If the promoted host is not an automatic backup host, it will only perform the unique primary host automatic backup functions during the automatic backup window. It will not backup managed volumes. If the promotion occurred while the original primary host was performing one of the three unique autobackup functions, the promoted host takes over from the point where the original host left off.

Example: If the original primary host had just completed backing up the CDSs before it failed, then the promoted host will not backup the CDSs again, but will begin by moving data set backup versions from ML1 to tape.
