Hybrid Backup Recovery (HBR) is integrated with the Alibaba Cloud snapshot service to provide agentless backup for Elastic Compute Service (ECS) instances and disks. HBR can create crash-consistent snapshots for all disks, including system disks and data disks. You can use the snapshots to back up or restore an entire disk.
Prerequisites
All disks attached to your ECS instances are enhanced SSDs (ESSDs). This ensures crash consistency of the ECS instances. If some disks are not ESSDs, HBR enables the crash consistency feature only for specific disks.Background information
- The ECS instance protection feature allows you to protect ECS instances or specified disks by using a periodic disk backup policy. This ensures low-cost protection.
- You are charged for the usage of ECS snapshots. You are charged a small amount of fees when you use HBR to back up ECS instances. For more information, see Hybrid Backup Recovery (HBR) Pricing.
ECS instance backup is a backup orchestration service that is provided by HBR based on the ECS snapshot capability. The fees for the storage usage of ECS snapshots that are used by this feature are included into the snapshot service bill. If you turn on Replication to Other Region, the fees for the storage usage of ECS snapshots that are replicated to the destination region and the fees for cross-region traffic are also included into the snapshot service bill. For more information, see Snapshots.
Precautions
- You cannot use the ECS instance backup feature to back up or restore local disks. For more information, see Local disks.
If you use local disks to store data, your data may be lost. We recommend that you use the ECS file backup feature to protect your files in local disks and use the database backup feature to protect your databases that are deployed in local disks. For more information, see Back up files from an ECS instance and Database backup.
- You cannot use the ECS instance backup feature to replicate encrypted disks across regions. We recommend that you use the ECS instance backup feature to protect the files in your encrypted disks. For more information, see Back up files from an ECS instance.
- If backup policies are supported in the region where you edit a backup plan, Hybrid Backup Recovery (HBR) automatically converts your backup plan to a backup policy. The parameter settings of your backup plan remain unchanged.
Procedure
- Log on to the HBR console.
- In the left-side navigation pane, choose .
- In the top navigation bar, select a region.
- In the upper-right corner of the page, click Add ECS Backup.
- In the Add ECS Backup panel, configure the backup objects and backup settings. After you create the backup policy, HBR runs the first backup job at the start time that you specified and runs the subsequent backup jobs based on the interval that you specified.
What to do next
The following table describes the tabs that are provided by the ECS instance backup feature. You can efficiently manage backup jobs on these tabs.
Tab | Description | Operation |
---|---|---|
Backed-up ECS Instances | Displays the ECS instances that are protected by HBR. |
|
Job List | Displays the status of each executed job. | You can cancel the jobs that are being executed. |
