title: Need a persistent place to store a backup of my Core Data store
body: <p>I have an app that creates a backup of my Core Data store and stores it in the NSDocuments directory.  When I try to restore from that directory (<em>without restarting the app</em>), everything is restored correctly.  However, <em>if I stop the app</em>, restart it and try to do a restore, the directory is different and the restore uses an old version of the backup file (haven't a clue where it came from).</p>
  
  <p>My question is:  because I need to persist the latest backup file, where can I save it so it will be there when I need it?  (possibly after many distinct executions of my app).  I don't want to use iTunes, so I was thinking of possibly iCloud; I need something that is not accessable to the user so he/she can't accidently delete the backup file.</p>
