To send the backups to Google Cloud, navigate to the Store backups in selected destinations section, click on the plus icon, and select S3 Compatible – Google Cloud.

Basic Minimum Settings

To connect to S3 Compatible Custom, you need to specify the following information:

• Access key. In order to get an access/secret key pair to connect your Google Cloud Storage bucket open the Interoperability tab on the Storage Settings page.
• Secret key. In order to get an access/secret key pair to connect your Google Cloud Storage bucket open the Interoperability tab on Storage Settings page.
• Bucket. In order to create or get your Google Cloud Storage bucket open the Browser page of Google Cloud Console.
• Auto delete old backups option

Advanced backup settings

• Auto delete Diff & TranLog after Months. Specify the time period after which old differential and transaction log backups should be deleted.
• Send backup types. Tick off what backup types will be stored in the destination.
• Verify backup files on the destination after uploading. After uploading a file to the destination, SQLBackupAndFTP verifies that the files have been successfully uploaded to the destination. This verification is done using hash sums of the uploaded files.
  This feature is useful as it allows you to understand if there were any issues with the backup at the time of its creation. This option is enabled by default. However, in rare cases, this verification may result in a false positive. This means that the file was uploaded correctly, but for some reason, the file size returned incorrectly. For example, this can happen when the file is saved on a device that supports hardware compression. For such cases, you can disable this option.
• Emergency destination. If this option is enabled, SQLBackupAndFTP will use this destination only when there are errors copying the backup to the primary storage. For example, this might occur if there is insufficient space in the regular storage.

Advanced Google Cloud settings

• Path. Relative path in <storage name>.

Note, S3 on Google Cloud doesn’t support multipart uploading. Use split to volumes option to upload large backup files.
