You can call the DescribeCrossRegionBackups operation to query the cross-region data backup files of an ApsaraDB for RDS instance.

For more information about how to query the cross-region log backup files of an RDS instance, see DescribeCrossRegionLogBackupFiles.

Before you call this operation, make sure that the instance runs one of the following database engine versions and RDS editions:

  • MySQL 8.0 on RDS High-availability Edition (with local SSDs)
  • MySQL 5.7 on RDS High-availability Edition (with local SSDs)
  • MySQL 5.6

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
