+What git-annex actually does when a repository is in multiple groups
+is that the "standard" preferred content expression has no effect.
+Because this is an ambiguous configuration and it's not clear what you
+want.
+
+I don't think that you can combine preferred content expressions for
+multiple groups and always get behavior that makes sense. In particular,
+it seems likely that in some situations you'd want to combine them with AND
+but in other situations with OR.
+
+So, the best thing for you to do is probably to manually write a preferred
+content expression that clearly expresses what you want. Note that you
+can have a repository that's in the archive group, but instead of "standard"
+has its own custom preferred content expression. In your case, I think you
+want to do that; keeping the repository in the archive group will retain
+the behavior of other repositories dropping archived files once they reach
+it.
+
+Seems that for the preferred content setting for this repositry, you
+want the same one used for backup repositories, "anything".
+
+So:
+
+	git annex group . archive
+	git annex ungroup . backup
+	git anenx wanted . anything
