We are implementing Dynamic Storage Technology and using it to adjust our backup scheme.

* Files older than 6 months are moved to shadow, weekly.
* Primary volume is backed up daily, weekly, monthly
* Shadow volume is backed up quarterly

Would it be a better idea to incorporate weekly incrementals of the shadow volume for purposes of disaster recovery? For single file restores, I should be covered with the above, but I just think it may be impossible to do a disaster recovery and get the entire file system back the way it was.

Much appreciated!
