Abstract
A method for data protection includes accepting data for storage from one or more data sources (24). The data is sent for storage in a primary storage device (28) and in a secondary storage device (32). While awaiting an indication of successful storage of the data in the secondary storage device, a record associated with the data is temporarily stored in a disaster-proof storage unit (48) adjacent to the primary storage device. When an event damaging at least some of the data in the primary storage device occurs, the data is reconstructed using the record stored in the disaster-proof storage unit and at least part of the data stored in the secondary storage device.

42. A method for data protection, comprising:
-
predefining a time period of interest that occurs immediately preceding or during disaster events; accepting from one or more data sources data that is sent for storage in a storage device; temporarily storing records associated with the data in a disaster-proof storage unit such that, when an event damaging at least some of the data in the storage device occurs, the disaster-proof storage unit holds only the records associated with the data that was accepted during the predefined time period relative to the event; and in response to the event, extracting the records from the disaster-proof storage unit and acting upon the extracted records. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50)

51. Apparatus for data protection, comprising:
-
a disaster-proof storage unit; and a protection processor, which is configured to hold a definition of a time period of interest that occurs immediately preceding or during disaster events, to accept from one or more data sources data that is sent for storage in a storage device, and to temporarily store records associated with the data in the disaster-proof storage unit such that, when an event damaging at least some of the data in the storage device occurs, the disaster-proof storage unit holds only the records associated with the data that was accepted during the predefined time period relative to the event. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59)
