To use Google Cloud Storage as a backup destination, you must have a Google Storage account. If you don't already have a Google Storage account, you can visit their website in order to create one.
To create a Google Storage backup destination within SQL Backup Master, click the Add toolbar button in the Destinations section of the Database Backup Editor window. When prompted to choose a destination, select Google Storage and click the Select button.
The Google Storage backup destination service address can be overridden, allowing it to be used with arbitrary S3 compatible service endpoints.
For more information, see the S3 Compatible Overview help topic.
Please see the Amazon S3 help topic for discussion of the remaining configuration options.
