When creating backup from ARCHIVE table with mysqldump, it is not possible to restore this dump file, because error: Can't write; duplicate key in table 't1'
Mysqldump creates dump with CREATE TABLE ... AUTO_INCREMENT=next_id value and after CREATE TABLE it is not possible to insert data with lower id-s.
MariaDB [test]> CREATE TABLE t1(id INT AUTO_INCREMENT, PRIMARY KEY (`id`)) ENGINE=ARCHIVE;
