Constraints and Limitations

VMware Backup

  • VM backups from the following VMware vSphere versions can be synchronized to the cloud: 5.1, 5.5, 6.0, 6.5, 6.7.
  • Currently, only VMware ESXi VMs can be backed up to the cloud.
  • To achieve better performance and operation experience, only the OSs listed in Table 1 allows for cloud recovery. These OSs have passed the the compatibility test. If you only need to restore data to on-premises VMware VMs, there is no restriction on the OS version.
  • The VDDK version of VMware 6.7 or earlier VMs must be 6.0.3.
  • Backups synchronized to the cloud cannot be used to create cloud servers.
  • Backups synchronized to the cloud can only be restored to existing cloud servers running the same type of OS. Recovery of partial disks on a VM is not supported.
  • Servers whose system disks are configured with LVM cannot be restored on cloud.
  • Before the restoration, configure security groups according to the procedure. Otherwise, the restoration may fail.
  • The backup bandwidth should be at least 100 Mbit/s. The sizes of disks on the VMware VMs to be backed up to the cloud should be integers in GB.
  • When recovering data on the cloud from a Windows VMware backup, the boot partition number of the source VM system disk must be 2.
  • When recovering data on the cloud from a Linux VMware backup, the system disk of the source VM can have no more than two partitions.
