Occasionally you may need to archive a copy of a webpage or your cloud data for future reference. You may need to retain regular (weekly or daily) snapshots of certain sites that change regularly, for example stock listings. Not just that, a snapshot of your cloud data can be useful if the site temporarily goes down. I had this problem last week as my online to-do list app, Wunderlist , went offline for several hours.
