DURATION hh:mm

Specifies a maximum time for a backup command to run. If a backup command does not complete in the specified duration, then the backup stops. Without the PARTIAL option, the backup command is considered to have failed if it does not complete in the specified duration, and RMAN reports an error. If the backup command is part of a RUN block, then subsequent commands in the RUN block do not execute.
