24x7 on an Intel platform running NT with <splutter> Powerbuilder front-ends!!

Have you considered getting Microsoft Prayer? It's a little daemon that runs in the background praying to the deity of your choice that nothing will crash. :-)

Seriously though, you will have to look at configuring the 2nd Compaq as a hot standby, and then test it -thoroughly-. As for backups, don't rely solely on DATs (I assume your using the DAT drives on the Compaqs for backups?). We have had DATs failing on us several times. So either make another DAT copy of every backup, or some other backup media in addition.
