If you have a server or any computer that is important, it needs an UPS. Something large enough for 5-10 minutes of power outage. But it is not enough to just plug the power into the UPS. You must also plug into UPS data port. And set up the software that will allow the computer to detect the power outage and shutdown before the battery runs out.
This is non-negotiable.
Not doing this risks you showing up Monday morning and not getting any work down while an admin drives 100 km to fix a problem.
And if you have any piece of important electronic equipment, you'll want a filter. And no the fuse on your power bar doesn't count.
