What does everyone else do? Lose emails?
No. We have decent power backup systems and management interfaces so systems don't abruptly lose power. We also use good hardware with a good mainline kernel driver track record.
I think you forgot about the two failure scenarios that you need to worry about in this thread:
- Kernel/system crash
- Power loss
If you're using decent hardware with decent drivers that have been fleshed out over the years in mainline, you can forget #1. If you have decent UPS units, management interfaces, and shutdown software, you don't need to worry about #2.
After those two are covered, the only thing you need to worry about is hardware going flaky. In that case, nothing will save you but good backups. Thankfully most hardware today is pretty reliable (system boards, HBAs, etc).
