Restore CPFS - Cloud Backup - Alibaba Cloud Documentation Center

After you back up CPFS files to a backup vault using Cloud Backup, you can restore the files if they are lost or damaged. From a backup point, you can restore all files or a subset of conditional files to the source CPFS or a new CPFS.

Prerequisites

You have completed a CPFS backup.
You have the required permissions for Cloud Backup. If you use a Resource Access Management (RAM) user, ensure that the user has the necessary permissions.

Billing

The restore feature is free of charge. For more information, see Billing methods and billable items.

Notes

The file restore speed depends on the number and size of the files. Restoring many files can take a long time. For more information, see File backup and restore speeds. The data provided is from a staging environment and is for reference only.
To use a new CPFS as the restore destination, you must first add it as a data source in the Cloud Backup console.
If you restore files to the original path or a specified path, any existing files with the same name in the destination path will be overwritten. Check the data in the destination path before you restore.

Create a restore job

Log on to the Cloud Backup console.
In the navigation pane on the left, choose Back Up > CPFS Backup.
In the upper-left corner of the top menu bar, select a region.
On the Protected CPFS Data Sources tab, find the target CPFS data source and click View Details on the right.

Note
If you use the legacy console, which shows Try New Version in the upper-right corner, find the target CPFS data source on the Data Source List tab.
In the Backup History section, find the target backup point and click Restore in the Actions column.

Alternatively, click the icon on the right side of the backup history to switch the display mode. Then, click the target backup point and select Restore.

Note
Choose an appropriate backup point. Backup data may vary across different backup points.

Note
The Actions column in the backup history also provides the Browse and Delete options. Use Browse to view the contents of a backup point before you restore it.

In the Create Restore Job panel, configure the parameters.

Select Select Restore Items, and then click Next.

Parameter

Description

Restore Items

Configure the files or folders to restore. The restore rules include the following three options. The options are mutually exclusive, and only one can be active at a time.

Include All Files: Restores all files from the source client.
Include Files or Exclude Files: Select the files to include or exclude. You can also enter a list of files to include or exclude. Cloud Backup then restores the specified files from the source client based on your rule.
- Select files manually
- Enter a file list manually
  
  Enter one path per line in the file list. Each line must start with the last folder of the source backup path.
  - Restore specific files
    
    For example, if the source path is folder/test/data and you want to restore file.txt and abc.png from the data folder, enter the following in the file list:
```
/data/file.txt
/data/abc.png
```
  - Restore a specific folder
    
    For example, if the source path is folder/test/data and you want to restore all files and subdirectories in the data folder, enter the following in the file list:
```
/data/
```
  - Restore files or folders that match a wildcard character
    
    For example, if the source path is folder/test/data and you want to restore files or subdirectories in the data folder that have the prefix `abc`, enter the following in the file list:
```
/data/abc*
```

Configure the Restore Destination, and then click Next.

Select the target CPFS data source. You can choose the source CPFS data source or a new one. If you want to restore to a new CPFS, you must first add it as a data source in the Cloud Backup console.

Configure the Destination Path, and then click OK.

Important

Ensure the restore path exists. Otherwise, the restore job fails.

Parameter	Description
Restore Path Type	Specify Path: Restores files to a specified path. If you select this option, enter the destination path in the Destination Path field. Origin Path: Restores files to the original path where they were located at the time of backup.

After the restore job is created, you can view its progress in the Status column on the Restore Jobs tab.
