Experts,
I have a SQL 2005 database server which has about 20 user databases which  total upto 1 TB.We have nightly backups and they go onto the tape eventually everyday.
In case this server crashes what are my options beside restoring from the backups.
someone mentioned Warm Standby Server, is it a feasible solution? pros and cons? basically we want to reduce the down time.

please suggest
regards

You could go for high availability concept of SQL Server like Mirroring, Replication, clustering, log shipping etc.

you can maintain warm stand by server with Log Shipping, which is not a bad idea. have a look at below URL

log shipping is the way to go here, database mirroring would also work if you have the correct server version.

Thanks for the updates.

I have a sql server 2005 database server, machine A(primary dbserver), with 20 databases on it. I have hardware available for another SQL Server 2005. What do i do from here?  
1) intall SQL Server 2005 on machine B (which would be standby server)
 and then what are the steps to do..? i am guessing
2) backup the 20 databases  from Server A
3) restore them on Server B

4) how do i transport the transaction log from server A to B?
Can this be automated, if so how? can i set it to happen every hour?
 or what  is the optimal way of doing it?

regards...

i guess so. Thanks for the updates. i just created a second instance on sql server 2005 and having issue connection. i verified that the "allow remote connections" is checked . i believe something is wrong with the TCP/IP port. i played with SQL Configuration Manager and messed it up. how do i fix it? the first instance is working fine and it is listening on port 1433. The error log for the named isntance is showing , port 3000 and 3831, what do i have to do?

it will require specialized hardware, and maintenance....you're probably talking several hundred thousand to do it correctly and robustly.

Yep...the licenses aren't whats going to cost you the most in active/passive...its the hardware that you have to pay for that will basically be sitting idle when you're on one node.  Its not a cheap solution...a good one, YES...a cheap one to do right, no.
