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 for recovering data, comprising:

an antenna; and

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

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

3. The recovery unit according to claim 2, wherein the indication is provided to the storage unit via the primary storage device.

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

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

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

7. The recovery unit according to claim 5, wherein the first transceiver is configured to only communicate with the second transceiver in response to the second transceiver transmitting the unique identity to the first transceiver.

8. The recovery unit according to claim 1, wherein the first wireless transceiver is configured to operate in a wireless network, the recovery unit further comprising a satellite terminal which is configured to communicate with the wireless network via a satellite network.

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

10. The recovery unit according to claim 8, wherein the recovery unit comprises an operating console which in an on-line mode of operation of the recovery unit is configured to relay the records from the first wireless transceiver to the satellite terminal.

11. The recovery unit according to claim 10, wherein the operating console comprises a memory, and wherein the operating console in an off-line mode of operation of the recovery unit is configured to store the records in the memory and not relay the records to the satellite terminal.

12. The recovery unit according to claim 11, 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.

13. The recovery unit according to claim 11, wherein in the off-line mode of operation the first wireless transceiver is configured to communicate with the second wireless transceiver only after receipt of authentication from the wireless network.

14. The recovery unit according to claim 1, and comprising a recovery processor which is configured to receive the records and in response recover the data and store the recovered data in a non-volatile storage medium.

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

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

17. The recovery unit according to claim 1, wherein the second wireless transceiver is configured to communicate only with the first wireless transceiver.

18. The recovery unit according to claim 1, wherein the first wireless transceiver is configured to communicate concurrently with multiple second wireless transceiver of multiple respective storage units.

19. A method for recovering data, comprising:

holding records associated with the data in a storage unit comprising a first wireless transceiver;

when an event damaging at least some of the data occurs, bringing a data record recovery unit comprising a second wireless transceiver into proximity with the storage unit; and

configuring the second wireless transceiver to communicate only with the first wireless transceiver so as to receive the records from the storage unit for the recovery of the data.

20. Apparatus for recovery of data, comprising:

a storage unit, comprising a first wireless transceiver, which is configured to store records associated with the data; and

a data record recovery unit, comprising a second wireless transceiver, which is configured, when an event damaging at least some of the data occurs, to be brought into proximity with the storage unit, and, when in proximity thereto, to communicate via the second wireless transceiver only with the first wireless transceiver so as to retrieve the records from the storage unit for the recovery of the data.

21. A method for recovery of data, comprising:

storing records associated with the data in a storage unit comprising a first wireless transceiver;

when an event damaging at least some of the data occurs, bringing a data record recovery unit comprising a second wireless transceiver into proximity with the storage unit; and

configuring the second wireless transceiver to communicate only with the first wireless transceiver so as to retrieve the records from the storage unit for the recovery of the data.

22. A recovery unit for recovering data, comprising:

an antenna; and

a first wireless transceiver, which is configured to communicate via the antenna only with a second wireless transceiver of a storage unit that holds records associated with the data, and, when an event damaging at least some of the data is simulated and the recovery unit is brought into proximity with the storage unit, to receive the records from the storage unit for recovery of the data.

23. A method for recovering data, comprising:

holding records associated with the data in a storage unit comprising a first wireless transceiver;

when an event damaging at least some of the data is simulated, bringing a data record recovery unit comprising a second wireless transceiver into proximity with the storage unit; and

configuring the second wireless transceiver to communicate only with the first wireless transceiver so as to receive the records from the storage unit for the recovery of the data.
