The Tivoli® Storage Manager central scheduler allows client operations to occur automatically at specified times.
In order to understand scheduling with Tivoli Storage Manager, several terms need to be defined:
When creating a schedule definition on the Tivoli Storage Manager server, schedule actions that you can take include incremental, selective, archive, restore, retrieve, image backup (does not apply to Mac OS X), image restore (does not apply to Mac OS X), command, and macro. The scheduled action that is most frequently used is incremental with the objects parameter left undefined. With this setting, the Tivoli Storage Manager client performs a domain incremental backup of all file systems defined by the client domain option. A schedule definition using the command action allows an operating system command or shell script to be executed. When automating tasks for Tivoli Storage Manager for Data Protection clients, you must use command action schedule definitions which invoke the command-line utilities for the "Tivoli Storage Manager for" application.

Event | Window start | Window end | Actual start (just an example, times vary) |
---|---|---|---|
1 | 12:00:00 | 12:30:00 | 12:05:33 |
2 | 13:00:00 | 13:30:00 | 13:15:02 |
3 | 14:00:00 | 14:30:00 | 14:02:00 |
and so on |
The variation in actual start times is a result of the randomization feature provided by the Tivoli Storage Manager central scheduler which helps to balance the load of scheduled sessions on the Tivoli Storage Manager server.
