How Do I Select Among Database Server Backup, Cloud Server Backup, and Disk Backup?

  • Cloud server backup supports backing up certain disks or all disks on an ECS or BMS. The cost is higher than that of VBS. This backup mode is suitable for scenarios where the entire server needs to be backed up and servers need to be quickly provisioned. It is not suitable for servers deployed with databases. You can use the backup to restore data to the original server, create an image, or replicate it to another region.
  • Disk backup supports backing up EVS and DSS disks. This mode features low cost and is suitable for scenarios where important data disks need to be backed up. You can use the backup to create a new disk and attach it as a data disk to a server. A disk backup can be shared among users in the same region.
  • Database server backup: supports backing up servers where databases are deployed. The file or disk data in the database server is backed up at the exact same time, and databases are quiesced and memory data is refreshed to ensure application consistency. After the servers are restored using the backups, applications such as databases can be properly used. Other functions are the same as those of cloud server backup.
