- invent a time machine
- return to a date 90 days ago
- enable logging of all requests or set up the maintenance and continuous archiving of a binary log
- return to the present and analyze the log configured in the last step
If you have not configured to log changes, then no one will store it . Even the mvcc versioner of innodb will try to clean up old versions of strings. Because why store a bunch of data if there was no requirement to store it?
