The commands are also inside the libinstall script inside the repository of aquarium-ctrl.

Backup

Manual backup works as following:

• Before restoring, create the database aquarium on the new device (log in with sudo mysql -u root and execute create database aquarium;)
• Restoring data from backup works with sudo mysql -u root aquarium < name_of_backup.sql
