The goal behind planning and scheduling operations is to run the Cleaner
and replication operations at times when they do not overlap each other so
the system can perform each operation independent of the other.
The best practice is to run these two operations during non-standard business
hours, so that they do not conflict with any of your other backup or ingest
operations. In short, efficient scheduling maximizes the best use of system
resources.
Dell recommends scheduling resource-intensive operations during specific
time periods when no other system operations are being performed. This
approach is called windowing, which requires scheduling a specific block of
time (a "window"), each with a set point start and finish time for performing
data ingests, replication, or space reclamation operations.

Creating a Cleaner Schedule

Performing scheduled disk space reclamation operations are recommended as
a method for recovering disk space from system containers in which files were
deleted as a result of deduplication.
To schedule Cleaner operations on your system:
NOTE:
The Cleaner Schedule page displays the current DR4000 system time
zone and current date and time for reference.
1 Select ScheduleCleaner.
The Cleaner Schedule page is displayed.
2 Click Schedule.
The Set Cleaner Schedule page is displayed.
3 Select time values to create Start Time and Stop Time setpoints (using the
hour and minutes pull-down lists) for creating Cleaner schedules.
NOTE:
You must set a corresponding Stop Time for every Start Time in each
Cleaner schedule you set. The DR4000 system will not support any Cleaner
schedule that does not contain a Start Time/Stop Time pair of setpoints.
