A plurality of master desktop images for a plurality of users are stored at a plurality of geographically diverse data centers. At a first one of the data centers, a virtual desktop is constructed for a remote client. The virtual desktop is constructed from a given one of the master desktop images at the first one of the data centers and an individualized delta image for a user associated with the remote client. When it is determined that the remote client is at a geographical location wherein the first one of the data centers is not the closest one of the data centers to the remote client, the virtual desktop for the remote client is reconstructed at a second, closest, one of the data centers. The virtual desktop is reconstructed from a given one of the master desktop images at the second one of the data centers and the individualized delta image for the user associated with the remote client. A copy of the individualized delta image is moved from the first one of the data centers to the second one of the data centers to facilitate reconstructing the virtual desktop.
