well, some experience, here a few "lessons":
- costs explode as you try to achive "real time fail over".
- its all about planning. You can get away with an unplanned
datacenter to some point. But replicating such a "non-plan" will not
work.
- Its relatively easy to replicate a database in close to real time.
But the place I am running into difficulties is file systems.
'rsync'/'unison' are ok if you can afford to lose a few minutes of
data. There are network file systems, but I haven't used any (realize, I
am not talking about 'NFS' or 'AFS', but about real
distributed/redundant file systems like GFS)

In short, it comes down to money. There are also a few services that
may be more cost efficient (I think Sunguard does this).

And don't forget, there is a SANS Step-by-Step Guide ;-)
