NG 14 - Restoring recovery points

Hi... question applies to Norton Ghost 14.

 

1.  Under the option to Recover My Computer, if you select the latest incremental recovery point backup (*.IV2I), does it bring along (restore) all other incrementals and the last entire base recovery point (*.V2I)?

 

2.  Is there a strategy or reason behind how many incrementals to use for each base recovery?  Weekly base recovery point?  Bi-weekly?  Do you risk failure with too many incrementals?

 

Thanks,  Tom
