Update credentials for a network path in the backup plan:
- Open backup management console.
- Navigate to All devices and select the affected device.
- Find the affected backup plan and click the gear icon to edit backup plan settings.
- In Where to back up, click on the "key" icon and specify new credentials for the network destination in "domain/user" format
- Save changes.
Backups should run successfully now.
