Introduction

In MySQL there is a tool called mysqldump available. To get a consistent backup you need to use the InnoDB storage engine and specify the mysqldump option --single-transaction. The backups generated by mysqldump contain the complete SQL code to recreate the YAWL database.

Backup

For example a full backup of all databases with MySQL is get by:

mysqldump --all-databases --single-transaction > yawlDatabase.sql

To backup only your YAWL database, you can specify the name (usually "yawl") by:

mysqldump --databases yaug --single-transaction > yawlDatabase.sql

Restore

To restore the YAWL database please first shutdown all running YAWL services. Then issue the following command:

mysql < yawlDatabase.sql

You may also supply username and password of a database user.
