    摘要: A storage management device receives a request to restore a portion of a data store to its content at a specified past time, which is selected from a substantially continuous time interval. In response to the received request, the storage management device stores in the portion of the data store content that was stored in the portion of the data store at the specified past time and that was overwritten since the specified past time.

    摘要: A method, apparatus, and system for accessing units of storage that depends at least in part on an address of the unit of storage and the time that data was written to the unit of storage. By accessing units of storage in response to a time, prior images of a data store can be generated substantially instantaneously.

    摘要: A storage management device records write requests that are directed to a data store. In one embodiment, the storage management device records a plurality of write request entries, each one of which includes information relating to a write request, in at least one first database table, and maintains, for each first database table, at least one record in a second database table. The one or more records in the second database table include data representing the effects of the write requests on a state of at least one portion of the data store. In one such embodiment, each time that one write request entry is recorded in one first database table, the storage management device updates at least one record in the second database table.
