The administration console allows you to schedule various administrative jobs in Confluence, so that they are executed at regular time intervals. The types of jobs which can be scheduled cover:
- Confluence site backups
- Storage optimization jobs to clear Confluence's temporary files and caches
- Index optimization jobs to ensure Confluence's search index is up to date
- Mail queue optimization jobs to ensure Confluence's mail queue is maintained and notifications have been sent.
You'll need System Administrator permissions in order to edit and manually run jobs.

- Next Execution -the date and time when the job is next scheduled to be executed. This field will contain dash symbol ('-') if the job is disabled.
- Avg. Duration - the length of time (in milliseconds) that it took to complete the job (the last time it ran).
- Actions - Options to edit the job's schedule, run it manually, view the history or disable the job.

|Versions Removal (Hard)||Deletes any historical page or attachment versions that don't meet the retention rules in one go, rather than in batches. This job can be run manually when required, but may have an impact on your site performance.||Per cluster||Disabled by default|
A cron expression is a string of 6-7 'time interval' fields that defines the frequency with which a job is executed. Each of these fields can be expressed as either a numerical value or a special character and each field is separated by at least one space or tab character.
The table below is shows the order of time interval fields in a cron expression and each field's permitted numerical values.
You can specify a special character instead of a numerical value for any field in the cron expression to provide flexibility in defining a job's frequency. Common special characters include:
- '*' — a 'wild card' that indicates 'all permitted values'.
- '?' — indicates 'ignore this time interval' in the cron expression. That is, the cron expression will not be bound by the time interval (such as 'Month', 'Day of week' or 'Year') to which this character is specified.
For more information about cron expressions, please refer to the Cron Trigger tutorial on the Quartz website.
