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.
Claims29
A method for data protection, comprising:
- in a system that comprises only a single storage device, accepting from one or more data sources data that is sent for storage only in the single storage device;
- storing the accepted data in the single storage device at a site;
- temporarily storing records associated with the accepted data in a disaster-proof storage unit at or adjacent to the site, including deleting one or more previous records from the disaster-proof storage unit so as to free memory space in the disaster-proof storage unit for storing the records, such that when an event damaging at least some of the data in the single storage device occurs, the disaster-proof storage unit only holds the records associated with the data that was accepted during a limited period preceding occurrence of the event;
- and
- in response to the event, extracting the records from the disaster-proof storage unit and acting upon the extracted records.
Apparatus for data protection, comprising:
- a disaster-proof storage unit, enclosed in a reinforced disaster-proof enclosure;
- and
- a protection processor, which is configured to accept from one or more data sources data that is sent for storage only in a single storage device, and to temporarily store records associated with the data in the disaster-proof storage unit at or adjacent to a site of the single storage device, including deleting one or more previous records from the disaster-proof storage unit so as to free memory space in the disaster-proof storage unit for storing the records, such that when an event damaging at least some of the data in the single storage disk occurs, the disaster-proof storage unit holds only the records associated with the data that was accepted during a limited period preceding occurrence of the event.
A method for data protection, comprising:
- accepting from one or more data sources data that is sent for storage only in a single storage device;
- storing the accepted data in the single storage device at the site;
- temporarily storing records associated with the accepted data in a disaster-proof storage unit, enclosed in a reinforced disaster-proof enclosure which does not encompass the single storage device, at or adjacent to the site, including deleting one or more previous records from the disaster-proof storage unit so as to free memory space in the disaster-proof storage unit for storing the records, such that when an event damaging at least some of the data in the single storage device occurs, the disaster-proof storage unit holds the only records associated with the data that was accepted during a limited period preceding occurrence of the event;
- and
- in response to the event, extracting the records from the disaster-proof storage unit and acting upon the extracted records.
