And there's actually a *third* possible goal, which is quick recovery
of accidentally deleted (or overwritten, etc.) user data. UFS2
filesystem snapshots are a remarkably easy way to provide this.
And then there's RAID, which doesn't solve any of these problems, but
can help you get back up fast after losing a disk.
Each of these goals has a different "best solution," and in some cases
the solution even depends on the details of the environment. Figure
out exactly what you need before deciding how to fill that need.
