F5 Automated Backups - The Right Way

After the SFTP scheduled backup runs, it doesn't seems to delete the file in /var/local/ucs folder. Is there a way to be sure that the deletion is in place? I have this message in the log file Script (/Common/f5.automated_backup) generated this Tcl error: (script did not successfully complete: (+-----------------------------------------------------------------------+ | WARNING | | ------- | | | | The programs and data stored on this system are licensed to or are | | private property of this company and are lawfully available only to | | authorized users for approved purposes.
