Windows server 2008 scheduled disk defrag

When defrag is finished analyzing and defragmenting the volume, it displays the analysis report, the defragmentation report, or both reports, and then exits to the command prompt.

Running the defrag command and Disk defragmenter are mutually exclusive. If you are using Disk defragmenter to defragment a volume and you run the defrag command at a command-line, the defrag command fails. Conversely, if you run the defrag command and open Disk defragmenter, the defragmentation options in Disk defragmenter are unavailable.

The defragmentation process runs scheduled task as a maintenance task, which typically runs every week. As an Administrator, you can change the how often the task runs by using the Optimize Drives app.

When run from the scheduled task, defrag uses the below policy guidelines for SSDs:. Traditional optimization processes. Includes traditional defragmentation , for example moving files to make them reasonably contiguous and retrim. This is done once per month. However, if both traditional defragmentation and retrim are skipped, then analysis isn't run.

Nick Kavadias Nick Kavadias That's my point, no special needs here just wondering what the big deal seems to be when folks say that windows defrag isn't good enough. Maybe they all work for Diskeeper with one k ;- — user Diskkeeper lets you defrag open files, not sure about the others.

Save your money on defrag software to buy better hardware instead. Funny, if I went SSD money would not be the concern ;- — user Ancient question, I know Leonard Leonard 65 7 7 bronze badges. Sign up or log in Sign up using Google.

Once invoked, the initial Check Disk dialog will appear providing two options as illustrated below:. If neither of the options are selected when the Start button is pressed Check Disk will only report, but not attempt to fix errors.

In order for Check Disk to repair errors and recover bad sectors during the scan the Automatically fix file system errors and Scan for and attempt recovery of bad sectors toggles must be selected respectively. If the disk drive contains open files, Check Disk will be unable to fix errors located during the scan and will display a dialog warning you of this fact. This warning dialog will also provide the option to have the check run on the next system reboot before any files are opened.

This marks the disk as dirty forcing Check Disk execution at system startup. This setting may also be specified from the command prompt as follows:. The Check Disk process may also be initiated from the command prompt using the chkdsk command combined with the designator of the drive on which the scan is to be performed.

In addition to performing the same functions as the graphical version of Check Disk, the command prompt version also provides more detailed disk analysis and repair reports. The chkdsk utility accepts a number of command line options which govern the tasks performed during execution.

These options are outlined in the following table:. Figure B Click the image to enlarge. If this mechanism is selected, here are guidelines for deploying GPOs for defrag: Go very granular in the organizational unit structure with different schedules to distribute the workload. Consider running this on client PCs. Be aware of multiple iterations of defragmentation where SANs are in use. Consider consolidated effects of virtual machines.
