Volume Backup Service (VBS) provides snapshot-based data protection for Elastic Volume Service (EVS) disks on Elastic Cloud Servers (ECSs). VBS supports both full and incremental backups. A full backup is performed at the first time, and the follow-up backup operations are all incremental backups. You can use data backups generated by either the full or incremental backup to revert EVS disks to the state when the backup is created.
Open Cloud VBS is easy to use, and you can perform online, one-click backup and restoration for system and data disks of ECSs.
