When you use BRMS, you can do backups, restores, and media moves without having to be nearby when they occur.
When you schedule a policy to run, keep in mind that only the items that are scheduled to be backed up on the day you run the policy will be backed up. For example, you have a backup policy that includes the library MYLIB. In the policy properties, you have MYLIB scheduled to be backed up every Thursday. If you schedule the policy to run on Thursday, MYLIB will be backed up. If you schedule the same policy on any other day, MYLIB will not be backed up.
Also, be aware that some operations (such as a full system backup) require that your system be in a restricted state when they run. With BRMS, the interactive console monitor allows you to submit a backup job, either scheduled or directly, to the interactive session running on the system console. A system operator can use the interactive system console session to monitor the progress of the backup and respond to tape mount messages. When you schedule a backup using the interactive console monitor, you will see the instructions for how to start the console monitor.
If you choose not to use the interactive console monitor and no one will be present to process commands as the backup runs, then you must ensure that your backup can run without intervention. A restricted state backup not using the interactive console monitor can also be scheduled as long as the backup can run unattended.
