Regular Tasks

By default, eRAD PACS manages the disk usage automatically, but never removes primary image data, report data or orders unless the administrator explicitly instructs it to do so. Even then, eRAD PACS only does so when it needs additional disk space. This means no purging occurs until the Free Space Limit (see: Disk Limit) is reached, even if a study is older than the specified purge period. All purging will be processed during off-peak hours, usually in the early morning. Therefore, after changes to the settings are made, eRAD PACS must run the purging process before the settings take effect. Stopping and restarting the server will not start the purge process.

To set the purge rules:

1. Go to Admin/Server Settings
2. Select Regular Tasks

Only users with support rights can edit these settings.

There are two options:

• Purge New Studies After - maximum number of days a study will exist on the server
• Keep New Studies For - number of days a study must exist on the server before it can become eligible for purging
