Before You Begin

Before you create a VMware Cloud Director replication job, check the following prerequisites:

• Check the supported Cloud Director versions in Supported Platforms and Applications.

• You must add VMware Cloud Director server to the backup infrastructure. The backup server must be able to resolve short names and connect to source and target virtualization hosts.
• You must set up the organization VDC that will keep the replicas.
• You must disable the VM discovery option in VMware Cloud Director settings. For more information on where you can change the option, see VMware Docs.
• VMware Cloud Director replication does not support replication of a vApp to a Cloud Provider.

• If you plan to replicate VM containers using WAN accelerators, source and target WAN accelerators must be added to the backup infrastructure and properly configured. For more information, see Adding WAN Accelerators.
• If you plan to replicate VM containers using WAN accelerators, it is recommended that you pre-populate global cache on the target WAN accelerator before you start the VMware Cloud Director replication job. Global cache population helps reduce the amount of traffic transferred over WAN. For more information, see Manually Populating Global Cache.
• If you plan to use pre-job and post-job scripts or pre-freeze and post-thaw scripts, you must create scripts before you configure the VMware Cloud Director replication job. Veeam Backup & Replication supports script files in the following formats: EXE, BAT, CMD, JS, VBS, WSF, PS1, SH. For more information, see Pre-Freeze and Post-Thaw Scripts.
• You must check limitations for replication. For more information, see Considerations and Limitations.
• Due to VMware vSphere limitations, if you change the size of VM disks on the source VM, all VM snapshots that were created previously, will not be available for failover, failback and other subsequent operations. For more information, see this VMware KB article.
