I had 2 ScadaPack 357 RTUs today recover from a power failure and come up with a corrupt database/bad CRC error. Can anyone provide feedback on why this might happen, and provide strategies to mitigate?

Both RTUs are on UPS, and the line side is monitored so the RTU is aware of the power state. If it's possible to programmatically initiate a graceful shutdown to protect the application I'm interested in exploring those options. The coin battery voltage is monitored and is still 3700mV, so the battery backed RAM should have survived intact.
