ISSUE: Error Number 0xc800020e: An incremental backup cannot be performed when circular logging is enabled

Servosity Professional: All
OS: Windows

When performing a MS Exchange transaction log backup, the following error message is received in the backup report:

Backup Logs  No.  Type  Timestamp  Backup Logs 1 Info YYYY/MM/DD hh:mm Start [ Windows platform (---), Servosity 5.x.x.x ] 2 Info YYYY/MM/DD hh:mm Start running pre-commands 3 ... ... ... *  Error  YYYY/MM/DD hh:mm CExBackup::backupService:HrESEBackupSetup: Error Number 0xc800020e: An incremental backup cannot be performed when circular logging is enabled

The message suggests that a transaction log backup cannot be performed if the corresponding information store has circular logging enabled.

To resolve the issue, please disable circular logging of the corresponding information store, and restart the "Microsoft Exchange Information Store" service afterward.

Furthermore, please also perform a full MS Exchange server backup instead of transaction log backup straight after disabling circular logging. This would ensure that the data on server are all backed up properly.
