Retention period¶
Goal: you permanently delete projects marked as deleted and old resource pool revisions from the database.
If you delete a project for the first time, it is not actually removed from the database, only marked as deleted. This lets you restore the project later if needed — for example after an accidental deletion. The retention period module lets you permanently delete projects marked for deletion, and old resource pool revisions, from the database.
Prerequisite: in the client properties

on the Retention periods tab, it is defined when projects, project revisions, and resource pool revisions marked for deletion should be permanently deleted.

Step by step¶
Click the Retention period button.

Check the result¶
After clicking Event Log, you can see which data was permanently deleted from the database.

Note
A folder is only permanently deleted once all projects it contains have been permanently deleted after the retention period.
Permanently deleted projects/folders cannot be restored.
Returning to a deleted revision (project/resource pool) is not possible.
Note
You can automate the retention period process by creating a scheduled task under Start > Control Panel > Administration > Task Scheduling.
