Is individual mailbox backup and public folder backups supported with exchange 2010 with netbackup 7.0.?
I'm not sure what you're asking, but I believe the answer is no:
Symantec NetBackup (tm) 7.0 for Microsoft Exchange Server Administrator's Guide (pages 58-9):
Policy recommendations for Exchange Server 2010
Refer to the following recommendations when you create policies for an Exchange
Server 2010 Database Availability Group (DAG):
■ Create a policy that backs up an entireDAGor one or more databases in a DAG.
This policy supports full, incremental, and user-directed backups.
To perform a backup with Granular Recovery Technology (GRT) select the
Enable granular recovery option. Then you can restore databases and
individual mailbox and public folder items. You cannot restore individual
mailbox and public folder items from any incremental backups.
■ MAPI mailbox and public folder backups are not supported with Exchange
