Hello all,

I am trying to generate a farm backup from our SharePoint environment and have tried the following (main code) : 

Add-PSSnapIn "Microsoft.SharePoint.PowerShell"
Set-ExecutionPolicy -ExecutionPolicy "Unrestricted" -Force

Backup-SPFarm -directory $farmBackupPath -backupmethod Full

In the log file, I see this error :

FatalError: Object Search Service Application failed in event OnBackup. For more information, see the spbackup.log or sprestore.log file located in the backup directory.
InvalidOperationException: Failed to set request to pause search application

I have done some google search and found this:

But this did not help resolve the issue. 

Has anyone encountered this problem and found a different solution ?

Thank you all,

Mya

Hi Mya,

As I understand, you encountered the error when doing farm backup in SharePoint 2013.

You could provide read/write permission to search service account on backup directory.

You also could do a full crawl in the search service application, then do the backup to check if it can work.

And you could check if you have do the back correctly according to the article below.

You also could run the backup by other methods.

Hi,

Pause the Search service application.

Run the Back up Script.

Resume the Search service application.
