Blackout Windows

Blackout windows allow the Commvault® administrator to designate periods in which operations do not run. These rules can be set at the CommCell® environment or at the server plan level. For example, if the plan backup window prevents backups from 1 p.m. to 6 p.m., no backups will run between 1 p.m. to 6 p.m. for all clients covered by that protection plan.

CommCell® Level Blackout Window

Configuring a blackout window at the CommCell environment level prevents scheduled or manual backups from running. This can be useful to prevent backups from running during peak hours, leaving all client server resources to the users.




To create a CommCell® level blackout window

1 - Expand Manage | Click System.

2 - Click Blackout window.



3 - By default, no blackout windows are defined. Click to add a blackout window.



4 - Provide a descriptive name.

5 - Select jobs to prevent from running.

6 - Select the days during which the window is applied.

7 - Highlight in blue the hours during which operations are prevented from running.



Plan Level Backup Window

A backup window can be defined in a server plan. This dictates when the backups are allowed to run. By default, backups can be conducted all day on every day. To prevent backups from running during specific hours, edit the server plan's backup window.




To configure plan level backup window

1 - Expand Manage | Click on Plans.

2 - Click the plan name.



3 - Click the backup window definition link.

Full backup window – Define when full backups are allowed to run

Backup window – Defines when other backup types are allowed to run (i.e. incremental, differential, etc.)
