The data is internally inconsistent because the server concurrently modifies the data files while they are being copied. The changes done by an uncommitted transaction can be flushed or written to the redo log by the server. So, given a table_id, how do you get the table schema/definition? For that, we have to use undo logs.

Without data backup mechanisms, there can be data loss or system downtime. Even worse, entire operating systems can crash, also resulting in data loss. An incremental backup, which is faster and requires less storage than a full backup, captures changes made since the previous backup. Similarly, accidental deletion is a culprit.

The main reason behind this is that MySQL is a relational database system (RDBMS), and any data that is going to be written in it must respect the RDBMS rules.

Now, the first issue with the logical dump restore approach, as somewhat totally expected though, is with system tables. You cannot load a dump of the MySQL system database from MySQL 8.0 Checking server version. Therefore, you must dump user tables only while getting the system tables from the last backup before the upgrade.
