Preventing data corruption in the event of an extended power outage

PC and server operating systems are designed to do "graceful" shutdowns, performing processes such as saving memory, stopping applications and services, etc.

 

However, an abrupt loss of power causes hard shutdowns, resulting in lost or corrupted data and a lengthier time-to-recovery after power returns.

 

During an extended power outage, defined as any outage that might outlast the Uninterruptible Power Supply's (UPS) runtime, if the system is equipped with UPS shutdown software, it can communicate with the UPS and perform a graceful, unattended system shutdown before the UPS battery is exhausted.
