Comment 4 for bug 1018154

Given that any application developer can decide to store their cache and/or history and/or temporary files in whatever specific location they like, rather than in ~/.cache, Déjà Dup can't be expected to maintain a list of cache locations to exclude.

Cache directories can be added manually to the exclude list one by one, as Ken did, but it would be nice if the user could also exclude them by extended shell globbing patterns, as in **[cC]ache* (the user's responsibility to make sure that the patterns they use cover exactly what they want to exclude). And this of course leads to bug 374274.
