But the thing about the archive bit is that it is part of the clip library, and it gets set automatically by Discreet apps when something is archived. So if what I want to do is simply figure out what hasn't been archived yet, all I need to do is traverse all clips/libraries/projects and get a list of libraries which contain clips where the archive bit hasn't been set. I'm not trying to archive outside of Backdraft, so I'm not trying to change that bit, just have access to it.
And if the person in charge of the Backdraft archive misses something, or a new clip gets created in the meantime while I'm running my script, it doesn't really matter: the next time you run the script, it will flag that clip as not having been archived yet.
I remember that the "archived flag" was a long-standing request in Flame, before that people had no idea what had been archived or not.
Longer term, I would really like to see WireTap expose some API for full support of file archives (at least creating them). I would love to be able to create file-based archives from code executed from a cron job, and which inerfaces with a MuSQL database to keep track of what has been backed up when and where. It's a bit silly to have to spend time in front of the application GUI to perform a task which would be done more efficiently and accurately by a script.
