How can I safely remove orphaned exchange 2003 logs?

Posted on 2011-05-03
Last Modified: 2012-05-11
I have windows 2003 enterprise and exchange 2003 enterprise with 5 information stores.
I used to have one large information stare and broke it into smaller parts.
3 information stores are used for user accounts, and one is used for an offsite journalling service that basically forwards emails to an external site, but it is never needed to be backed up.

The problem is I have accidentally created some information stores in the same folder. I have over 120 gigs of logs files for over the past year.

I have checked the information stores and they are being backed up, and I need to clear out the disk space.

Is it safe to remove all log files older than the "oldest" successful backup?  I also believe I need to move the stores to individual folders to keep the logs from being jumbled together.

Thanks for your help

    Sounds a little like you are unsure which log files are real/active etc...

    I suggest you enable Circular Logging on all of the stores.  Restart the Information Store service and then all the logs should get flushed out (removed) except for maybe up to 5 log files per Store.

    If there are a lot of log files remaining then I would wait some time.  With circular logging it will rotate up to 5 log files per Store.  So after some time (hours?)  of activity only the active log files should have recent timestamps.

    You can then delete any obviously old log files.

    Then you can disable the Circular Logging and restart the Information Store service again (to make the change active).

    Why isnt your backup flushing the logs? You need to run a full backup.

    The emails were generated from an information store that doesnt need backed up, but is being backed up now. It was for an offsite journaling service.
    Backing up the store cleared out the logs! Thanks!
