Quoting

Amanda can parse quoted strings in most places where a simple identifier can appear, including in amanda.conf(5), amanda-client.conf(5), and the disklist(5). The syntax is shell-like -- all of the following are considered a single word:

• oneword
• "one word"
• one\ word
• one" "word
• word\\with\\backslashes (although note that you probably want to use forward slashes in a DLE diskname)
• "funny \019 characters"
• "embedded \"quotes\""
