After an upgrade from Backup Exec 2012 to Backup Exec 2014, NDMP backups that have a backup method of Level 1 are incorrectly labeled as incremental instead of differential.
To change the label:
- Click the Backup and Restore tab
- Right-click the server name and then click Edit Backup to open the job
- Without making any changes to the job, click Save. The job should correctly display as a differential job.
