It is not very useful to just delete the data again after a failure, as it might be useful for debugging. Just store it into an "errors" subdirectory of the PWD in the hope that this is a sane location. Note that it'll error out if the directory already exists, but that should be acceptable in all cases. i.e. it won't exist in the CI and developers can just wipe the directory.
