How to restore large-scale file systems - Cloud Backup - Alibaba Cloud Documentation Center

After you back up files from a large-scale file system to a backup vault by using Cloud Backup, you can restore the files based on historical backup points if the files are lost or damaged. You can restore all backup files or files that meet the specified conditions. You can restore backup files to the source large-scale file system or restore backup files to a new large-scale file system.

Prerequisites

A large-scale file system is backed up. For more information, see Back up a large-scale file system.

Billing

You are not charged for the restore feature. For more information, see Billing methods and billable items.

Usage notes

The backup speed and recovery speed of Cloud Backup are obtained in a test environment. The values are provided for reference only. For more information, see Backup speed and recovery speed.
To restore a large-scale file system to a new large-scale file system, you must add the destination data source in the Cloud Backup console.

Create a restore job

Log on to the Cloud Backup console.
In the left-side navigation pane, choose Backup > Large-scale File System Backup.
In the top navigation bar, select a region.
On the Large-scale File System Backup page, find the data source that you want to restore and click the icon.
Click an available historical backup point and then click Restore.

In the Create Restore Job panel, perform the following steps.

In the Select Restore Items step, configure the Restore Items parameter and click Next.

Parameter

Description

Restore Items

The files or folders that you want to restore. The following restore policies are supported:

Include All Files: All files on the client are restored.
Include Files or Exclude Files: You can manually select the files to include or exclude, or enter a list of files to include or exclude. Then, Cloud Backup restores the specified files on the client based on the restore policy.
- Select the files that you want to include in or exclude from the restore job
- Specify the files that you want to include in or exclude from the restore job
  Enter one path in each line and make sure that each path starts with the lowest-level directory in the source path that is backed up.
  - Restore specific files
    For example, if you want to restore the file.txt and abc.png files in the folder/test/data directory, enter the following paths:
```
/data/file.txt
/data/abc.png
```
  - Restore specific directories
    For example, if you want to restore all the files and subdirectories in the folder/test/data directory, enter the following path:
```
/data/
```
  - Restore files or directories that match a condition containing wildcards
    For example, if you want to restore the files and subdirectories whose names are prefixed with abc in the folder/test/data directory, enter the following path:
```
/data/abc*
```

In the Restore Destination step, specify a destination for data restoration and click Next.

Parameter	Description
Destination Type	Only Large-scale File System is supported. The destination can be the source large-scale file system or a new large-scale file system. To use a new large-scale file system as the destination, you must add the file system as a data source in the Cloud Backup console in advance.

In the Destination Path step, specify the recovery path and click OK.

Important

You must make sure that the recovery path exists. Otherwise, the restore job fails.

Parameter	Description
Restore Path Type	Specify Path: restores files to the path that you specify. Origin Path: restores files to the path from which the files are backed up.
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.

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