An incremental backup cannot be performed when circular logging is enabled

Error:

CExBackup::backupService:HrESEBackupSetup: Error Number 0xc800020e: An incremental backup cannot be performed when circular logging is enabled.

Cause:

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.

Resolution:

  1. Disable Circular logging on ALL Storage Groups
    1. Disable circular logging on Exchange 2003
    2. Disable circular logging on Exchange 2007
    3. Disable circular logging on Exchange 2010
  2. Restart the Microsoft Exchange Information Store from [Administrative Tools]->[Services].
  3. Run a Manual MS Exchange Database Backup through CyberSecure Advanced (with default options).
