thanks Nagalla... NBU version is 7.5.0.6 recently upgraded from 7.1.0.4. these DAG images were done by 7.1.0.4.. how can i get them duplicated as am already on 7.5.0.6?

i am really not sure...

i had different kind of issue with Exchage backups for restore  and resolved by upgrading it.. and symatec confimed that what ever the images backed using the older version will have the issue and  only the backup happend after the upgrade will be reflected by the fix.

so i ended up leaving the old images.. 

so i would suggest.. see if you are seeing the same issue for the images that are being backup after the upgrade..

if not check with symatec support if they can comment on the images that occured in older versions.

not seeing the same issue after the upgrade on the newly created images.. they are being backed up, replicated and duplicated okay by SLP's..... 

cant afford to leave the old images as my customer is actively waiting on us to restore some mailboxes out of those images... any other ideas?
