Abstract
A backup power system includes continuously powered memory (CPM) backup functionality integrated with uninterruptible power supply (UPS) backup functionality, for use with a computer system. Battery energy level is monitored to detect when a threshold energy level is reached. The threshold level is an energy level required to ensure a successful CPM backup operation. When a utility power interruption is detected, if the battery energy level is above the threshold, UPS operation is provided. When battery energy level reaches the threshold, CPM operation is provided.
