Exchange Backup not flushing logs

We're backing up Exchange 2003 with Backup Exec 11d.

The selection list includes 'Microsoft Information Store' and the backup job is configured as follows:

Backup Method: Full - database & Logs (flush committed logs)
Enable the restore of individual mail messages and folders from the IS backups
Perform consistency check before backup using MS VSC Service
Continue backup is check fails

We're gettiing successful backups each night, however, the Exchange system manager shows last backup date was 14/01/2009 and the transaction logs are building up.

You get this sometimes without any reason

Try and do an NTBackup including the Exchange - this will ofetn flush out the logs and then allow Backup Exec to do its job properly

Also ensure that u are not using the AOFO option for the exchange job
that interferes with the flushing too
you might wanna run the ESEUTIL and ISINTEG to check the exchange databases

Refer to the following articles for more information

Exchange Transaction Logs do not get flushed after a full Backup of Exchange Information Store when used with Advanced Open File option.

After a backup of an Exchange 2000 Information Store, the transaction logs are not flushed, even if the backup method was set to "FULL (flush committed logs)" or "INCREMENTAL (flush committed logs)".

After performing a backup of Exchange 2000 or Exchange 5.5 with "flush logs" selected, the log files are not flushed although "Circular" logging is disabled.

Thanks. Knew there were issues with AOFO, but thought it just caused the backup to fail completely.

I've turned off AOFO. Will see how it goes over the weekend...

Created a separate job for Exchange with AOFO disabled. Backups are succeeding and logs are flushing as expected.
