In some examples, a computer system may receive a data object including object data. For example, the system may be one of three or more systems located at different respective geographic locations. The system may determine a plurality of chunks by dividing the object data into a plurality of data chunks based on a total number of the systems and determining a parity chunk. The system may send some of the chunks to the other systems, while maintaining a complete instance of the object data at the first system. The system may associate a time with the object data based on receiving the data object. Additionally, the system may associate a time threshold with the complete instance of the object data. For example, the time threshold may indicate a time at which the complete instance of the object data is to be deleted from the system.
