Backup

Scenarios

A backup is a complete copy of an SFS Turbo file system at a specific time and it records all configuration data and service data at that time.

For example, if a file system is faulty or encounters a logical error (for example, mis-deletion, hacker attacks, and virus infection), you can use data backups to restore data quickly.

Creating a File System Backup

Ensure that the target file system is available. Or, the backup task cannot start. This procedure describes how to manually create a file system backup.

1. Log in to CBR Console.
2. In the navigation pane on the left, choose SFS Turbo Backups.
3. Create a backup vault by following the instructions in section "Creating an SFS Turbo Backup Vault" in the Cloud Backup and Recovery User Guide. Then, create a backup by following the instructions in section "Creating an SFS Turbo Backup."
4. The system automatically backs up the file system.

   You can view the backup creation status on the Backups tab page. When the Status of the backup changes to Available, the backup has been created.

5. If the file system becomes faulty or an error occurred, you can restore the backup data to a new file system. For details, see Using a Backup to Create a File System.

Using a Backup to Create a File System

In case of a virus attack, accidental deletion, or software or hardware fault, you can use an SFS Turbo file system backup to create a new file system. Data on the new file system is the same as that in the backup.

1. Log in to CBR Console.
   1. Log in to the management console.
   2. Click in the upper left corner and select your desired region and project.
   3. Choose Storage > Cloud Backup and Recovery > SFS Turbo Backups.

2. Click the Backups tab and locate the desired backup.
3. If the status of the target backup is Available, click Create New File System in the Operation column of the backup.
4. Set the file system parameters. See Figure 1.
   Figure 1 Create File System
   
   

   • For detailed parameter descriptions, see table "Parameter description" under Creating an SFS Turbo File System.

5. Click Next.
6. Go back to the file system list and check whether the file system is successfully created.

   You will see the file system status change as follows: Creating, Available, Restoring, Available. You may not notice the Restoring status because Instant Restore is supported and the restoration speed is very fast. After the file system status has changed from Creating to Available, the file system is successfully created. After the status has changed from Restoring to Available, backup data has been successfully restored to the created file system.
