Selective Synchronization in a Hierarchical Folder Structure

摘要

A technique is described to selectively synchronize content on a client database with content from a server database. As the user traverses a hierarchical folder structure of the client database, he may run into content that has been deleted or moved in the server database. If the content is something that the user wishes to store locally, the content can be stored as an orphan. An orphan is content stored on the client that cannot be traversed by the hierarchical folder structure. When the user traverses to a node in the hierarchical folder structure that is missing an object existing on the server, a determination can be made as to whether the orphan object is the missing object. If so, the orphan object can be connected once against to the hierarchical folder structure. This may minimize the content that needs to be re-downloaded from the server.

1. A computer-implemented method, comprising:
receiving, at a processor, a request to synchronize a first folder object in a first folder structure of a first database with a first corresponding folder object in a second folder structure of a second database, wherein the first folder structure is configured to traverse objects stored in the first database and the second folder structure is configured to traverse objects stored in the second database; determining, by the processor, that the first folder object contains a first child object that is missing from the first corresponding folder object; identifying, by the processor, that the first child object is selected for selective synchronization; and converting, by the processor, the first child object to an orphan object, wherein the orphan object is stored in the first database but is inaccessible by traversing the first folder structure.
