EVS implements the backup function through the Volume Backup Service (VBS). VBS allows you to create backups for EVS disks on the management console without stopping the server. When data loss or data damage occurred due to virus invasion, misoperations, or software and hardware faults, you can use backups to restore the data, guaranteeing your data correctness and security.
For details about EVS disk backup, see the Volume Backup Service User Guide.
