Requirements and Limitations

Replication has the following requirements and limitations:

  • [For VMs with VHD disks] If you change the size of VM disks on the source VM, Veeam Backup & Replication will delete all available restore points on the VM replica during the next replication job session.
  • Off-host replication scenario is possible only for VMs located on a SAN storage with hardware VSS provider.
  • Replication of VMs with disabled checkpoints is not supported.
  • You cannot replicate VMs with shared VHDX and VHDS disks.
  • Due to Microsoft limitations, you cannot use Microsoft Azure Active Directory credentials to perform application-aware processing on VMs running Microsoft Windows 10 (or later).
    • The backup server must be able to resolve short names and connect to source and target virtualization hosts.
    • If a job is unable to complete within 21 days period, it will be stopped with the Failed status.
