 | <a name="input_backup_encryption_key_crn"></a> [backup\_encryption\_key\_crn](#input\_backup\_encryption\_key\_crn) | The CRN of a Key Protect key that you want to use for encrypting the disk that holds deployment backups. Only used if var.kms\_encryption\_enabled is set to true. BYOK for backups is available only in US regions us-south and us-east, and in eu-de. Only keys in the us-south and eu-de are durable to region failures. To ensure that your backups are available even if a region failure occurs, use a key from us-south or eu-de. Hyper Protect Crypto Services for IBM Cloud Databases backups is not currently supported. If no value is passed here, the value passed for the 'kms\_key\_crn' variable is used, unless 'use\_default\_backup\_encryption\_key' is set to 'true'. And if a HPCS value is passed for var.kms\_key\_crn, the database backup encryption uses the default encryption keys. | `string` | `null` | no |
