Scheduler

The Scheduler page displays all replication, replication throttle, e-mail report, healthchecks, and space reclamation events scheduled to occur in a selected time period. To view scheduled replication events for NAS shares or VTL partitions, click the arrow next to the folder to display all shares or partitions.

Note: The thickness of the bars on the schedule view varies based on the type of event and the selected time frame. Healthcheck events have an estimated span of 6 hours. Space Reclamation events have an estimated span of 16 hours. All other open-ended events have a default span of 2 hours.

To add or edit a scheduled event:

1. On the Scheduler page, adjust the schedule view to display the time period when the event will occur (see Viewing Scheduled Events). Then do one of the following actions (see Figure 3):

   Add a New Event

   • To add a new event, click and drag on the schedule in the row for the type of event to add. A new event is added where you dragged the cursor.
   • To schedule replication for NAS shares or VTL partitions, click the arrow next to the folder to display all shares or partitions. Then click and drag in the row for the share or partition to schedule.
   • The new event must begin after the current time, which is indicated by the dotted vertical line.

   Edit an Existing Event

   • To edit an existing event, double-click the event. If the event is recurring, select Open this occurrence to edit only the one instance of the event, or select Open the series to edit the entire recurring series, and then click OK.
   • You cannot edit an event that occurred in the past.
   • You can also right-click an existing event to see options for editing an event.

2. Define the start and, if applicable, the end of the event.

   • Specify the Start Date and Start Time using the pop-up calendar and drop-down box.
   • (Replication throttle events only) Specify the End Date and End Time. The end date and time must occur after the start date and time.

   Note: For a new event, you can click and drag to adjust the start and end time. For an existing event, you can drag the event to change when it occurs. You can also drag the left or right edge of the event to adjust the start or end time.

3. Enter a brief description of the event in the Description box. (This description will display on the schedule view.)

4. Specify options specific to the type of event. See the following sections:

   • Scheduling a Share or Partition for Replication
   • Scheduling Replication Throttling
   • Scheduling E-mail Reports
   • Scheduling Healthchecks
   • Scheduling Space Reclamation
5. (Required for healthchecks and space reclamation) Specify when and how often the event reoccurs (see Setting Recurrence for a Scheduled Event).
6. Click Apply.
7. Refresh the browser window to make sure the event settings are applied.

Caution: When adding multiple events of the same type, make sure the events do not overlap. If two events of the same type overlap, the later event takes precedence over the earlier event.

Note: After a system reboot, all open-ended events (for example, replication) will restart at their next scheduled time. Events with end times (for example, replication throttle) that are past their start time will have their end action occur.

Configure a replication schedule for a NAS share or VTL partition to automatically replicate the share or partition data to the target system at regular intervals. Disable scheduled replication if you do not want to automatically replicate the share or partition data to the target.

To configure a replication schedule for a share or partition:

1.

On the Scheduler page, add or edit an event in the NAS Replicationor VTL Replication row (see Adding or Editing a Scheduled Event).

2.

In the Share or Partition drop-down box, select the share or partition to schedule for replication.

Only shares or partitions that are enabled for deduplication appear in the drop-down box.

Note: Scheduling a share or partition that has replication disabled will automatically enable replication.

3.

In the Target drop-down box, select the replication target you want to replicate the share or partition to.

4.

Click OK.

5.

(Optional) Specify when and how often the event reoccurs (see Setting Recurrence for a Scheduled Event).

6.

Click Apply.

During replication throttling, the DXi4700 limits the amount of source replication data it sends to not exceed a specified maximum bandwidth. Schedule replication throttling to control the amount of network bandwidth used by source replication at certain times. For example, you might configure replication throttling to occur during planned backup times to avoid network contention.

Note: For more information about configuring the DXi4700 for replication, see About the Replication Page.

To schedule replication throttling:

1.

On the Scheduler page, add or edit an event in the Replication Throttle row (see Adding or Editing a Scheduled Event).

2.

Specify the maximum allowed bandwidth by entering a value in the Bandwidth box and selecting the units in the drop-down box (KB/s or MB/s). The lowest value you can set is 32 KB/s. The highest value you can set is 125 MB/s for 1 GbE and 500 MB/s for 10 GbE.

Caution: Do not set the maximum allowed bandwidth to a value that is lower than necessary. If the maximum allowed bandwidth is set to the lowest value, large replication jobs may fail.

During the replication throttle event, the DXi will limit the amount of data it sends during source replication so that it does not exceed the specified bandwidth. After the replication throttle event ends, the DXi will no longer throttle the sending of source replication data (until the next replication throttle event occurs).

Do not configure a throttle schedule if a constant throttle is enabled (see ). The scheduled replication throttling bandwidth settings take precedence over the constant throttle value. (The currently active replication throttle rate appears on the Home page under Current Activity.)

3.

(Optional) Specify when and how often the event reoccurs (see Setting Recurrence for a Scheduled Event).

4.

Click Apply.

The DXi4700 can automatically generate a report with system status data or with configuration data and send it to all configured e-mail recipients.

Note: To enable the DXi4700 to send e-mail, you must specify an outgoing e-mail server (see Server). In addition, you must specify one or more recipients (see Email ReportsEmail).

To configure a schedule for e-mail reports:

1.

On the Scheduler page, add or edit an event in the Email Reports row (see Adding or Editing a Scheduled Event).

2.

In the Report Type drop-down box, select the type of e-mail report to schedule (Status or Configuration).

3.

(Optional) Specify when and how often the event reoccurs (see Setting Recurrence for a Scheduled Event).

4.

Click Apply.

During healthchecks, the DXi4700 performs tests to verify the health and integrity of the data deduplication blockpool. Schedule healthchecks regularly to make sure the system is healthy and operating correctly. When you schedule healthchecks, only the healthchecks that are currently enabled are run.

Note: For more information about enabling healthchecks, see Healthchecks.

To configure a schedule for healthchecks:

1.

On the Scheduler page, add or edit an event in the Healthchecks row (see Scheduler).

2.

Specify when and how often the event reoccurs (see Scheduler).

Caution: For correct system operation, healthchecks must be run at regular intervals (at least once a week).You can schedule healthchecks to occur daily or weekly but not monthly or yearly. Also, recurrence is required.

3.

Click Apply.

During space reclamation, the DXi4700 deletes unneeded tags from the blockpool to free up disk space. Schedule space reclamation regularly to make sure there is enough disk space to store data.

Caution: Because space reclamation can affect system performance, avoid running space reclamation during known backup periods.

Note: For more information about space reclamation, see Space Reclamation.

To configure a schedule for space reclamation:

1.

On the Scheduler page, add or edit an event in the Space Reclamation row (see Scheduler).

2.

Specify when and how often the event reoccurs (see Scheduler).

Caution: For correct system operation, space reclamation must be run at regular intervals (at least once a week).You can schedule space reclamation to occur daily or weekly but not monthly or yearly. Also, recurrence is required.

3.

Click Apply.

To specify when and how often the event reoccurs:

1.

On the Scheduler page, add or edit an event (see Scheduler).

2.

In the Repeats drop-down box, select Does not repeat to disable recurrence. Or to enable recurrence, select how often the event reoccurs:

Note: Healthchecks and space reclamation must occur at least every seven days or once a week.

Daily	Specify the recurrence interval in days.
Weekly	Specify the recurrence interval in weeks, and select the days the event occurs on.

3.

For recurring events, specify how long the recurrence continues (forever, for a certain number of occurrences, or until a specific date).

Note: For healthchecks and space reclamation, recurrence is always forever.

4.

Click Apply.

To delete an event occurrence or event series.

1.

On the Scheduler page, right-click an event.

2.

On the pop-up menu, select an option:

Delete this occurrence - Remove the selected occurrence in an event series from the schedule.

Delete all occurrences - Remove the entire event series from the schedule.

The event or series is deleted from the schedule and will no longer occur.
