Hi @Manisha 

It looks like there might be a Job Error Threshold rule that has been enabled on the Commcell.

Pasted below is a screenshot to help you navigate to the panel where this rule has been set\enabled.

You can try disabling the rule to see if it helps.

Here’s a BOL link for further information, please let me know if you need any further assistance.

Thanks

This helps.. Thanks.

If it is any impacts for the backup after disable this rule?

Shouldn’t be.  It won’t change the backup itself, only how it is marked.

As per the docs:

Use this dialog box to create and enable error decision and threshold rules for an agent to control the status of backup jobs that occur at the CommCell and client computer level.

Thank you mike.

Somewhat late to this thread, but here it goes 

It is interesting this happens for one of our NAS shares, but not all. And it only happens on incremental backups, not on full backups.

I have disabled the threshold temporarily, will take a look tomorrow to see what the backup job status show.

Thanks for the responses above!
