Types of restore operations The following restore operations are available by choosing either "Restore Volume ..." or "Restore Selected Files ..." from the file menu. Select these menu items and press PF2 for the specific operations that are available to each. Restore a volume save set (initializes the output disk) - This option writes the save set data onto the output disk after it erases the existing data on the output disk. You are prompted to confirm this operation. Restore file(s) from a save set - This option reinstates one or more files from a save set to a specified location on output disk. You can use this option to add the contents of a volume save set to a larger disk. Restore an incremental save set - This reinstates files copied from an incremental save operation.
