Nothing.
What you NEED is good surge protection. The battery backup
"feature" of a UPS is gravy.
The first 400 gigs of music I lost due to power failure taught me otherwise.
You DID NOT lose data because of a power drop.
IF the drive was hozed, it was because a surge (spike) blew thru the
power supply and hit the drive.
UPS = Surge protector + Battery backup.
The surge protector protects your equipment by stopping spikes and
evening out / cleaning up the power flow. The battery backup does
nothing but keep your equipment running during the power outage.
Brakes vs Spare Gas Tank. You crashed because your brakes failed.
All the spare gas tank did was keep the engine running while you were
waiting for the tow truck to flip your car back over.
Most people are too cheap to buy good surge protectors (I definitely
fit into that category!). That's where the marketing for the UPS
comes in -- you end up buying the better surge protector because it's
part of the UPS box.
And, of course, all bets are off if everything isn't properly grounded....
