Abstract

A recovery unit for recovering data includes an antenna and a first wireless transceiver. The first wireless transceiver is configured to communicate via the antenna only with a second wireless transceiver of a storage unit that holds records associated with the data. When an event damaging at least some of the data occurs and the recovery unit is brought into proximity with the storage unit, the recovery unit receives the records from the storage unit for recovery of the data.

Claims

1. A recovery unit, comprising:

a transceiver, which is configured to communicate in accordance with a same wireless protocol that is also designated for normal wireless communication between a secure storage unit and a wireless network; and

a processor, which is configured, when the normal wireless communication between the secure storage unit and the wireless network is unavailable due to a disaster event and the recovery unit is brought into proximity with the secure storage unit, to control the transceiver to communicate with the secure storage unit directly, using the same wireless protocol used for the normal wireless communication but regardless of authentication of the secure storage unit by the wireless network, to recover data from the secure storage unit, and to locally store the recovered data in a memory at the recovery unit.

2. The recovery unit according to claim 1, wherein a primary storage device stores a first copy of the data, and wherein a second storage device is configured to provide an indication of successful storage of the data after a second copy of the data is stored therein, and wherein the primary storage device provides the indication to the secure storage unit.

3. The recovery unit according to claim 1, wherein the secure storage unit is configured to delete the records after receipt of an indication of successful storage of the data.

4. The recovery unit according to claim 1, wherein the secure storage unit comprises a memory having an identification section providing a unique identity for the secure storage unit.

5. The recovery unit according to claim 4, wherein the identification section comprises a subscriber identity module.

6. The recovery unit according to claim 4, wherein the transceiver is configured to only communicate with the secure storage unit in response to the secure storage unit transmitting the unique identity to the transceiver.

7. The recovery unit according to claim 1, wherein the recovery unit further comprises a satellite terminal which is configured to communicate with the wireless network via a satellite network.

8. The recovery unit according to claim 7, wherein the wireless network comprises one of a cellular network, a WiMax network, and a WiFi network.

9. The recovery unit according to claim 7, wherein, in an on-line mode of operation of the recovery unit, the processor is configured to relay the recovered data from the transceiver to the satellite terminal.

10. The recovery unit according to claim 9, wherein, in an off-line mode of operation of the recovery unit, the processor is configured to store the recovered data in the memory and not relay the recovered data to the satellite terminal.

11. The recovery unit according to claim 10, wherein the recovery unit is configured to initially operate in the on-line mode, and to operate in the off-line mode after determining that operation in the on-line mode is unsuccessful.

12. The recovery unit according to claim 1, wherein the transceiver and the processor are configured to communicate with a recovery processor which is configured to receive and store the recovered data in a non-volatile storage medium.

13. The recovery unit according to claim 1, wherein the transceiver comprises one of a femtocell base station and a picocell base station.

14. The recovery unit according to claim 1, wherein the transceiver comprises cellular test equipment that is configured to emulate a cellular base station.

15. The recovery unit according to claim 1, wherein the secure storage unit is configured to communicate only with the transceiver.

16. The recovery unit according to claim 1, wherein the transceiver is configured to communicate concurrently with multiple secure storage units.

17. The recovery unit according to claim 1, wherein the processor is configured to authenticate the secure storage unit instead of the authentication of the secure storage unit by the wireless network.

18. The recovery unit according to claim 17, wherein the processor is configured to obtain authentication information from the wireless network while able to communicate with the wireless network, to store the authentication information in the memory, and to subsequently authenticate the secure storage unit using the stored authentication information regardless of ability to communicate with the wireless network.

19. A method for recovering data, comprising:

holding data in a secure storage unit that is configured to conduct normal wireless communication with a wireless network; and

when the normal wireless communication between the secure storage unit and the wireless network is unavailable due to a disaster event, bringing the recovery unit into proximity with the secure storage unit;

communicating between the recovery unit and the disaster-proof storage unit directly, using a same wireless protocol used for the normal wireless communication but regardless of authentication of the secure storage unit by the wireless network, so as to recover data from the secure storage unit; and

locally storing the recovered data in a memory at the recovery unit.

20. A data recovery apparatus, comprising:

a secure storage unit, which is configured to conduct normal wireless communication with a wireless network; and

a recovery unit, which is configured, when the normal wireless communication between the secure storage unit and the wireless network is unavailable due to a disaster event and the recovery unit is brought into proximity with the secure storage unit, to communicate with the secure storage unit directly, using a same wireless protocol used for the normal wireless communication but regardless of authentication of the secure storage unit by the wireless network, to recover data from the secure storage unit, and to locally store the recovered data in a memory at the recovery unit.

21. A recovery unit, comprising:

a transceiver, which is configured to communicate in accordance with a same wireless protocol that is also designated for normal wireless communication between a secure storage unit and a wireless network; and

a processor, which is configured, when the normal wireless communication between the secure storage unit and the wireless network is unavailable due to a simulated disaster event and the recovery unit is brought into proximity with the secure storage unit, to control the transceiver to communicate with the secure storage unit directly, using the same wireless protocol used for the normal wireless communication but regardless of authentication of the secure storage unit by the wireless network, to recover data from the secure storage unit, and to locally store the recovered data in a memory at the recovery unit.

22. A method for recovering data, comprising:

holding data in a secure storage unit that is configured to conduct normal wireless communication with a wireless network; and

when the normal wireless communication between the secure storage unit and the wireless network is unavailable due to a simulated disaster event, bringing the recovery unit into proximity with the secure storage unit;

communicating between the recovery unit and the secure storage unit directly, using a same wireless protocol used for the normal wireless communication but regardless of authentication of the secure storage unit by the wireless network, so as to recover data from the secure storage unit; and

locally storing the recovered data in a memory at the recovery unit.
