By default, Confluence runs its daily backup at 2.00 AM. You can configure Confluence to perform the backup at a time that is best suited to you or your organisational needs.
 | Time is derived from the Confluence server
The time zone is taken from the server on which Confluence is running. To check the time according to the server, do the following:
Go to the 'Administration Console' view. To do this:
- Go to a page in the space and choose 'Administration' from the 'User' menu, which is labelled with your Confluence username. The 'Administration Console' view will open.
- Click 'System Information' in the left-hand panel and look at the 'System Time'.

Confluence uses Quartz for scheduling periodic jobs. To change the time of your daily backup, you will need to edit the Quartz configuration.
To change the time of your daily backup
- Open the Quartz configuration file schedulingSubsystemContext.xml located under confluence/WEB-INF/lib/confluence-2.6.0.jar
- Find the following section of the file:
<bean id="backupTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="backupJob"/>
</property>
<property name="cronExpression">
<value>0 0 2 * * ?</value>
</property>
</bean>
- The string '0 0 2 * * ?' sets up a Cron Trigger for the job to run at the zeroth second of the zeroth minute of the 2nd hour, every day of every month, every day of the week.
- Re-jar the file, either with a zip utility (change the title of .zip back to .jar) or a java command.
- You can set a new time by editing this string. Note that the date and time format in this configuration file is in this order:
Second minute hour day
- Restart Confluence.
For example, to set the new time to twenty past ten PM, change the string to '0 20 22 * * ?'.
If you wanted to back up only once a week, for example, at midnight on Sundays, you would change the string to '0 0 0 ? * SUN'.
