While I'm quite willing to concede that a crashed machine can cause
corruption in a compressed file system you wouldn't otherwise see, I'm
also willing to admit there are times, much like the OP was talking
about, where that's an acceptable loss, like Data Warehousing.
No way would I run a db for data that mattered on a compressed file system.
