Server-based backup system for user data

1. A computer-implemented method performed by a host system having one or more processors, the method comprising:

sending, by the one or more processors, first information to a client system via a communication network, the first information including content of a structured document and an embedded archiving tool;

automatically receiving, by the one or more processors, one or more inputs from the client system via the communication network, the one or more inputs including user-edited information for the structured document;

in response to automatically receiving the one or more inputs, making one or more changes to a backup copy to second information stored by the host system;

determining, by the one or more processors, an unintended restart condition for the structured document; and

in response to determining the unintended restart condition for the structured document, sending at least a portion of the backup copy to the client system.

2. The method of claim 1 , wherein the unintended restart condition is a crash or accidental closure of the structured document.

3. The method of claim 1 , wherein determining the unintended restart condition includes performing a recovery process, the recovery process including receiving a request from the client system to provide information from the backup copy to the client system.

4. The method of claim 3 , wherein the recovery process further includes verifying a user associated with the backup copy.

5. The method of claim 1 , wherein determining the unintended restart condition for the structured document is based on detecting a restart condition.

6. The method of claim 5 , wherein the restart condition is detected by the host system.

7. The method of claim 6 , wherein the restart condition is detected by the host system based on an existence of one or more archive files stored by the host system.

8. The method of claim 6 , wherein the restart condition is detected by the host system by sending a request to the client system for information corresponding to a particular identifier associated with the structured document.

9. The method of claim 1 , wherein the structured document is a web page.

10. The method of claim 9 , wherein the embedded archiving tool is embedded in web page instructions of the first information.

11. The method of claim 9 , wherein the embedded archiving tool is configured to archive content provided by a user to an application program via the web page.

12. The method of claim 11 , wherein the application program is selected from the group consisting of an email application, a text processor, a spread sheet application, a presentation authoring tool, a blog authoring tool, a web page-based form for entering information to be stored in a server, a web-page authoring tool, and an advertising program registration tool.

13. The method of claim 9 , wherein sending at least the portion of the backup copy to the client system includes inserting restructured content into one or more fields of the structured document.

14. The method of claim 1 , wherein the embedded archiving tool is configured to archive content provided by a user when an archiving condition is satisfied.

15. The method of claim 14 , wherein the archiving condition is at least one of: when at least a pre-determined number of modifications to content have occurred, when a length of the content increases by at least a pre-defined amount, when an application program is closed, or when a web browser is closed.

16. A host system comprising:

memory configured to store first information, the first information including content of a structured document and an embedded archiving tool; and

one or more processors operatively coupled to the memory, the one or more processors being configured to:

send the first information to a client system via a communication network;

automatically receive one or more inputs from the client system via the communication network, the one or more inputs including user-edited information for the structured document;

in response to automatically receiving the one or more inputs, make one or more changes to a backup copy to second information stored by the host system;

determine an unintended restart condition for the structured document; and

in response to determining the unintended restart condition for the structured document, send at least a portion of the backup copy to the client system.

17. The host system of claim 16 , wherein determination of the unintended restart condition includes performing a recovery process, the recovery process including receiving a request from the client system to provide information from the backup copy to the client system.

18. The host system of claim 16 , wherein determination of the unintended restart condition for the structured document is based on detecting a restart condition.

19. A non-transitory computer-readable storage medium having instructions stored thereon, the instructions, when executed by one or more processors, causing the one or more processors to perform a method comprising:

sending first information to a client system via a communication network, the first information including content of a structured document and an embedded archiving tool;

automatically receiving one or more inputs from the client system via the communication network, the one or more inputs including user-edited information for the structured document;

in response to automatically receiving the one or more inputs, making one or more changes to a backup copy to second information stored by the host system;

determining an unintended restart condition for the structured document; and

in response to determining the unintended restart condition for the structured document, sending at least a portion of the backup copy to the client system.

20. The non-transitory computer-readable storage medium of claim 19 , wherein determining the unintended restart condition either:

includes performing a recovery process including receiving a request from the client system to provide information from the backup copy to the client system; or

is based on detecting a restart condition.
