TFS2005: Mirroring single server installation, best practice

Hi.
I have one single server Microsoft TFS solution running (single tier). I
have been asked to enhance the security and up time. My plan is to install
TFS on another server and mirror the SQL-server databases. But as far as I
can figure out this way is mainly used when running dual tier.
Have anybody experience that might be usefull for me regarding mirroring of
single tier solutions?

Best regards, Brian
