Apparently, my UPS computes for it by considering the power drained per unit time. I should be quick to say that my UPS can only send two signals: power failure and low battery. It seems that the reliability and functionality of my UPS is good for 2 computers at most only. It does give 20 minutes backup time for my single desktop, but the monitor has to be off. I'm not recommending my UPS, though. > There are a number of things you have to consider here. First of course is > metadata and filesystem structure integrity.

Data loss is not really a problem for me as long as there is no harm done to the system. I install and configure software with backup power, so I only plan to do work (eg: word processing) without backup power. Will it be fine to do so? I've never used a full journaling file system before. _ Philippine Linux Users Group.
