Abstract:
Methods and systems for accessing data from a previous point in time, including receiving data stored in a storage system of addressable memory, the storage system including a plurality of addresses, receiving a journal history of write transactions for the storage, each write transaction including (i) a plurality of designated memory addresses, (ii) a corresponding plurality of current data to write in the designated memory addresses for storage, and (iii) a time indicator, generating a data structure that represents a virtual interface to the storage at a specified point in time, based on the write transactions in the journal history having a time subsequent to the specified point in time, and enabling a user to process the data from the specified point in time, via the virtual interface and the journal history.
