now, I think it is not worth really trying to implement such
scheme in gmirror.
