Abstract

Technology is disclosed for context sensitive synchronization of a distributed cloud-based file system across multiple devices and for providing seamless merging of conflicting data objects. In some embodiments, data objects of a user are stored across multiple computing devices associated with a user, e.g., mobile computing devices such as a tablet, a laptop, or a smartphone, and/or at server systems, e.g., cloud-based storage servers, in a distributed cloud-based storage system. The described technology intelligently synchronizes the data objects based on context and manages potential conflicts.

detecting a conflict between data object information associated with the first computing device and data object information associated with a second computing device;

determining a losing computing device of the first computing device and the second computing device; and

determining a modification to the data object information associated with the losing device that resolves the conflict.

5. The computer-implemented method of claim 4, further comprising:

waiting for the first computing device to cease accessing the data object information associated with the losing device;

resolving the conflict by sending the instruction to the losing device requesting that the losing device perform the modification to the data object information.
