Hello,
Are you backing up Information Store also ?
The transaction logs are flushed only when you are taking a full or incremental backup of the Information Store of Exchange 2003. Individual mailbox backup will not flush the transaction logs.
If you are backing up Information Store and still if the logs are not being flushed then the solution is given below.
Backup Exec sends signals to ESE in Exchange to flush the logs. It has been seen that, the ESE in Exchange receives the command from VERITAS Backup Exec to flush the logs, but ESE does not respond to the command, because it considers the logs as necessary.
This can be a sign of some corruption, especially if no logs at all are being flushed for a long time and there's a massive accumulation of logs within Exchange 2003. This condition can also occur, if some other utility has marked a logs as being in use. But in fact, they are not. This condition will prevent Exchange from flushing the logs.
To resolve the issue:
1. Stop all Backup Exec services
2. Backup the Exchange using NTbackup. Running a backup with NTBackup will flush the logs.
3. Start Backup Exec services.
4. After this initial purging of the logs, Backup Exec will subsequently flush the logs when Full and incremental backups are done.
The above steps will resolve the issue, if the logs are not flushed when you do a full or incremental backup of Information Store.
Hope this helps you.
Regards
