Abstract

A method of storing data from a network address in a database of a portable electronic device. The method includes obtaining at the portable electronic device, a data record from the network address, storing the data record along with a network address identifier, and transmitting the network address identifier to a backup device for retrieval and storage of the data record from the network.

Claims

1. A method of storing data from a network address, in a database of a portable electronic device, the method comprising:

obtaining at said portable electronic device, a data record from said network address;

storing said data record along with a network address identifier; and

transmitting said network address identifier and a content representation for said data record to a backup device for retrieval and storage of said data record from said network.

2. The method according to claim 1, wherein storing said data record comprises storing said content representation for said data record.

3. The method according to claim 1, wherein said network address identifier is stored as a field of said data record.

4. The method according to claim 2, wherein said network address identifier and said content representation are stored as fields of said data record.

5. The method according to claim 1, comprising:

receiving at said backup device, said network address identifier and said content representation from said portable electronic device;

said backup device retrieving said data record from a network using said network address identifier;

storing the data record in a backup database.

6. The method according to claim 5, comprising:

comparing said content representation for said data record to a representation of content of said data record retrieved by said backup device, prior to storing said data record; and

if said content representation is in agreement with said representation of said content of said data record retrieved by said backup device,

proceeding to said storing the data record in the backup database,

if said content representation is not in agreement with said representation of said content of said data record retrieved by said backup device;

transmitting a request for full data record transfer from said portable electronic device;

receiving said full data record from said portable electronic device; and

proceeding to said storing the data record in the backup database.

14. A computer-readable medium having computer-readable code embodied therein for execution by an electronic device for implementing the method of claim 1.

7. A method of storing data from a network address at a backup device, the method comprising:

receiving at said backup device, a network address identifier associated with a data record stored at a database of a portable electronic device, and a content representation for said data record;

retrieving said data record from said network using said network address identifier; and

comparing said content representation for said data record to a representation of content of said data record retrieved by said backup device, and

if said content representation is in agreement with said representation of said content of said data record retrieved by said backup device, storing the data record in said backup database.

8. The method according to claim 7, wherein if said content representation is not in agreement with said representation of said content of said data record retrieved by said backup device, said method comprises:

transmitting a request for full data record transfer from said portable electronic device; and

receiving said full data record from said portable electronic device; and

storing the data record in said backup database.

9. The method according to claim 8, comprising generating said representation of content of said data record at said backup device, prior to said comparing.

10. The method according to claim 8, comprising generating a local hash value representative of said data record retrieved by said backup device, prior to comparing.

11. The method according to claim 10, wherein receiving said content representation for said data record comprises receiving a hash value representative of said data record from said portable electronic device.

15. A computer-readable medium having computer-readable code embodied therein for execution by a processor for implementing the method of claim 7.

12. A system for storing data from a network address, the system comprising:

a memory for storage of a backup database;

a receiver for receiving a network address identifier associated with a data record stored at a database of a portable electronic device and for receiving a content representation for said data record at said portable electronic device; and

a processor operably coupled to said receiver and said memory for retrieving said data record from said network using said network address identifier in response to receipt of said network address identifier, comparing said content representation for said data record to a representation of content of said data record retrieved by said backup device and, for storing the data record retrieved from said network in said backup database of said memory if said content representation is in agreement with said representation of said content of said data record retrieved.

13. A portable electronic device comprising:

a memory for storage of a database of records;

a transmitter and receiver for receiving a data record from a network;

a processor coupled to said memory and said transmitter and receiver for obtaining said data record from said network, storing said data record in association with a network address identifier associated with the data record and a content representation for said data record, in said database of said memory and via said transmitter, transmitting the network address identifier and the content representation for said data record to a backup device during synchronization.
