Question

Backout window question.


Forum|alt.badge.img+5

I scheduled FS backup to run at 6pm and created a blackout window between 6am and 5:50pm for weekdays.

 

This is a large backup (many TBs) and it wont be finished for weeks. The idea is that the running backup job that started at 6pm will run to 6am the 2nd day. Then it goes into queue state and resumes automatically at 6pm. 

However backup jobs continue to run after 6 am in the morning and I have to manually stop it. After some research I found below. 

https://documentation.commvault.com/11.20/blackout_window.html 

 

"If any operations are already running within the time window, then the operations are not affected. The window rules are applicable only to the new operations that start after the time window." 

 

Is there a way to achieve what I need?

Hi ​@Boyi ,

 In Commvault, blackout windows do not affect operations that are already running when the blackout period begins. These operations will continue to run until completion or until manually stopped. This is why your backup job continues past 6 AM despite the blackout window.

To achieve the behavior you're looking for, you might consider using job management settings to limit the total running time of the job to align with your blackout window.

Unfortunately, there is no automatic feature in Commvault to pause and resume ongoing jobs based on blackout windows.

 

Thanks,

Keshika

Hi ​@Keshika Bisht,

 

Thank you for the reply.

I actually found a way automate this process. In the advance setting of backup schedule there is a place to set total run time for a backup and there is an option to kill the job when the time expires.

 

Kind regards,

Boyi

Well killing the job is not the most elegant solution. I do see enough use-cases for an option in a blackout window that results in running jobs to be paused when the window kicks in. I would open a CMR for it.
