Huawei Cloud ECS Instance Full Restore
To restore one or a group of ECS Instances, please go to Cloud Backup > Restore > Full Restore page to create a full ECS instance restore job. Please follow the below steps to create the job.
Step 1. Select Restore Point
In the Restore Point dropdown list, select a backup node which stores the desired restore points.
Select a target ECS Instance restore point under the Huawei cloud platform which you want to restore. You can quickly find the target restore point by searching the job name, Instance name or the date of the restore point in the search box.
You can restore a group of Instances by selecting one of the restore points under each of the Instances. After selecting the desired restore point under instance which you want to recover, click Next to continue.
Step 2. Select Restore Destination
In the Select cloud platform dropdown list, select a target cloud platform which you wish to run the restored Instances. In the Select recovery type dropdown list, select a recovery type on which you want to restore. The Instance Recovery will restore the whole instance and create a new instance when restore. The Volume Recovery will restore some or all of the instance's volumes.
When done selecting the restore destination and type, users can directly click on Options button to continue. The Volume Name can be modified, default is the original instance name and timepoint format. Users need to configure the Region and Availability Zone, the volumes of the same instance in the same job must be restored to the same region and the same availability zone. If multiple volumes of an instance need to be restored to different regions, multiple jobs can be created to restore them separately. Configure the KMS key, the default is the same as the original volume configuration. Then click OK button to confirm the settings.
Step 3. Configure Restore Strategy
For the job schedule, you can configure the ECS instance restore job as once-off restore or scheduled Recovery.
If you choose Once-off Restore, the restore job will start running right after the job has been created. If you choose Restore As Scheduled, you need to set restore schedules. After this, the job will run as scheduled.
Notice
A "once-off" restore job will run only once and will only restore the selected Instance(s) for one time, after that the job will be moved into history job list as a history record. But a "restore as scheduled" restore job will run and restore the selected Instance(s) regularly according to the time schedules, so, users should be aware of that, a "restore as scheduled" job could cause a lot of duplicated data!
For Throttling Policy and Advanced Strategy, these settings are optional, throttling policy works the same principle as for backup jobs. For advanced strategy, due to the unique architecture of public cloud platforms, the transfer threads will be setup with 1 as default for the ECS instance restore job.
For Transmission Strategy of a Huawei Cloud ECS instance restore job, users can choose among different Proxy Instance Type for Huawei Cloud. Transfer Agent Bind Public IP is used to if there is a prepaid public IP, users can specify that the agent use this IP to reduce costs associated with large data tansfers. If the specified IP is unavailable, a separate one will be created. Payment Methods includes Pricing by Bandwidth and Pricing by Traffic, users can select the corresponding method according to thier needs.
For Advanced Strategy, if there is a snapshot in the recovery destination area (same as the availability area) at the selected timepoint, it will restore from the snapshot. If the snapshot is not detected, it will be downgraded to backup data recovery.
Step 4. Review and Confirm Job Settings
After finishing the above settings, you are able to review and confirm all settings here. Click on Submit to confirm creating this job. When the job is created, you will be redirected to the Monitor Center > Jobs page. If this ECS instance restore job is configured as Once-off Restore, it will start restoring the instance(s) right after the creation of this job.
