You can also opt to store the archive files after the deletion step: To do this you must flag the checkbox Deletion run before file storage in archiving object-specific customizing.

If security is your main concern, then you should not run the deletion program until after the archive files have been stored. In this way you know that the data will only be deleted from the database after the archive files have successfully been moved to the external storage system. In addition, you can set the system to read the data from the storage system and not from the file system.

However, if your main concern is the performance of the archiving programs, then you should schedule the deletion program first and then store the files.
