By design, you cannot change an existing archive.  However, you can make use
those the current archives and our deduplication algorithm to reduce the
amount you need to upload.  I suggest:

1) create a new archive (with your exclusion list).  This will upload almost
no data -- it will only upload any changes to files that happened in the past
day (or whenever you created your earlier archives).

You can read more about deduplication here:

2) check that your new archive contains the files you want.

3) delete your old archives.

If you remove your old archives before uploading a new one, you'll need to
reupload everything.  Much better if you delete them afterwards.  :)


(more advanced users could try using the @@archive-name trick, but I think the
above set of instructions is easier to understand)
