Backing Up an SFS Turbo File System

Scenarios

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

If a file system is faulty or encounters a logical error (such as an accidental deletion, a hacker attack, or virus infection), you can use data backups to quickly restore data.

Creating a Backup on the CBR Console

Ensure that the status of the file system you want to back up is Available. Or, the backup task cannot start. This procedure describes how to manually create a file system backup

When an SFS Turbo Standard, Standard-Enhanced (discontinued), Performance, or Performance-Enhanced (discontinued) file system is being backed up, mounting the file system may fail. This is because the connection used for mounting may experience an I/O delay about 30 seconds. You are advised to perform backup during off-peak hours.

1. In the navigation pane on the left, choose SFS Turbo Backups.
2. Wait for CBR to automatically create a file system backup.

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

3. Create a new file system from the backup if the file system becomes faulty or encounters an error occurred. For details, see Using a Backup to Create a File System.

Creating a File System from a Backup on the CBR Console

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

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

2. Click the Backups tab and locate the desired backup.
3. Click Create File System in the Operation column of the backup. The button is available only when the backup status is Available.
4. Configure the file system parameters.
   

   • To learn more about these parameters, see Table 1.

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. 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.
