Abstract: Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.

Abstract: Embodiments of the present disclosure include systems and methods to facilitate top down delete or un-synchronization on delete of a synchronization client to a cloud-based platform. The disclosed technology innovates the mechanism the synchronization client processes local deletes so that instead of synchronizing the delete of each individual item across to the cloud-based platform, it can accumulate the individual item deletes into a top-level folder delete and that top-level folder delete can be what is communicated across to the cloud-based platform. Embodiments of the present disclosure also include systems and methods for depicting item synchronization between a local and cloud based platform/service (e.g. the Box service). In some embodiments the system can identify items that cannot be synchronized between the local and cloud based platform/service (e.g., cloud based collaboration or storage platform/service).

Abstract: Embodiments of the present disclosure include systems and methods of conflict resolution, retry condition management and/or handling of problem files in the synchronization architecture of the cloud-based platform. One embodiment of the disclosed technology detects conflicts between incompatible changes made on opposite file systems based on file system sync results when executing a sync event on the file system. In one embodiment, the disclosed technology applies self-healing strategies when unexpected failures occur. For example, if a synchronization action fails repeatedly, an external action (e.g., from user, file system, etc.) can return the system back to a consistent state again.
