We recommend battery backups for a couple of reasons.
1) Because they even out the fluctuation in power coming into your computer. They make your computer last longer because of this.
2) Because if you site loses power, then your computer crashes. Doing that could be a non issue or it could be a serious issue. It just depends on what your computer was doing at the time it crashed.
