Cloud metadata is generated by a cloud block management system on a first storage array. The cloud metadata includes information identifying one or more cloud providers, one or more cloud repositories created on the cloud providers, and block objects stored in the cloud repositories. A metadata backup file containing a copy of the cloud metadata is generated, encrypted, and exported to an external computer. A second cloud block management system is created on a second storage array, and the metadata backup file containing the copy of the cloud metadata is decrypted and imported to the second cloud block management system. The cloud metadata from the metadata backup file is used to configure the second cloud block management system to access the one or more cloud providers, access the one or more cloud repositories created on the cloud providers, and to access the block objects stored in the cloud repositories.
