5.4. Conditions

Conditions add more flexibility to the scheduler, enabling to execute backup tasks with respect to

certain conditions. Once a specified event occurs (see the Scheduling section for the list of available

events), the scheduler checks the specified condition and executes the task if the condition is met.

The scheduler behavior in case the event occurs but the condition (or any of multiple conditions) is

not met, is defined by the Task start conditions (p. 60) backup option. There, you can specify how

important the conditions are for the backup strategy:

• conditions are obligatory - put the backup task run on hold until all the conditions are met.

• conditions are preferable, but a backup task run has higher priority - put the task on hold for the

specified time interval. If the time interval lapses and the conditions are still not met, run the task

anyway. With this setting, the program will automatically handle the situation when the

conditions are not met for too long and further delaying the backup is undesirable.

• backup task start time matters - skip the backup task if the conditions are not met at the time

when the task should be started. Skipping the task run makes sense when you need to back up

data strictly at the specified time, especially if the events are relatively often.

Adding multiple conditions

Multiple conditions must be met simultaneously to enable task execution.

5.4.1. Location's host is available

Applies to: Windows, Linux

"Location's host is available" means that the machine hosting the destination for storing archives on a

networked drive is available.

Example:

Backing up data to the networked location is performed on workdays at 9:00 PM. If the location's

host is not available at that moment (for instance, due to maintenance work), skip the backup and

wait for the next workday to start the task. It is assumed that the backup task should not be started

at all rather than failed.

• Event: Weekly, Every 1 week(s) on <workdays>; Once at 09:00:00 PM.

• Condition: Location's host is available

• Task start conditions: Skip the task execution.

As a result,

(1) If 9:00 PM comes and the location's host is available, the backup task starts right on time.

(2) If 9:00 PM comes but the host is unavailable at the moment, the backup task will start on the next

workday if the location's host is available.

(3) If the location's host will never be available on workdays at 9:00 PM, the task never starts.
