Working with backup sets : Cloud (Salesforce.com) backup sets (Windows) : Restoring a Salesforce.com backup set at the table level : Specifying the restore destination
 
Specifying the restore destination
In the Select Restore Location screen, select the restore destination and click Next.
Original location: This option is selected by default. Data will be restored to the original backup source location (i.e. the original Salesforce.com account) with the credentials used during backup.
Alternate location: For Salesforce.com backup sets, an alternate location can be another Salesforce account, the original location, or a different target on the same account (e.g. from Production to Sandbox or vice versa). Enter the required credentials when prompted.
