the file has to be transferred if the transfer to the
primary destination fails. Failure occurs when the file

destination for some reason. Some common reasons for such
failures are listed out in CdcFileXferStatus.
The specified URL should contain the base-name of the remote
file, the suffix will be carried over from the name of the
VFile being tranferred, and will be automatically appended by
the agent.
This object's value may be modified at any time.
