What's the best automated way to setup a disaster recovery environment in our
situation?

We have a production sql 2000 database receiving orders. If the machine
crashes, we would like to use another server box to function ASAP (about 0.5
to 1 hr latency is tolerable). Shall we setup a replication? What kind of

Pls have a look at the MS articles on High Availability. Your options
include replication, log-shipping and clustering. Database Mirroring is an
extra option if you decide to move to SQL Server 2005.

Replication is a solution for disaster recovery. The caveats with using it
are no automated failover, and failback can be difficult. With
bi-directional transactional replication failback is much easier.

You might want to look into a third-party tool such as LifeKeeper from
SteelEye Technology. You could replicate to a second server with
automatic failover within about 1-2 minutes. You could also choose a
third target across a WAN for true disaster recovery and data
protection in the event of a complete site lose.
