Abstract: Examples herein disclose an identification of a backup power structure, among various backup power structures, implemented in a storage system. In response to the identification of the backup power structure, the examples select a data loss prevention technique to implement in storing write data to the storage system. The data loss prevention technique is selected among various loss prevention techniques corresponding to the various backup power structures.

Abstract: In some examples, a storage system dynamically selects, in response to a determined type of power backup arrangement used in the storage system, from among different powerloss data protection techniques corresponding to different types of power backup arrangements, The different powerloss data protection techniques each is responsive to loss of power by saving write data according to a common format. In response to loss of power in the storage system, the selected powerloss data protection technique is used to store write data corresponding to write operations in the storage system according to the common format to a recovery storage medium. The storage system recovers from the loss of power in the storage system by using the write data according to the common format stored using the selected powerloss data protection technique.
