Backing up an exchange server storage group effectively reduces log files

After the installation and deployment of exchange, after two months of operation, many netizens will find that the space on the C disk is greatly reduced. After the check, they find that the original \ exchsrvr \ mdbdata file is similar to exxxxxxx. log files. We know this is a log file. These log files are also called checkpoint files (chk). They are characterized by a size of 5 MB, for more information about their functions and functions, see the yinjie moderator's Article In-depth analysis of mail storage and log Exchange Server (http://www.5dmail.net/html/2004-8-2/200482153601.htm ).

How can we process these checkpoint files to get more disk space? Maybe you want to manually delete them? I suggest you never have such a plan. Why? In the yinjie article, the relationship between the checkpoint file and the EDB and STM database files of exchange has been described in detail. We recommend that you create an effective backup plan to back up exchange storage groups to effectively reduce log files and increase disk space. I just did my work in this area today, so I caught the process and hoped to help you.

1. First, let's take a look at the situation before restoration:

A. My exchane is installed on the C drive. Currently, 6 is used. 4G Space

B. I opened "\ exchsrvr \ mdbdata" and found many log files similar to exxxxxxx. log:

2. first, choose to open the "attachment"-"" backup "(ntbackup) of Windows server ), I chose to back up all the databases in the "system status" and "Information Store" storage group of the Windows 200 server. (If you only need to reduce log files, you can only select to back up all the databases in the "Exchange" Information Store "storage group. ")

3. Confirm the content you want to back up. Let's start the backup:

4. Backup completed:

5. Let's go back and check whether there are directories that reduce log files and empty disk space:

From the figure above, we can see that our goal has been achieved, the log file is automatically cleared a lot, and the space is also empty for about 3 GB. Of course, backing up exchange is not that simple, but you just want to simply use it. To tell you how to effectively reduce the number of empty disk space for log files.

By the way, I forgot to tell you that sometimes the exchane is service cannot be started normally, because of your carelessness, too many log files, resulting in very little disk space, which is also a reason ..
