7:75 Description: Nonzero code [] returned from user command. Source: [], Process: startPrePostCmd

Pre/Post scan/backup script causes backup to fail with error code 7:75

Symptoms

This error appears when a subclient has a script configured to run either before or after the Scan operation and/or Backup operation.  There could also be more than one script configured (i.e. Before the scan and after the backup).

Causes

The error code indicates something in the script is failing, and therefore the backup fails.  Since the script is generally provided by another author, the job does not show what portion of the script failed, only that it completed with a nonzero error (0 signifies successful completed, so anything other than 0 is a failure).

Resolution

To find out what has failed, you'll need to speak to the script author, though it can also be a simple permissions issue.

Open the properties of the subclient in question and edit the pre-scan command like below (where 'prescript.bat' is replaced with the entire path of the script that is already there): prescript.bat 1>> C:\std.out 2>> C:\stderr.out

Now, rerun the job that failed.  This will create 2 files that show the output of your script as well as the error message.

• If the error message indicates a permissions issue, ensure that the service account (or account specified) for the subclient has permissions to access and run the script.
  • This is common when the script is on a network share.
• If the error indicates something wrong with the script itself, reach out to the script author.
  • A common example that is easily remedied is where a pre-scan process to stop a service (like SQL)  failed, so the post backup process to start it back up fails (because the service was never stopped).
