I wasn’t sure what the subject should really be so I just used some keywords. I’ve not the following before so I thought I’d ask for some terse steps which I can research. Point me in the right direction and I’ll find my way :)
I want to copy some dbs to a backup server. If server 1 fails—power supply dies for example—server 2 will immediately take over. What are considered the best practices to sync db files in real-time from server 1 to server 2? Thankyou.

If you need realtime, you're almost for sure going to have to look at a clustering solution.  You could also use logfile backups or transactional replication, but you do run into the problem of a possible lag time and lost transactions.

Here is a start:

Here are some additional articles specific to SQL Server:

I would highly recommend clustering with Windows 2003 (if you decide to cluster).  The clustering support in 2003 is awesome...

(Unfortunately) I don’t have SQL Server Enterprise, which I’ve discovered is required to implement a real-time backup plan. Guess I’ll have to resort to quite frequent backups to Server 2. I intend to backup the complete files and not incrementally—the databases are 2-5 gigs. Does it seem sensible, or this a better way of going about it, to restore the complete files to SQL Server on Server 2 if Server 1 fails?

NO, Enterprise is NOT required......You have several other options--Log Shipping, or transactional replication.  Personally, I would recommend logshipping--this is my favorite link to setting it up:
