VBS Operation Instances
This section explains how to use VBS to ensure data security in different scenarios, its limitations, and its typical operations.
Scenarios
VBS applies to the following scenarios:
- Hardware faults
Production storage devices on the cloud platform have faults.
- Software faults
System faults cause data losses (for example, the system malfunctions and the system incorrectly delivers resource deletion commands) and application system faults on a user's guest OSs.
- User misoperations
User misoperations cause data loss and system bootup failures.
Requirements and Limitations
- EVS disks cannot be restored in a batch.
- If you use data backups to create an EVS disk, the new EVS disk cannot be used as a system disk.
EVS Disk Data Backup
VBS works only on EVS disks. For details, see Creating a VBS Backup.
EVS Disk Data Restoration
You can use a VBS backup to restore an EVS disk to the time when the backup was created.
Before restoring the disk data, stop the server to which the EVS disk is attached and detach the EVS disk from the server. After the restoration is complete, re-attach the EVS disk and start the server. For details, see Data Restoration Using a VBS Backup.
Creating an EVS Disk Using a VBS Backup
After an EVS disk is created using a data backup, the initial data of the new EVS disk is the same as the initial backup data. For details, see Creating an EVS Disk Using a VBS Backup.
