eRAD PACS manages the disk usage automatically, but will never remove primary image data, report data or orders unless the administrator instructs it to do so. Even then, this is only done when additional disk space is needed. No purging occurs until the free space limit is reached, even if a study is older than the specified purge period. All purging is processed during off-peak hours, usually in the early morning. Therefore, after you change these settings, you must wait until server runs the purging process before the settings take affect. Stopping and restarting the server will not start the purge process.
To set the purge rules, go to the Settings page, and scroll down to the Regular Tasks section. The options are:
Purge Regular Studies: number of days that must expire before a study becomes eligible for purging.
Purge Preliminary/Final Studies: number of days that must expire before a study in the Preliminary or Final state becomes eligible for purging.
Purge Orders: number of days that an expired order will remain in the work list.
Keep New Studies: number of days new studies must reside on the server before being eligible for removal.
