Advanced scheduling settings

The following advanced settings are available when setting up a daily, weekly, or monthly schedule in a centralized backup plan.

Use Wake-on-LAN

When this setting is enabled, Acronis Backup & Recovery 11.5 Management Server will use the Wake-on-LAN functionality to wake up turned-off registered machines when a backup, cleanup or validation is scheduled to start. If the backup task on each machine starts with a delay (see the next setting), the management server will wake up the machines according to those delays.

Before using this setting, make sure that you have enabled Wake-on-LAN on the registered machines. The machine's basic input/output system (BIOS) configuration, network adapter configuration, and the operating system configuration must allow waking up the machine from the powered-off state, also known as the S5 or G2 power state.

Distribute start time within the time window

When this setting is enabled, the backup task on each registered machine will start with a specific delay from the start time set in the backup plan. This distributes the tasks' actual start times within a time interval.

You may want to use this setting when creating a centralized backup plan for backing up multiple machines to a network location, to avoid excessive network load.

The delay values range from zero to the specified maximum delay value, and are determined according to the chosen distribution method. The delay value for each machine is determined when the backup plan is deployed to the machine, and remains the same until you edit the backup plan and change the maximum delay value.

The conditions, if any, will be checked at the task's actual start time on each machine.

Regardless of the maximum delay value, all start times stay within the same date. For example, if your backup plan starts at 23:00 and the maximum delay value is two hours, the start times of all tasks will lie between 23:00 and 23:59 only. The tasks may finish after midnight, as usual.

The following examples illustrate this setting.

Example 1

Suppose that you are deploying a centralized backup plan with the following schedule to three machines:

Run the task: Daily
Once at: 09:00:00 AM

Distribute start time within the time window
Maximum delay: 1 Hour(s)
Distribution method: Random

In this case, the task's start time on each machine may be any time between 09:00:00 AM and 09:59:59 AM. For instance:

First machine: Every day at 09:30:03 AM

Second machine: Every day at 09:00:00 AM

Third machine: Every day at 09:59:59 AM

Example 2

Suppose that you are deploying a centralized backup plan with the following schedule to three machines:

Run the task: Daily
Every: 2 Hour(s) From: 09:00:00 AM Until: 11:00:00 AM

Distribute start time within the time window
Maximum delay: 1 Hour(s)
Distribution method: Random

In this case, the time of the task's first run on each machine may be any time between 09:00:00 AM and 09:59:59 AM; the interval between the first and the second run is exactly two hours. For instance:

First machine: Every day at 09:30:03 AM and at 11:30:03 AM

Second machine: Every day at 09:00:00 AM and at 11:00:00 AM

Third machine: Every day at 09:59:59 AM and at 11:59:59 AM

To specify advanced settings

  1. Connect to the management server and then start creating a backup plan.
  2. In How to back up, select the Simple, GFS (Grandfather-Father-Son), Tower of Hanoi, or Custom backup scheme.
  3. Depending on the backup scheme, do one of the following:
    1. Click Schedule to specify a schedule for the scheme.
    2. Under Run the task, select Daily, Weekly, or Monthly.
    3. In the Advanced settings area, click Change.
  4. To enable the use of the Wake-on-LAN functionality, select the Use Wake-on-LAN check box.
  5. To distribute the centralized backup tasks' start times, select the Distribute start time within the time window check box and then specify the maximum delay value and the distribution method.
