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
