The autosave files include the changes of your database written
to the log. They do not include the content of your database 
when autosave starts.

Yes, backups are not independent from the os.

Start a recovery immediately after the "init config" step (without 
db_warm) with restoring a full data save.

This looks like another problem. Check the knldiag file for more infomation.

Summary: 
  With autosaves only you can not restore a totally destroyed database.
  You will need at least one full data backup and a series of autosaves
  matching to the data backup.
