Hi Hideki Masu,
Thanks for working on MySQL customer.
From MySQL 6.x.x have the online backup with storage engine co-ordination. Normally we recommend the MySQL enterprise release for the Our customers.The latest enterprise version is 5.1.43,
Please do consider the following for Snapcreator with MySQL module
1. Is the database spread across more than on volume
2. Is the MySQL do require DR solution
3. How frequent the backup schedule
4. Is the customer require client and server module for the backup
5. The database size doesn't matter for snapcreator, any way you can get that details.
As keith suggest, to maintain the consistency we are using read only mode, take the snapshot and release the lock. To Keep the datas in consistency during backup
For Snapcreator the type of storage engine is doesn't mater.
snapcreator for MySQL works very well now.
Rgds,
