Battery backup control method and apparatus, server, and non-volatile readable storage medium

This application discloses a battery backup control method and apparatus, a server, and a non-volatile readable storage medium, and relates to the field of battery power supply. The method includes: acquiring a current backup state of a battery in a case of detecting that a power supply unit is in non-redundant power supply, where backup states include a cold backup state and a hot backup state; maintaining the hot backup state when the current backup state is the hot backup state; sending a discharge enable signal to the battery when the current backup state is the cold backup state; and controlling the current backup state of the battery to update to the hot backup state from the cold backup state according to the discharge enable signal. In the method, the battery is controlled to be in the hot backup power supply in the case of detecting that the power supply unit is in the non-redundant power supply, and since the hot backup power supply provides a discharge capability to the outside, after the power supply unit is disconnected, the battery may serve as a supply unit for data backup, thereby improving power supply stability and reliability of a storage system, and reducing the risk of data loss.
