CExBackup::backupService:HrESEBackupSetup: Error Number 0xc800020e: An incremental backup cannot be performed when circular logging is enabled.
Circular logging is enabled, which means that Exchange server writes out to only 4 transaction logs. Circular logging commits and recycles the logs to save disk space.
Circular logging is used for specific environments where an incremental/differential backup or transaction log backups are not required.
- Disable Circular logging on ALL Storage Groups
- Restart the Microsoft Exchange Information Store from [Administrative Tools]->[Services].
- Run a Manual MS Exchange Database Backup through CyberSecure Advanced (with default options).
