Reference

The VBS service provides the data backup function for EVS disks. Data backups can be used to create EVS disks.

Data Restoration Using a VBS Backup

Both CSBS and VBS are backup services and provide backup protection for tenant data. The backup generated by CSBS is also displayed on the VBS page. Table 2 describes the differences between CSBS and VBS.

Backup and restoration objects

All EVS disks (including system and data disks) on a single ECS

One or more specified EVS disks (system or data disks)

Recommended scenario

An entire ECS needs to be protected.

Only data disks need to be backed up, because the system disk does not contain personal data.

Advantages

All EVS disks on an ECS have consistent data. They are backed up at the same time, eliminating the problem of data inconsistency caused by backups generated at different points in time.

Data is secure while the service is cost-competitive.
