Example 1
ON DATASET=BKP*
DO RETENTION=CYCLES 0010 PREFIX Y
If another version of any of these files is created, they will have exceeded their retention period (ten cycles) and the oldest version is scratched.
Example 2
ON DATASET=BKP*
DO RETENTION CYCLES 0010 PREFIX N
If another version of any of these files is created, their individual counts will not have exceeded their retention period (ten cycles). Therefore, all the versions of the files are retained.
Example 3
Save (retain) backup volumes or data sets for one year (365 days).
