Data set naming conventions

Give unique names to the logs and backup data sets so that you can easily distinguish them from the operational data sets.

If you have no suitable naming convention, create one for all future backups and logs. MVS™ data set names can be 1–44 characters, divided into qualifiers of up to 8 characters. Here are some examples:
clustername.BU.Ddate.Ttime
For backup data sets of VSAM base cluster clustername.
logstreamname.COPY1.Ddate.Ttime
For the first copy of an MVS log stream logstreamname. The date and time might be the time that the copy was made.

Here are examples of data set names that follow these naming conventions:

PAYROLL.BASE.BU.D01159.T235205 A backup data set

PAYROLL.LOGSTREAM.COPY1.D01200.T232145 A copy of an MVS log stream
