A related question:  If you are on a UPS, is it OK to disable ZIL?

The evil tuning guide says "The ZIL is an essential part of ZFS and should never be disabled." However, if you have a UPS, what can go wrong that really requires ZIL?

Opinions?

I've seen enough people suffer from corrupted pools that a UPS is definitely good advice. However, I'm running a (very low usage) ZFS server at home and it's suffered through at least half a dozen power outages without any problems at all.

I do plan to buy a UPS as soon as I can, but it seems to be surviving very well so far.
