Automate Daily Backups of Settings Tables Records to an Archive Database

Step 1: Before backing up the database, create the applicarearchive schema, execute the applicare-related sql's and ensure all tables are created.

Step 2: Connect to the database via MySQL Workbench, open a new SQL query tab, and execute the following command.

NOTE: Replace the <targetDB> placeholder with actual backup database name before running the query.

NOTE: The query above only backs up data from the settings tables, rather than the entire database.

Step 3: Run the query below to enable the MySQL Event Scheduler and schedule the sp_BatchArchiveYesterday procedure to run daily at 1:00 AM.

SET GLOBAL event_scheduler = ON;
DELIMITER //
DROP EVENT IF EXISTS applicarearchive.setting_table_daily_archive_at_1am; //
CREATE EVENT applicarearchive.setting_table_daily_archive_at_1am
ON SCHEDULE EVERY 1 DAY
STARTS (CURRENT_DATE + INTERVAL 1 DAY + INTERVAL 1 HOUR)
DO
  BEGIN
    TRUNCATE TABLE applicarearchive.archive_log;
    CALL applicarearchive.sp_MasterArchive_Settings();
  END //

DELIMITER ;

To modify the scheduled time, first execute the query below to drop the existing event, then re-create it with your desired schedule.

DROP EVENT IF EXISTS applicarearchivesettings.daily_archive_at_1am;

To change the time to 8:00 PM, We need to adjust the INTERVAL in the STARTS clause. Since MySQL uses a 24-hour format, 8:00 PM is 20 hours.

E.g.

SET GLOBAL event_scheduler = ON;
DELIMITER //
DROP EVENT IF EXISTS applicarearchive.setting_table_daily_archive_at_8pm //
CREATE EVENT applicarearchive.setting_table_daily_archive_at_8pm
ON SCHEDULE EVERY 1 DAY
STARTS (CURRENT_DATE + INTERVAL 1 DAY + INTERVAL 20 HOUR)
DO
  BEGIN
    TRUNCATE TABLE applicarearchive.archive_log;
    CALL applicarearchive.sp_MasterArchive_Settings();
  END //

DELIMITER ;

NOTE: Execute the below query to confirm the event is saved in the system.

SHOW EVENTS FROM applicarearchive;

Step 4: We need to create the archive_log table in your archive database. This table will record which table was processed, how many rows were moved, and exactly when it finished.

CREATE TABLE IF NOT EXISTS applicarearchive.archive_log (
    id INT AUTO_INCREMENT PRIMARY KEY,
    table_name VARCHAR(255),
    rows_moved INT,
    finish_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    status VARCHAR(255)
);

Explanation of the Columns:

• id: A unique number for every entry.

• table_name: Records the table name (and the column name used, e.g., oshistory_detail [dt]).

• rows_moved: The number of records successfully transferred for "Yesterday".

• finish_time: The exact date and time the backup for that specific table completed.

• status: The status column is your best friend. If a table fails because of a schema change (like a missing column in the archive), you will see "FAIL: Could not find matching table/columns" immediately.

Step 5: Execute query to see the results. It will show you the most recent backups at the top.

SELECT * FROM applicarearchive.archive_log ORDER BY finish_time DESC;
