When you run a backup, create a backup schedule, or create a selection list, you have the option to check an Exclude System State checkbox to back up data and not include OS protection. If you are backing up an aliased client, you must decide whether to include or exclude the system state. Keep the following in mind:
• DO NOT EXCLUDE the system state on the client that contains the operating system volumes (this is typically the C: volume).
• For all other client aliases that do not include the OS volume, do NOT include the system state.
• Only one client alias can include the system state.
• The restore fails if the system state is not included in the OS volume and if the system state is included in the client aliases that do not include the OS volume.
Important for Windows clients: The backup must contain the boot disk and any other system critical volumes to use the integrated bare metal recovery and Windows instant recovery features. Be sure one of the aliased clients contains all of these disks to use these features
