Hi Rick,

I understand the concern but nothing in the pipeline at this time that I am
aware of to implement the optimized backup. One thing you can do is open an
RFE at http://www.ibm.com/developerworks/rfe/?BRAND_ID=90 to request this
be implemented.

If you open the RFE, consider posting the number here, so other interested
users can link to it and add their "me too" to the RFE.

Regards,

- Andy
