Getting a database on one server to match another

Sorry wasn't too clear was I.
The second server is our disaster recovery server, so we
want our second server database to be as up to date as
possible with the production database.

Hari already answered this with:
1) Log Shipping
2) Transactional replication
If the disaster recovery server does not need to be operational, then log
shipping would be good.You may also want to consider Double-Take from NSI
Software. This replicates the SQL Server data files at the block level on
disk and ensures transactional consistency.

I'll have a look at transactional replication as we backup
the Production db by log files and to be honest I'm not
too sure on what will happen if we change it so it updates
asap.
Thanks for your time

nd to use replication for fail

I really don't think transactional replication is a good high availability
solution. There are many drawbacks to using this. Do a search on the web for
high availability sql server and you should find some good information.
Kimberley Tripp did a great presentation on high availability, perhaps
search for that.
Log shipping might be a good way to go, you can have a latency of 5 minutes
with this solution.
