This section describes how to set the time that the scheduled backup of the Lucene indexes occurs.
- 
        Copy the following file:
        <configRoot>/classes/alfresco/scheduled-jobs-context.xml 
- Locate the <extension> directory, and paste the copied file into this location.
- 
        Rename the file to custom-scheduled-jobs-context.xml.
        As your override file ends with -context.xml, you do not need to point to your file. 
- 
        Delete each pair of <bean> </bean> tags (excluding the
          pair containing the indexBackupTrigger bean).
        This bean contains the following properties: <!-- trigger at 3am each day --> <property name="cronExpression"> <value>0 0 3 * * ?</value> </property>The default is to run the job at 3am every day. 
- 
        Modify the cronExpression values, if required
        The value 0 0 3 * * ? specifies the backup is triggered at 3am every day. After each backup scheduled in the indexBackupTrigger bean, perform your normal backup of this directory. Note: Each backup will overwrite the existing backup.
