Scheduler

The Scheduler page allows you to manage scheduled events on the InfiniGuard DDE, including replication and replication throttling. With schedules, you specify when certain events should occur, and the system automatically performs those events at the specified time. Events can be one-time only, or they can reoccur at defined intervals

To access the Scheduler page, click the Configuration menu, and then click the Scheduler tab.

Scheduler Page


Tasks

Use the Scheduler page to perform the following tasks:


Viewing Scheduled Events

The Scheduler page displays all replication and replication throttle 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.

Tasks

Use the following toolbar controls to adjust the schedule view:

  • To show or hide all shares or partitions, click the plus [ + ] or minus [ - ] icons.
  • To filter shares or partitions based on name, begin typing in the Filter box. Click the x to clear the filter.
  • To view the schedule for a specific day, select it in the Goto pop-up calendar.
  • To view the schedule for today, click Now.
  • To update the schedule view with the latest data, click the Refresh icon.
  • To move the view backward or forward in time, click the arrows.
  • To change the number of days displayed at a time, click Daily, Weekly, or Monthly.


Note

The thickness of the bars on the schedule view varies based on the type of event and the selected time frame. All other open-ended events have a default span of 2 hours.

Adding or Editing a Scheduled Event

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:

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.


Adding a New Event
page

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:

5. 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.

Scheduling a Share or Partition for Replication

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.

Note

To schedule a share or partition for replication, you must first add one or more replication targets (see Replication Configuration). In addition, you must add one or more shares or partitions with deduplication enabled and at least one target selected (see NAS Summary or Partitions).


Note

Disabling replication for a share or partition, or deleting a share or partition, does not delete any scheduled replication events for that share or partition. If you no longer want to schedule the share or partition for replication, manually delete the schedule (see Deleting a Scheduled Event)

To configure a replication schedule for a share or partition:

1. On the Scheduler page, add or edit an event in the NAS Replication or 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.

Scheduling Replication Throttling

During replication throttling, the InfiniGuard DDE 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 InfiniGuard for replication, (see Replication.)

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.

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

4. Click Apply.

About Replication Throttling Statistics

Keep in mind the following information when observing actual network bandwidth usage during a replication throttle event:

  • During a replication throttle event, only outgoing replication data traffic is throttled, not other outgoing traffic. Because of this, you may observe network usage to be higher than the specified maximum bandwidth. Differences in the sampling time period may also cause discrepancies between the specified maximum bandwidth and observed traffic.
  • If the InfiniGuard DDE is configured to use a bonded network interface for replication traffic, load balancing is determined independently by the bonding mode selected for the interface (see Network). Because of this, you may need to sum the values for all slave devices in the bonded interface to calculate the overall outgoing traffic rate.

    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 InfiniGuard DDE 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 DDE 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. 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.)
  • The replication throttle bandwidth maximum is specified in KB/s or MB/s, so depending on the statistic or report you are observing, you may need to convert the bandwidth maximum to Kb/s or Mb/s in order to correctly compare it to the observed values.


Setting Recurrence for a Scheduled Event

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:

    • 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).

4. Click Apply.

Deleting a Scheduled Event

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.
