Manually Purge Old Data from Database

Tip

To schedule automatic database cleanup, see Automatic Event And Episode Cleanup.

To manually remove old data from the FindFace Security database, use the cleanup utility. You can separately remove the following data:

• matched events and related episodes,
• unmatched events and related episodes,
• full frames of matched events,
• full frames of unmatched events,
• counter records,
• person events.

To invoke the cleanup help message, execute:

sudo findface-security cleanup --help

To entirely remove events and episodes older than a given number of days, use the --events-matched-age/--events-unmatched-age options. For example, to remove unmatched events and episodes older than 5 days, execute:

sudo findface-security cleanup --events-unmatched-age 5

To remove only matched events and episodes older than 5 days, execute:

sudo findface-security cleanup --events-matched-age 5

The following commands remove only full frames of matched/unmatched events:

sudo findface-security cleanup --events-fullframe-matched-age 5
sudo findface-security cleanup --events-fullframe-unmatched-age 5

To remove only counter records, execute:

sudo findface-security cleanup --counter-records-age 5

To remove only person events, execute:

sudo findface-security cleanup --person-events-age 5
