Prune adds a Prune page to Confluence administration. It deletes old page and blog post versions by rule, empties the trash by age, and can do both every day. Only Confluence administrators can open it.

Using Prune

1. Go to Confluence administration (gear icon) and open Prune in the apps section.
2. Overview counts pages, blog posts, old versions and trash items per space and lists the items with most versions. It changes nothing and works without a license.
3. Old versions: set Keep the last N versions, Only versions older than D days, or both, and choose all spaces or some. Press Dry run to see how many versions each page would lose. To delete, press Delete versions and type DELETE. The current version is never deleted.
4. Trash: pick a space, then purge selected items, everything, or items Prune first saw in the trash more than D days ago.
5. Schedule & history: turn on a daily version rule and/or a daily trash rule. The last 30 runs are listed with a CSV report (content ID, space, what was done) that you can copy.

Good to know

• Deleting a version or purging an item is permanent. Confluence has no way to bring it back. Always run a dry run first.
• Confluence renumbers the remaining versions after every delete. Prune re-reads the version list before each single delete, so it always removes the right versions, even on pages edited while a job runs.
• Confluence does not record when an item was moved to the trash. Prune notes the first day it sees each item there (it checks every space once a day) and "older than D days" uses that date. Right after installation every trash item counts as new.
• Long jobs run in the background on Atlassian's platform and continue after interruptions. One job runs at a time; you can stop it.
• Attachments and their versions are not touched.
• When the license is inactive (for example after the trial), Overview and dry runs keep working; deleting, purging and daily rules are off.
