Use Wake-on-LAN
When this setting is enabled, Acronis Backup 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
