You have an application-aware backup of an SQL instance.

After a while, you add another SQL instance to your SQL server.

Backup completes with warning, second instance is not backed up:

Credentials for MS SQL are stored per instance, not populated automatically to new instances.


To fix the issue, use one of these methods:

1. Specify credentials manually:

  1. Go to Devices -> Microsoft SQL.
  2. Click the device name:
  3. Click the instance name:
  4. When prompted for credentials, provide credentials of user with sysadmin role (specify as domain\user if it's a domain user):

2. Use custom script to reset all credentials as described in KB 61551.
