Watermark

SmartDR includes a Watermark, or auto delete, system to help manage available disk space. This can be configured from the settings screen under Advanced Options.

The Watermark system will check to see if it needs to run free up space when the software is closed.

When the Watermark system runs, it will do some pre-cleanup first and then check to see if it still needs to free up more space.

• Remove Orphaned Studies This will remove stored images for studies that the system does not have a record of in the database.
• Remove Orphaned Backups Any backup in the default backup location that do not exist in the database will be deleted.
• Clean up Backups Any backup older than 90 days will be deleted.
• Remove Soft Deleted Items When patients and studies are deleted, they are marked as soft deleted in the database. The Watermark will remove all the stored images for soft deleted studies.

Once the pre-cleanup has run, it will then check again if it still is over the high watermark. If it is, it will begin deleting studies. It will start with the oldest studies and work its way up to newer ones. After each study is deleted, the watermark will check to see if it is below the Low Watermark setting. Once the disk usage is below the Low Watermark Setting, the Watermark will stop.

Notification

Every 30 minutes the Watermark system will check the remaining disk space and check it against the High Watermark setting. If disk usage is within 5% of the high watermark setting, a notification will appear in the notification bar. The notification will say:

The system is running low on disk space. Please delete some patients.
