Create Client Profile Wizard - System

Field

Description

Application UI

In this section, you can specify whether the users of the managed client computers can launch PerfectDisk Client User Interface (UI). Choose from the following two options:

• Allow users to launch the PerfectDisk UI - This is the default option. Users will be able to launch the PerfectDisk Client application on their machine.

• Disable launching of the PerfectDisk UI - Choose this to disable the launching of PerfectDisk Client UI by the users. PerfectDisk would still do its task in the background, but users of the machine would not be able to launch the application.

Logging

In this section you can specify where PerfectDisk should log information about defragmentation operations. You can select the following options:

• PerfectDisk Log - Choosing this option will log the defragmentation operations in the Log Viewer window of the PerfectDisk Client.

• Windows Application Event Log - Choosing this option will log the events in the Windows Event Viewer.

See PerfectDisk Help for more information on log.

Power Options

In this section, you can configure the behavior of PerfectDisk Clients when the computer is on battery power. You can select the following options:

• Stop any current optimization passes while on battery power - This assures that PerfectDisk will detect when a computer is running on battery power and will stop any currently running defragmentation pass.

• Do not start a optimization passes while on battery power - This assures that PerfectDisk will detect when a computer is running on battery power and will not start a defragmentation pass during that time.

CPU Priority for manual and scheduled optimization

In this section, you can raise or lower the CPU priority at which PerfectDisk runs defragmentation. While PerfectDisk actually uses very little in CPU resources, it still allows users that have CPU bound systems to feel comfortable that they can run PerfectDisk at a lower priority and not impose additional CPU load on the system.

CPU resource are adjusted to lower or raise the CPU priority by specifying these options:

• Lower than other applications - This option ensures that PerfectDisk runs defragmentation passes at a lower priority than other processes.

• Same as other applications - This option ensures PerfectDisk runs defragmentation passes at the same priority as most other processes. This is the recommended option and is selected by default.

• Higher than other applications - This option ensures PerfectDisk runs defragmentation passes at a higher priority than other processes. When selected, PerfectDisk may delay other processes.

Minimize Disk Usage for manual and scheduled optimization

If you select Run optimization at lowest disk priority option, PerfectDisk automatically detects if a drive is "busy" and reduces its disk I/O usage during that time. This allows PerfectDisk to run on very busy disks without imposing any additional load on the disk. This may result in longer defragmentation passes.

Volume Shadow Copy (VSS) compatibility

PerfectDisk can be configured to detect if VSS is enabled on a drive and to take appropriate action. You can specify from three different options:

• Do not optimize drive - PerfectDisk can also be configured to stop the defragmentation if any shadow copies exist. In this situation, PerfectDisk will NOT defragment the drive at all.

• Optimize using VSS compatible mode. Minimize disk changes to X% of disk - By default, if VSS is configured on a drive and the cluster size is less than 16k, then PerfectDisk will defragment in VSS compatible mode. When configured to defragment in VSS compatible mode and the drive cluster size is less than 16k, PerfectDisk will limit the number of files "moved" during the defragmentation pass so that purging of Shadow Copies/Restore Points is minimized.  For VSS enabled drives where the cluster size is 16K or larger, PerfectDisk will defragment drives normally.

Note: When PerfectDisk defragments a drive in VSS compatibility mode it may not defragment files/free space as completely as it normally does.

• Optimize drives normally - If VSS is configured on a drive and the cluster size is less than 16k then PerfectDisk can be configured to not defragment the VSS enabled drive at all or to defragment the VSS enabled drive normally. If PerfectDisk is configured to perform normal defragmentation, it may result in Shadow Copies/Restore Points being purged as defragmentation is performed.
