What is the process of copying data back and forth between devices known as?

The process of copying data back and forth between devices is best described as mobile device synchronization. This term specifically refers to keeping data consistent between a mobile device and another source, such as a computer or cloud service. When synchronization occurs, it ensures that information like contacts, calendars, emails, and files remain the same across the devices, making it easy for users to access recent information regardless of the device they are using.

In this context, synchronization is not just a one-time process but an ongoing one that automatically updates changes between the devices, allowing for real-time access to data. This is particularly important in today’s mobile landscape, where users often switch between devices regularly.

While file transfer refers to the act of moving files from one location to another, it does not inherently imply that updates on one device will automatically reflect on another. Data migration typically describes the process of moving data from one storage location to another, often involving substantial changes to how the data is used or stored. Backup and restore involves creating copies of data for safe keeping and later retrieval, which is a different concept than maintaining synchronized copies of data across multiple devices.
