Abstract
A system identifies and causes transmission of differential data generated during device migration. An administrative server accesses a first backup snapshot of a retiring client device. The first backup snapshot includes a set of files stored in the retiring client device during a first checkpoint. The administrative server transmits the set of files in the first backup snapshot to a replacement client device. A cloud server stores the first backup snapshot and a second backup snapshot of the retiring client device. The second backup snapshot is created during a second checkpoint occurring after transmission of the set of files. The cloud server receives an indication that a user has logged on to the replacement client device and causes a transmission of differential data to the replacement client device. The differential data includes at least one file in the second backup snapshot that is not included in the first backup snapshot.
