Questions To Ask & Address Prior To Doing A User Restore

  • Can data be restored from the user's dumpster [if enabled] ?
  • Is there a copy of the data in a third party client ? [POP email client that downloaded it, for example]
  • Does the data maybe exist in another user's account ? [For example, the senders account or others in the To/CC]
  • Does the data reside in a redolog/s ?
  • Finally, restore from backups ?
    • Do I need to overwrite the existing account with the restore or should I restore to a new account name?
      • Using the option -ca [create account] and -pre restore_ [prefix to the new account name, restore_user@ ]
    • What are your retention policies and how it might determine the backup set you need?
