Hybrid Backup Recovery (HBR) is a fully-managed online backup service that allows you to back up data to the cloud in a convenient, efficient, and secure manner. You can use HBR to back up data to a cloud vault from Elastic Computing Service (ECS) instances, ECS databases, ECS files, Apsara File Storage NAS file systems, NAS clusters, Object Storage Service (OSS) buckets, and self-managed data centers that store files, databases, virtual machines (VMs), and large scale NAS file systems. You can also implement disaster recovery and archive data based on the archive policies that you configure for the preceding resources.
- Back up data to the cloud
You can efficiently back up important data to a backup vault by using an internal network. Backup data sources include ECS files, self-managed MySQL, Oracle, SQL Server, and SAP HANA databases, NAS file systems, and OSS buckets. You can perform real-time backups of MySQL and Oracle databases with a near-zero recovery point objective (RPO) in real time. In addition, you can back up data from other cloud platforms to a backup vault on Alibaba Cloud.
- Back up on-premises data to the cloud
You can back up on-premises data from servers, NAS file systems, VMware VMs, and databases to a backup vault on the cloud. You can configure backup policies based on your business requirements.
- Backup and disaster recovery of ECS instances across regions
- HBR provides mirror vaults for you to back up data across regions. This enhances data security.
- HBR supports high-performance cross-region disaster recovery with recovery point objective (RPO) in seconds and recovery time objective (RTO) in minutes.
- Migrate VMware VMs to the cloud
HBR allows you to migrate on-premises VMware VMs to the cloud in an agentless manner. You can also use HBR to perform incremental migration with ease.
- Archive files from on-premises NAS file systems to the cloud
HBR allows you to archive a large number of files from your on-premises NAS file systems to an archive vault on the cloud. You can customize an archive policy. You can also search on-premises storage space and archive libraries for files in a full-text manner within seconds.
The following table describes the terms that are used in HBR.
|Backup source||The host on which the data that you want to back up is stored, such as a server, a virtual machine, or an ECS instance.|
|Client||The client that you install on a backup source to back up and restore data. You must
install an appropriate client for different backup sources.
Each client supports timed retry to guarantee backup stability. This way, data can be backed up even when temporary network jitter occurs.
|Region||The physical location of an Alibaba Cloud data center. After a resource is created, you cannot change the region of the resource. For more information, see Supported regions.|
|Backup vault||The HBR cloud repository that is used to store backup data in the cloud. You can back
up data from multiple clients to the same vault. This helps you manage the backup
data and reduce management time and costs.
Each backup vault supports an unlimited number of clients and storage capacity with data reliability of 99.9999999999% (twelve 9s). You can install a client and extend the storage capacity based on your business requirements.
You must specify an appropriate region for each backup vault to improve backup performance and facilitate disaster recovery. After a backup vault is created, you cannot change the region of the backup vault. A backup vault is also the basic unit that you can use to remove duplicates or compress data.
