Abstract
A system and method for managing a storage system may include recording, in a cache memory, data related to user writes to the storage system; setting a time in a next consistency point (NCP) object with a value greater than the current time; and maintaining a first counter related to the number of user writes recorded in the cache memory and that occurred before the time included in the NCP object and after a time included in a consistency point (CP) object; maintaining a second counter related to the number of user writes that were stored in a persistent storage system and that occurred before the time in the NCP object and after a time in the CP object. A system and method for managing a storage system may include initializing the storage system to a consistent state based on the time included in the CP object.
