By the way, the image in the first post that you referenced shows both the "Output path" and the "Output archive" boxes checked.
I'm not trying to be silly, just trying to help. Maybe I didn't explain it well, but I was trying to explain how it works. As I understand it, the backup files for the archive function are put in a "temp" location, which is the path in the output path section, then when the archive is completed the temp files are either saved or deleted based on whether or not you have the "Output path" box checked.
I went ahead and tried my own advice on my own set up to see if my advice is good advice or not. (By the way, you can see my settings here:
viewtopic.php?f=2&t=7746&start=990#p335223) Anyways, my advice is not good advice. When I unchecked the "Output path" box and ran the backup, it basically runs the backup, then zips the folder, then deletes all of the backup files, including the zipped folder. Here is the results box I get.

So I've been of no help to you.

Try this instead. You need to take your output path and location of your output archive to another level. As you have it set up now, the script deletes all of the backup files located in the "Temp" folder because you told it not to save them. And since the zipped Archive is located in that folder, it is getting deleted along with all of the temporary backup files. All you have to do is create a separate folder for the temp files to be located in and eventually deleted.
You can either setup your backup more like the image in the first post that you referenced, or you can do it this way. Go into your "Temp" folder and create a "MMBackup" folder. Within that newly created "MMBackup" folder, create a "Files" folder and an "Archive" folder. Then try this setup instead and it should work for you.
Output path: "C:\Temp\MMBackup\Files\"
Output archive: "C:\Temp\MMBackup\Archive\Mediamonkey.zip"
That way when the script is done creating the zipped archive, it will only delete the files in the "Files" folder, and not the zipped folder in the "Archive" folder.
That should work for you, but let me know how it goes.
By the way, I would recommend that you also check the "Output path" box. That way you will have one more copy of your backup. Redundancy never hurts when it comes to backups. I would also add the date and time feature to your zipped archive. As you have it now, your previous zipped folder will be overwritten every time you run the backup script. If you add the date and time to the zipped folder name, then the new zipped folder will be created next to the old zipped folder. That way when things go bad, you will be able to choose which backup to restore from. Check out my backup settings to see how I have it setup. It works pretty sweet for me.
