MySQL / MariaDB : alle DBs schnell exportieren

Mysql export kann sehr lange dauert, wenn man viele und große Datenbanken hat. Damit man schnell ein Backup von allen DBs erstellen kann:

mysqldump --opt --quick --all-databases > /root/backup/mysql/alldbs.sql
  
  

Wenn User login notwendig ist :

mysqldump -u root -p --opt --quick --all-databases > /root/backup/mysql/alldbs.sql

 

  • --opt steht für:
    •  --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset.
      •   --quick spart viel Zeit, wenn es um sehr große Datenbanken/Tabellen geht.

    Drupal Upgrade (Drupal 9 » Drupal 10)

    I had this exact issue and your site was the only place I found the fix.

    It'd be nice if the module developer applied your fix though.

    Good work! Much appreciated!
