volumes for file access frequency on an ongoing basis in to determine which files are requested most often.
Special analysis techniques prevent Diskeeper from being “fooled” by files that have been recently accessed.
Using newly-developed technology, Diskeeper sequences the files to take best advantage of both the logical
characteristics and physical characteristics of the volume. The sequencing process is integrated with
background defragmentation, so it’s virtually transparent to you.
Note that I-FAAST Defragmentation Jobs are intended to be used in conjunction with Primary or Secondary
Defragmentation Jobs, and these defragmentation jobs will follow rules established by the I-FAAST engine
based on the I-FAAST evaluation of the volume.
Also note that since I-FAAST defragmentation is an ongoing process based on conditions and activity patterns
detected on your specific volumes, it can take up to a week or more for the full benefits of I-FAAST to become
apparent.
When you first enable an I-FAAST Defragmentation Job on a volume, Diskeeper evaluates the volume to
determine if the volume will benefit from I-FAAST defragmentation. In order to gather the most accurate data
about your volumes, the I-FAAST evaluation should be done when no other activity is occurring on the
computer. Any currently-running defragmentation jobs will be stopped before the I-FAAST evaluation is
performed. Manual Defragmentation Jobs will not be resumed, but Primary or Secondary Defragmentation Jobs
will resume at their next scheduled starting time.
After the evaluation has been completed, if any of the selected volumes will not benefit from running I-FAAST,
a message is displayed to explain why, and you are given the choice of enabling I-FAAST Defragmentation or
not on those volumes.
It should be noted that the I-FAAST evaluation creates a hidden \Diskeeper folder at the root level of each
volume on which it is run. This folder contains data files used by I-FAAST and should not be deleted when I-
FAAST is enabled.
After the evaluation, the General properties page of the I-FAAST Defragmentation Job Properties dialog
shows the potential file acceleration from running I-FAAST on the volume and other useful information.
I-FAAST intelligence allows Diskeeper to adapt to changing situations—so if the demands on a given system
change, Diskeeper automatically adjusts its behavior accordingly.
Setting an I-FAAST Defragmentation Job Schedule
Keep in mind that I-FAAST (Intelligent File Access Acceleration Technology) Defragmentation Jobs are
designed to run along with either Primary or Secondary Defragmentation Jobs. I-FAAST Defragmentation Jobs
are intended to supplement regular scheduled defragmentation jobs, not replace them. As the Primary and
Secondary Defragmentation Jobs run, they will follow rules established by the I-FAAST engine based on the I-
FAAST evaluation of the volume.
Follow these steps to enable and schedule an I-FAAST Defragmentation Job on one or more volumes:
1. Click I-FAAST Defragmentation Job Properties on the Diskeeper toolbar or select it from the Set
It and Forget It task list in the Quick Launch Pane.
2. Select one or more volumes in the dialog displayed and enable the Enable I-FAAST to run on the
selected volumes check box on the Job Schedule properties page. Note that this option may not be
available when certain volumes are highlighted. See below for more information.
3. Use the options provided to specify how often you want the I-FAAST Defragmentation Job to run (daily or
weekly), and starting and ending times for the job.
4. Click OK to save the schedule you have set and close the I-FAAST Defragmentation Job Properties dialog
or click Apply to save the schedule without closing the dialog. Click Cancel to close the dialog without
saving the schedule.
