Scenarios when the SQL differential backups get converted to full backups
This article applies to:
- Product edition: Phoenix
Overview
When a differential backup is triggered, the agent requests information about databases that are updated. Phoenix backs up the differential data and creates a snapshot in your storage. During the differential backup, the changed blocks (delta) from MDF & NDF files are backed up, but the entire LDF files are skipped. This document lists multiple scenarios due to which the Differential SQL backups gets converted to Full backups.
Scenarios
- SQL differential backups can also run as full because of a backup start time mismatch. See SQL differential backup runs as full due to backup start time mismatch for more information.
