  • exchange transaction log files

    Hi ,

    We are using Windows Server 2012 and Exchange 2013 is installed on it.

    Now my in my database folder , files are getting increasing very speedily somehow since last 3 days...it occupied 10 gb in 2 days and my drive is getting full rapidly...

    I search and found windows server backup can help but same time many users are saying , even though windows server backup will not purge the log files..So what will be the best way to take the backup and truncate log files..

    Also what could be the reason behind this , suddenly the transaction log files are get increasing ...

    thanks..

    The reason the transaction logs are growing is that Exchange is not being backed up by an Exchange Aware backup application. If they were previously getting deleted after backup, look for changes in the backup software.

    As you have already found, Windows Server Backup is Exchange Aware, so should truncate the log files for you:

        If you are willing to take the risk of database loss, you could enable circular logging, but I would not recommend it. Suggest you investigate event logs etc to find out why the log files are not being deleted

            Hi ,

            I tried once more and now the log files are trunkate automatically ...but still the space of Mailbox folder is getting filling 1 gb per hour...why its increasing this much rapidly..

            What could be the reason..Does someone trying to send us spams or making attacks on us...

            How to identify if someone is attacking on us..

            Thanks...

              That is a totally separate issue - you will need to investigate the message tracking logs (or possibly talk to your users)

                  Hi, just a thought. You could create a couple of new mailbox databases, large mailboxes, small mailboxes or something and then move users to them. Also keep an eye on the database sizes. If you notice the old database stop growing and the new database start to grow when the problematic user is moved then you could isolate the problem.

                            (sigh) Why do I feel we are going around in circles here?

                            Moving them to a PST won't help reduce the log file size. The log files are generated when email comes into the mailbox database.
                            To reduce the size of the log files, increase the frequency of backups (using an Exchange Aware backup application)

                              Thanks for your quick reply.. I am taking a daily backup using WSB but the thing is earlier the log files were not creating this much frequently , earlier in a full day , it was consuming 2 gb in full 24 hours but now its consuming 20gb in 24 hours...so what could be the reason for this...

                              Thanks...
