The versions data deleted attribute specifies the maximum number of different backup versions retained for files and directories that you deleted.
This parameter is ignored until you delete the file or directory.
If you delete the file or directory, the next time you run an incremental backup, the active backup version is changed to inactive. Tivoli® Storage Manager deletes the oldest versions in excess of the number specified by this parameter.
The expiration date for the remaining versions is based on the retain extra versions and retain only version parameters.
