I need professional MariaDB technical support, an expert who deals with administrative matters at a high level. I inherited the MariaDB project and database from my colleague at work. It was upgraded last year from version 10.5 to 11.1 and finally to 11.2 - on Windows 2019 server. It turns out that the database folder was left in the 10.5 folder and we are running on version 11.2 And this application worked until January 11. After restarting the server, it turned out that the latest files in the data/database folder were from December 17, and now my suspicion is that newer records and modifications of things are in two MariaDB log files, they are huge, 100MB each. they are in the Include folder: e.g. ib_logfile101 so there is hope that all the records are still available there. The task is as follows: reinstall MariaDB, use the database files from December 17, and download from the logs until January 11, so that the database is consistent and there is almost no data loss. It looks like we have everything we need

With extensive skills in database administration, I offer the expertise you need to swiftly resolve your MariaDB issue. Having worked on various high-level administrative tasks, such as data migration and system upgrading, similar to your situation, I am familiar with troubleshooting and fixing complex database problems. Even more, I bring an added advantage of my comprehensive understanding of server infrastructure design and support that would be crucial in your task at hand. To ensure minimal data loss and consistency in the database, I propose a thorough yet agile approach. Firstly, I'd expertly reinstall MariaDB using the appropriate database files from December 17th while preserving any unsaved records trapped in the over-sized log files. By intelligently 'reading' these logs, we can extract vital information from the period between December 17th - January 11th and merge them into the newly reinstalled database. As a professional who values data integrity deeply, I guarantee meticulous attention through this process and commit to delivering a consistent MariaDB system at the end. My wealth of experience working with major cloud platforms (Amazon AWS, Google Cloud, Microsoft Azure) also positions me well to understand any further needs for migration or implementation you may have for your project. I eagerly await the opportunity to support you!
