name

A unique name (within the transfer project) assigned when the job is created. If this field is empty in a CreateTransferJobRequest, Storage Transfer Service assigns a unique name. Otherwise, the specified name is used as the unique name for this job. If the specified name is in use by a job, the creation request fails with an ALREADY_EXISTS error. This name must start with "transferJobs/" prefix and end with a letter or a number, and should be no more than 128 characters. For transfers involving PosixFilesystem, this name must start with transferJobs/OPI specifically. For all other transfer types, this name must not start with transferJobs/OPI. Non-PosixFilesystem example: "transferJobs/^(?!OPI)[A-Za-z0-9-._~]*[A-Za-z0-9]$" PosixFilesystem example: "transferJobs/OPI^[A-Za-z0-9-._~]*[A-Za-z0-9]$" Applications must not rely on the enforcement of naming requirements involving OPI. Invalid job names fail with an INVALID_ARGUMENT error.
