Operations logging

All operations performed in the Loymax system are accompanied by mandatory logging - recording information about operations and their initiators in separate files. At the same time, the log files do not contain user personal data, passwords, keys and access tokens in open form. At the same time, there is always the opportunity to get the necessary information about the logs (for example, who and when did some action), but access to log files is strictly limited. For example, developers or testers can get excerpts from logs only upon request to the technical support department.

Log files are stored in the Data Storage System with backup technology Raid10. This solution ensure reliable storage of information resources and providing guaranteed access to them. At the moment, the log storage includes records for the entire period of the system.

Database backup

To prevent damage or loss of data stored in the database, the process of their backup has been organised. At the same time, not all data is copied, but only of special value - information about purchases, users, accounts. Copying data for the entire period of operation of the system (full backup) is launched every week, and the changes of the past day (incremental backup) are also copied daily. The backup storage time is 2 weeks from the date of creation. After that, the obsolete files are automatically deleted.

Before updating the system, including making changes to the database, a backup copy of all the databases is created. Only administrators have access to database backup files.

Periodic data cleaning

Historical data are stored in the database for a specified time, after which they are cleared.  The System provides for the following regular cleaning tasks:

• Event calculation;
• Target audience calculation;
• Event data (bonus calculation and deduction, information on purchases, etc.).

Regular clearing tasks for event calculation and target audienc ecalculation are set up in the System by default and perform the clearing on a daily basis. The frequency of regular event data clearing task is configured at setting. The full list of database tables to be cleared by this regular task is presented in the corresponding article.
