Crash recovery of a computing system in the context in which the computing system includes a volatile memory which has contents lost due to the crash, an intermediate non-volatile memory that (together with the volatile memory) contributes to the active memory of the computing system, and non-volatile storage. The recovery occurs by identifying pages that were in the volatile memory at the time of the crash. For each of these pages, the recovery determines whether to recover the page into the volatile memory from either the intermediate non-volatile memory or the storage, and then performs the recovery. In embodiments in which access speeds for the intermediate non-volatile memory may be much faster than for the storage, and in which much of the pages to be recovered are recovered from the intermediate non-volatile memory, the recovery time may be reduced. |
