If blank, archived artifacts from all environments will be restored.

Where the same named artifact exists in multiple environments, it is undefined as to exactly which of the duplicates will be restored.

If non-blank, the value is treated as a list of environments from which to copy from. Environments can be separated by whitespace or commas. If necessary \ can be used to escape characters and matching ", ' or `s can be used to quote the environment. For example, the value: java, "maven 3.0.4" 'maven "2.2.1"', `maven \`any\`` will match any environment build containing at least one of the components: java, maven 3.0.4, maven "2.2.1" or maven `any`
