Prerequisites
ECS files are backed up. Historical recovery points are available. For more information, see Back up files from an ECS instance.
The destination for data restoration is prepared.
The destination can be the source ECS instance, a new ECS instance, or an on-premises server.
If you restore files to a new ECS instance, a Cloud Backup client must be installed on the ECS instance and the Client Status must be Activated on the ECS File Backup page in the console. Cloud Backup can automatically install a backup client on ECS instances.
If you restore files to an on-premises server, a Cloud Backup client must be installed on the on-premises server and the Client Status must be Activated on the On-Premises File Backup page in the console. You can install a Cloud Backup client for Linux or Windows on an on-premises server. For more information, see Download and activate a Cloud Backup client for Windows and Download and activate a Cloud Backup client for Linux.
Usage notes
When you restore ECS files, you cannot restore socket files or hard links.
Billing
You are not charged for the restore feature.
Important
When you restore files to a new ECS instance, you must install a Cloud Backup client on the new ECS instance. In this case, a client usage fee is incurred.
When you restore files to an on-premises server, you must install a Cloud Backup client on the on-premises server. In this case, a client usage fee and an outbound traffic fee are incurred.
For more information, see Billing methods and billable items.
Create a restore job
Log on to the Cloud Backup console.
In the left-side navigation pane, choose .
In the top navigation bar, select a region.
On the Backup Plans tab, click the 
icon to the left of the ECS instance that is backed up.
Click an available historical backup point and then click Restore.
Note
We recommend that you select an appropriate historical backup point. The backup data varies at different backup points.
In the Create Restore Job panel, perform the following steps.
In the Select Restore Items step, configure the Restore Items parameter and click Next.
The following table describes the valid values of the parameter.
Parameter | Description |
Restore Items | The files or folders that you want to restore. Include All Files: All files on the client are restored. Include Files: Select the files or folders that you want to restore. You can also click Enter Paths to specify the files that you want to restore. In the text box, enter the paths to the files or folders that you want to restore. Cloud Backup restores files on the client based on the specified restore policy. In the text box, enter one path in each line and make sure that the first folder in each path is the lowest-level folder in the directory that is backed up. For example, if the files in folder/test/data are backed up, and you want to restore the file.txt and abc.png files in the data folder, specify the following paths:
/data/file.txt
/data/abc.png
Exclude Files: Select the files or folders that you do not want to restore. Cloud Backup restores all files and folders that are not selected. You can also click Enter Paths to specify the files that you want to restore. In the text box, enter the paths to the files or folders that you want to restore. Cloud Backup restores files on the client based on the specified restore policy. In the text box, enter one path in each line and make sure that the first folder in each path is the lowest-level folder in the directory that is backed up. For example, if the files in folder/test/data are backed up, and you want to restore the file.txt and abc.png files in the data folder, specify the following paths:
/data/file.txt
/data/abc.png
|
In the Restore Destination step, specify a destination for data restoration and click Next.
Parameter | Description |
Destination Type | Select the type of the client. Backup Clients for ECS (New): Select this option when you restore files to the source ECS instance or a new ECS instance. On-premises Client (New): Select this option when you restore files to an on-premises server.
|
Backup Client Name/ID | Select the name of the client. |
In the Destination Path step, specify the recovery path and click Start to Restore.
Parameter | Description |
Restore Path Type | |
Destination Path | This parameter is required only if you set the Restore Path Type parameter to Specify Path. This parameter specifies the path to which the files are restored. |
File Conflict Policy | |
Virus Detection During Restoration | If you turn on this switch, Cloud Backup performs virus detection on all files to be restored during restoration. The console provides the detailed information about this feature. For more information, see Backup point virus detection. |
When Recovery Items Contain Detected Viruses | |
After the restore job is created, you can view the progress of the restore job in the Status column on the Restore Jobs tab.
After the restoration progress changes to Completed (100%), you can log on to the destination ECS instance or on-premises server to view the restored ECS files.
Troubleshooting
If the Status of the restore job is abnormal, you can resolve the issue based on the following instructions.
Client Status: Not Installed
If no backup client is installed on an ECS instance, the ECS instance is not backed up. We recommend that you use the ECS file backup feature to back up important data.
To back up files from ECS instances, you do not need to manually install a Cloud Backup client. When you create a backup plan for an ECS instance, Cloud Assistant automatically installs a Cloud Backup client on the ECS instance. After the client is installed, the Client Status is Activated and the version number of the client is displayed.
Status of the restore job: Failed
Modify and confirm the configurations as prompted.
Check the status of the Cloud Backup client. For more information, see How do I troubleshoot and handle the status exceptions on a Cloud Backup client?
View the client logs and locate the error code.
Note
The Cloud Backup client is installed in one of the following paths by default. The following paths are for reference only. The actual installation path may be different.
On Windows, you can view the logs in the C:\Program Files\Aliyun Hybrid Backup Service Client\logs path.
On Linux, you can view the logs in the /opt/alibabacloud/hbrclient/logs path.
Status of the restore job: Partially Completed
Download the list of files that have not been restored, confirm them one by one, resolve the issue based on the error message, and then run the restore job again.
