server replication?

[Gregor Mosheh]

My employer is looking for solutions to achieve
zero-downtime in the event of a hardware failure. I've
been doing sysadmin for some time, but this is out of
my league, and I wanted to ask the list for any
advice, hints, etc.

For starters, how does such a solution work
conceptually? The possibility of load-balancing
appliances has been suggested; how does this work with
user databases and uploaded files? Our services are
primarily web-based and do involve a significant
amount of users uploading files, and database
(postgres) work.
