There are times when Production Control needs to back up files and do nothing else. Such a job must be available. Such files use resources. Avoid using procedures when JCL is used in only one job. Procedures introduce problems.
Temporary changes become more difficult.
Overall, an additional level of complexity is added. New backup files should be sent offsite daily. Forgotten datasets will not be kept forever. An acceptable alternative is to use the locally written utility, OIS174. Prevents JCL errors.
