By default, the preselected backup type is incremental. However, you can change the preselected backup type.
After you change the preselected backup type, a full backup runs automatically before the new preselected backup type runs.
Note
If a preselected job fails or is killed during the Archive Index phase, the next job will convert to a full backup.
