Exchange 2003 (cluster) SP2 runs on Windows Server 2003 SP1. The log files can't be flushed after Symantec BackupExec 10d full backup. I've tried selection of all individual mailboxes+all public folders or selection of information store as a whole. I also tried to use Windows' own bakcup utility for a full backup on Exchange (infomation store). Neither truncated log files. What should I do to truncate the logs? Is it helpful and safe if I enable "Remove log files" in Exchange Properties (Currently "Enable subject logging and display" is selected; "Enable message tracking" is selected, but "Remove log files" is not selected)? Is there any other way to flush the log file besides changing Exchange logging scenario? Thanks.
