[../images/purgeconfigurations.png] Purge Configurations

    You will see all repository purge configurations and all directory purge configurations.

    *Note:* If you have distributed builds enabled, then repository purging is not currently available on build agents.
    See {{{http://jira.codehaus.org/browse/CONTINUUM-2697} CONTINUUM-2697}} for information.

[../images/repositorypurgeconfiguration-add.png]

* Adding / Editing Directory Purge Configuration

	There are two types of directory purge configuration:
	
	* releases - this will purge the working copies associated with releases.
	
	* buildOutput - this will purge the build output of each project.

* Purging Repository

	* Delete all - will delete the entire contents of the repository
	
	* Days Old - will delete the artifact if it's older than the number of days old but still satisfies the number of retention count. 
	
		Example: 
		
		Days_Old = 30 days   
		
		Retention_Count = 2
		
		If I have 5 artifacts that are older than 30 days, only 3 of them will be deleted because I have to retain any 2 artifacts (Retention count).
		
	* Retention Count - the number of artifacts to retain; all in excess will be deleted
	
	* Delete Released Snapshots - will delete all released snapshots
	
* Purging Directory

	* Delete all
	  
		** Releases Directory - will delete all releases-* directories
	
		** Build Output Directory - will delete all build output of each project
	
	* Days Old - will delete the directory if it's older than the number of days old 
	
	* Retention Count - number of directories to retain

* Steps in purging:
	
	* Perform Delete All purging if it is checked.
	
	* If delete all is not checked, then is days old has a value greater than 0? If it has then perform days old purging.
	
	* If days old is 0 then perform retention count purging.
	
	* Delete released snapshots purging will always be performed if it is checked, unless the Delete All is also checked or it's a directory purging.
