ベストプラクティスは、これらの 2 つの操作を標準業務時間外に実行することで、その結果、これらの操作

デルでは、他のシステム操作が実行されない時間にリソースを大量に使用する操作をスケジュールすること
をお勧めします。このアプローチは ウインドウイング と呼ばれ、特定の時間枠（つまり、「ウィンドウ」）の
スケジュールを必要とします。各時間枠には開始時刻と終了時刻が設定されるため、他の操作の実行に干渉

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. The best method is to schedule a time when
you can run the Cleaner on your DR Series system with no other planned processes running. Alternately, another
method lets the Cleaner process on the DR Series system run whenever it determines that there are no active data
ingests.
メモ: Even if no Cleaner schedule is set, but the system detects that there is disk space that can be reclaimed, the
Cleaner process runs. However, the Cleaner will not start until the following conditions are met: it detects that
there are no active data ingests, that two minutes of system idle time have elapsed since the last data file ingest
was completed, and that the Replication process is not running (the Cleaner process runs as a lower system
priority operation than the Replication process).
メモ: Running the Cleaner while ingesting data, reduces system performance. Ensure that you schedule the
Cleaner to run when backup or replication is not in progress.
メモ: The Cleaner Schedule page displays the current DR Series system time zone and current timestamp (using
this format: US/Pacific, Fri Nov 2 15:15:10 2012).
To schedule Cleaner operations on your system, complete the following:
1. Select Schedules → Cleaner Schedule.
The Cleaner Schedule page is displayed.
2. Click Schedule to create a new schedule (or click Edit Schedule to modify an existing schedule).
The Set Cleaner Schedule page is displayed.
3. Select (or modify) the Start Time and Stop Time setpoint values using the Hour and Minutes pull-down lists to
create a Cleaner schedule.
メモ: You must set a corresponding Stop Time for every Start Time set in each Cleaner schedule you create.
The DR Series system will not support any Cleaner schedule that does not contain a Start Time/Stop Time pair
of setpoints (daily or weekly).
4. Click Set Schedule for the system to accept your Cleaner schedule (or click Cancel to display the Cleaner Schedule
page).
メモ: To reset all of the values in the current Cleaner schedule, click Reset in the Set Cleaner Schedule
dialog. To selectively modify values in the current schedule, make your changes to the corresponding hours
and minutes pull-down lists to represent the Start Time and Stop Time you wish to set, and click Set Schedule.
The current Cleaner Status is represented in the Dashboard page in the System Information pane as one of the three
following states:
• Pending—displayed when there is any scheduled window set and the current time is outside the scheduled
window for the Cleaner operation.
• Running—displayed when the Cleaner operation is running during a scheduled window.
