Normal WFBS Security Server operations will use up disk space that may range from as low as 1.2GB up to 6.0 GB depending on the usage. However, under some occasions when the Security Server is managing a lot of agents including the Messaging Security Agent, a disk usage of up to 9GB may occur.
For example, 9GB usage may occur when the Security Server of WFBS 6.0's Messaging Security Agent is installed, Smart Scan mode is enabled, and debugging is also enabled, all at the same time.
Lack of free space may cause the Security Server to stop updating. To regularly free up disk space, you can use the Disk Cleaner tool to clear up unused WFBS files such as backup files, log files and unused pattern files.
Access the Disk Cleaner (TMDiskCleaner.exe) tool from the ..\Trend Micro\Security Server\PCCSRV\Admin\Utility folder in the Security Server.
You can use the Disk Cleaner through any of the following:
- Double-click the TMDiskCleaner.exe file.
- Click Delete Files to start the cleaning of unused files.
- Once the cleanup process is finished, click Save Log.
In UI mode, all cleaned files cannot be restored.
- Open a command prompt window.
- Run the following command:
TMDiskCleaner.exe [/hide] [/log] [/allowundo]
/hide - Execute tool in the background.
/log - Save the DiskClean.log file to the current folder. This parameter only works when "/hide" is set.
/allowundo - Move files to the Recycle Bin only.
If you want to run the Disk Cleaner in regular intervals, you can use Windows Scheduled Tasks.
- Go to Start > Programs > Accessories > System Tools > Scheduled Tasks.
- Double-click Add Scheduled Task.
- When the Scheduled Task Wizard window appears, click Next.
- Select TMDiskCleaner.exe.
- Specify the frequency of the cleanup, the time, and the user account that will be used to run the tool.
- Go back to the Scheduled Task window, right-click TMDiskCleaner and select Properties.
- On the Run field, specify "/hide /log" as shown below.
- Click Apply.
The following directories will be cleaned:
- <SS>\PCCSRV\TEMP\* (except hidden files)
- <SS>\PCCSRV\Virus\* (Delete quarantined files older than two weeks, except NOTVIRUS file)
- <SS>\PCCSRV\ssaptpn.xxx (keep the latest pattern only)
- <SS>\PCCSRV\lpt$vpn.xxx (keep the latest three patterns only)
- <SS>\PCCSRV\icrc$oth.xxx (keep the latest three patterns only)
- <SS>\DBBackup\* (keep latest two subfolders only)
