Configuring the storage depth of images, vectors and metadata of captured faces enables the automatic archive cleanup. The archive is cleared when one of the conditions that came earlier occurs (see below).

Archive cleanup by remaining free space on the disk

To clear the archive by the remaining free space on the disk, set the size of the required remaining free space on the disk in megabytes in the FaceDBFreeMB registry key. Once the specified value is reached, the old images, vectors and metadata of captured faces will be deleted (see Registry keys reference guide, for details about working with the registry, see Working with Windows OS registry). By default, the size of the remaining free disk space is 1000 megabytes.

Note

Once the specified size is reached, the FaceDB folders will be cleared and the corresponding metadata will be removed from the database. The cleanup is performed on a loop in portions equivalent to 1000 megabytes.

Archive cleanup by retention time

To clear the archive by the retention time, do the following:

  1. Go to the settings panel of the Face recognition server object.

  2. In the Keep archive of recognized faces for (days) field, enter the time period (in days) within which the recognized face images, vectors and metadata should be stored in the database (1). If 0 is specified, then the archive will be cleared every 3 minutes.

    Note

    Once the specified retention time has expired, the FaceDB folders will be cleared and the corresponding metadata will be removed from the database. The cleanup is performed on a loop every day at 00:00.

  3. Click the Apply button to save the changes (2).
