ERO retention can use any combination of COPIES, RETPD, and GENS. When more than one retention parameter is specified, CA View will keep the report until all retention parameters have been satisfied. Thus, if you use COPIES=2 RETPD=5, CA View will not delete any copies unless they are at least 5 days old. In addition it will always keep the last 2 copies of a report, even if they are older than 5 days. This is referred as the TOTAL retention of a report.
If no ERO retention is specified (COPIES, RETPD, GENS), the INIT PARM PCOPIES is used as the default.
TOTAL retention and tape retention are nearly the same because the backup cycle copies a report to tape according to the interval settings.
You can use the SARBKTUX (user exit) to target specific reports that should not be backed up to tape.
