It's a bit like a hard update, but it won't hurt your disks as much
if your system crashes... ;-P

On a more serious note, it's a technique for ensuring the integrity of
disks after a system crash or power failure.  Like journalling, they 
don't guarantee data won't be lost, but instead that the disks will be 
in a consistent state at recovery.

There are many many papers on the subject on the web, if you're 
interested.
