Diskeeper 10 User's Manual

34 Diskeeper Operation
You can also set exclusion times when the Smart Scheduling option will be prevented from scheduling a
defragmentation run. When Smart Scheduling is selected, the Days drop-down option list will be limited to
these times:
Except Everyday
Except Weekends
Except Weekdays
Except Monday
Except Tuesday
Except Wednesday
Except Thursday
Except Friday
Except Saturday
Except Sunday
You can use the Start time: and End time: drop down lists to further define times when the scheduling of
automatic defragmentation runs will not be allowed. For example, a schedule set like this:
Type of Schedule
Smart Scheduling
Start Time
Which Days
Except Weekdays
End Time
1:00 am 3:00 am
will allow Diskeeper to automatically determine how often to run, but will also prevent it from running between
1:00 am and 3:00 am on weekdays (i.e., when your nightly backup is running).
Screen Saver Mode
When enabled, Screen Saver mode automatically starts defragmenting the selected volumes any time the screen
saver starts on your computer. The defragmentation operation is paused whenever keyboard or mouse activity
is detected on the computer. This option is available under the Schedule type: drop-down list in Job Schedule
page of the Primary Defragmentation Job Properties dialog.
If you only have a single volume selected for Screen Saver mode, the defragmentation operation is re-started at
the logical “beginning” of the volume each time the screen saver re-starts after being interrupted (by keyboard
activity, for example).
When more than one volume is selected for Screen Saver mode, the volumes are handled in a round-robin
manner. If a defragmentation pass is stopped, the operation resumes on the next volume when the screen saver
starts again. For example, if you select volumes C and D to be schedule with Screen Saver mode, when your
screen saver starts, Diskeeper begins a defragmentation pass on volume C. If that pass is interrupted, and then
the screen saver starts again, Diskeeper will begin a pass on volume D.
If the screen saver has not been interrupted after Diskeeper completes the defragmentation pass on each of the
selected volumes, Diskeeper is automatically scheduled to re-start the defragmentation operation in one hour.
Because of the “start and stop” nature of the Screen Saver mode, it is not recommended on volumes that are
heavily fragmented, unless you expect the computer's screen saver to be on for several hours. In cases where
your screen saver activity is only for short periods of time, a thorough manual defragmentation or scheduled Set
It and Forget It defragmentation should be performed before running Diskeeper in Screen Saver mode.
