Telefonica Background

VBS provides online one-click backup and restoration for system and data disks on ECSs, enhancing data security. If an EVS disk is faulty or a logical error occurs at the EVS disk data, tenants can use data backups to restore data quickly.

By default, VBS executes a full backup for an EVS disk that has not been backed up, and performs incremental backups subsequently. When full backup is executed, the data actually stored in EVS disks will be backup. When incremental backup is executed, the changed data since the last backup will be backup. Both full backup and incremental backup can restore an EVS disk to the state at the backup point in time.
