What is the Plesk Daily Maintenance script?

Question

• What are the Plesk Daily Maintenance tasks used for?

Note: Daily email notifications related to the execution of this script are sent to server administrator periodically and they always mention one of the following files:

Windows Server OS: %plesk_dir%\admin\plib\DailyMaintainance\script.php

Debian-based Linux OS: /opt/psa/admin/plib/DailyMaintainance/script.php

RHEL-based Linux OS: /usr/local/psa/admin/plib/DailyMaintainance/script.php

Answer

The Plesk Daily Maintenance script is a script that launches Plesk Daily Maintenance tasks (once per day).

The tasks that are performed when this script is launched are tied to various very important maintenance-related operations within Plesk, such as:

• Checking for Plesk updates
• Installing updates
• Updating license keys
• Calculating Statistics
• Updating application catalog cache
• Log rotation

The mentioned operations can also be launched separately. See the following articles for details:
