Scheduling
Scheduling is at the core of efficient IBM Tivoli Storage Manager operations.
Having a comprehensive and integrated set of schedules allows the server to run
with very little intervention during normal operational periods. IBM Tivoli Storage
Manager scheduling is divided into two categories: administrative scheduling and
client scheduling. The two categories differ in three key areas:
򐂰 Execution location: An administrative schedule performs an action on the IBM
Tivoli Storage Manager server while the client schedule can only execute on
the IBM Tivoli Storage Manager client.
򐂰 Domain privilege: Only an administrator with system privilege can manage an
administrative schedule, while an administrator with policy privileges in the
client’s domain can manage the client schedule. The feature’s granularity can
be very useful when distributing management control across a large
enterprise.
򐂰 An administrative schedule can only initiate an internal IBM Tivoli Storage
Manager command, while a client schedule can initiate an internal client
action such as an incremental backup, or run an external command such as a
shell script or executable.
For both types of schedules, there are four key pieces of information:
򐂰 A command or action to be executed
򐂰 When the command or action executes
򐂰 The period, or window, in which the command or action should start
򐂰 How often the command or action should be repeated
