Exchange 2007: Monitoring the Exchange Logs file

Posted on 2011-10-23

1) This is related to the Exchange server 2007 in the production environment
2) The instruction is " To monitor the Exchange Logs file; the log file should be greater than 75 GB; if it is less than 75 GB, we have to run the backup ("run now") to the largest storage groups"

3) My questions: i) Why do we have to run backup ("run now") if it is less than 75 GB?, ii) Why do we have to it to the largest storage groups?

    Accepted Solution

    In exchange if we take backup the log files will be purged.
    There is no such thing like if it is less than 75 gb you have to take backup., May be this depends on the person who gave you instruction.
    If your e-mail system goes down you can restore from a backup. This is best when compared to potential damage caused by loss of data.

    Where did these instructions come from? Your boss or the internet?

    The reason why I ask this is because waiting until your log files are 75GB before taking a FULL backup, could be (in my terminology) a CLM, or Career Limiting Move.

    If you wait until you have 75GB of CHANGES to your storage groups before taking a backup, that is rather risky. That is a lot of data that you could lose. I say could, because there are other ways to reduce your exposure to data loss, but that information is not available here.

    I would seriously question the author of those instructions for clarification. Maybe there is more going on here than you are aware of (and thus we are made unaware of here). But to be honest, the instructions do not follow a logical conclusion. If you run backups if the logs are under 75GB, there can never be a point where the logs are allowed to exceed 75GB, since the logs go away after a backup.
