Hi,
The best option these days is to use GRT (Granular recovery technology). See the note on how to configure this option. Please note that you have to use disk as a storage destination (storage unit) to perform these backups. You can move the images from disk to tape later. The amount of disk would depend on your information store sizes and the retention period you'd like to keep the GRT backups on disk.

Alternatively you can use the MAPI mailbox backups but these are usually very slow. And require two separate backups where GRT requires only one to provide DR recovery as well as the capability to restore individual items from/to a mailbox.
To improve performance you can specify mulitple streams when backing up mailboxes i.e. A-M and M-Z etc. The same can be done on a GRT backup, but it works with storage groups instead of mailboxes. This all depends on your environment and performance, so you'll need to test and play around to find the best fit.

Hanging or just dog-slow?
Please this O-L-D but still valid TN: http://www.symantec.com/docs/TECH38737
The first concern expressed by most people with regard to mailbox backups is performance. It is important to note with mailbox backups, throughput is expected to perform at speeds that are 10% of the exchange information store throughput. Some things which can be done to improve performance include:
It is also important to check the Windows account which starts the NetBackup Client Service. The account must have Exchange Full Administrator rights and Local Administrative rights to the Exchange server. Running the NetBackup Client Service as the Local System account will not allow Exchange Mailbox backups to be successful.
