You can back up and restore configuration and service data by using the Microsoft Azure Stack Hub Infrastructure Backup Service. Each Azure Stack Hub installation contains an instance of the service. You can use backups that the service creates for the redeployment of the Azure Stack Hub cloud to restore identity, security, and Azure Resource Manager data.
Infrastructure Backup Service includes the following features:
- Backup infrastructure services—Coordinates backup across a subset of infrastructure services in Azure Stack Hub. If there is a disaster, the data can be restored as part of a redeployment.
- Compression and encryption of exported backup data—Backup data is compressed and encrypted by the system before it is exported to the external storage location that the administrator provides.
- Backup job monitoring—System notifies when backup jobs fail and provides remediation steps.
- Backup management experience—The backup Resource Provider supports enabling backup.
- Cloud recovery—If there is a catastrophic data loss, you can use backups to restore core Azure Stack Hub information as part of the deployment.
Note: Infrastructure Backup Service does not include user data and applications. For instructions about backing up and restoring App Services, SQL, and MySQL resource providers and associated user data, see the following sections.
For more information about the Azure Stack Hub Infrastructure Backup Service, see Recover data in Azure Stack Hub with the Infrastructure Backup Service on the Microsoft website.
You can enable a backup when you are ready to put your cloud into production. Do not enable backup if you plan to do testing and validation for a long time.
Before you enable the backup service, ensure that you have all the backup requirements in place. For details, see Backup requirements.
Verify the backup requirements for the Azure Stack Hub Infrastructure Backup Service:
- Storage location—You need a file share accessible from Azure Stack Hub that can contain seven backups. Each backup is about 10 GB. Your share should be able to store 140 GB of backups.
- Credentials—You need a domain user account and credentials, for example, you may use the Azure Stack Hub administrator credentials.
- Encryption key—Backup files are encrypted using this key. Make sure to store this key in a secure location. Once you set this key for the first time or rotate the key in the future, you cannot view this key from this interface.
