Aspects include systems and methods for synchronizing a remote datastore that includes files and data for use by an application on a remote device, which can be represented on the device in a device-specific format, while the remote data store can have a different data representation, such as a relational database or object graph data model. A server can maintain a unique row identifier for each row in all synchronized tables and an update log table that has rows with the unique row identifiers for changed rows (inserted, updated or deleted), for each insert, update, or delete operation and a current update version that reflects the last change to that row. An update request from a device can comprise identifiers for a (sub)set of the data. The update log table can be used to prepare an update package containing this data.

Technologies pertaining to detecting accesses to monitored regions of memory and transmitting data to a protection system responsive to the detecting are described herein. A region of memory that includes objects in an object graph utilized by an operating system to determine which processes to execute and an order to execute such processes is monitored. If a process executing on a processor attempts to write to an object in the object graph, a field that is being written to is identified, and a determination is made regarding whether the field includes a pointer. Based upon whether the field includes a pointer, a type of write desirably undertaken by the object is ascertained, and an object event is transmitted to the protection system that informs the protection system of the type of write.
