• Check: compare the contents of the backup and current device state. Check fails
if the contents do not match, and passes if they match.
This view also shows the newly added, factory-reset devices, with IP address
192.168.2.10 (see bottom-most device in
Figure 30
). Any of the existing
backups can be deployed to this device. There can only be one factory-reset
device visible at a time, otherwise IP address conflict would occur.
