Refer to the sections below to learn about possible causes of the following errors:

  • “Backup/replication/recovery of the VM has failed”
  • “An error has occurred while backing up/replicating/recovering one or more disks of the VM.”

Network or Environment Configuration Problems

Incorrect IP/DNS Configuration

There can be problems with resolving source or target host DNS names on the machine where the Transporter is installed. Also, the source or target host can have multiple IP addresses in different networks, and some of them might not be reachable from the Transporter. Please make sure the source and/or target host can be pinged from the appropriate Transporter machine. If ping fails, please try to edit the HOSTS file on the Transporter machine and specify the proper DNS name and IP address.

Closed Ports

The product requires a number of TCP ports to be open in order to operate successfully. These ports include:

  • Director Web HTTPS port (4443 by default): used to access the Web UI of the product. It must be open on the machine where the product is installed.
  • Transporter Port (9446 by default): used for communication with Transporters. It must be open on every machine where the Transporter is installed (including the Director one).
  • Data transfer ports (9447-10000 by default): ports from this range are used for the VM data transfer. This range must be open on every machine where the Transporter is installed (including the Director one).
  • VMware Web Services Port (443 by default): used to access VMware infrastructure. It must be open on source and target hosts used for VM backup, replication, or recovery.
  • VMware Data Transfer Port (902 by default): used to access VMware infrastructure. It must be open on source and target hosts used for VM backup, replication, or recovery.

Please make sure all the described ports are not blocked by firewall, as this may be the cause of the above error.
