You need disk backups for GRT - Basic or Advanced.

The reason for that is that the disk backup must be network-mounted to a drive letter on the Exchange Server so that individual items can be accessed.

Full details in the Exchange Server Administrator's Guide  http://www.symantec.com/docs/TECH127056

Also have a look at this post under Featured discussions at the top of the NBU forum page:

so that means....we'll have to go for disk based bakups only.....

now i m stuck...let me brief my environment:

master servr-solaris10 (will be upgraded to 7.0.1), library - L180 storage tek, lto4 drives attached

no media server, master will act as media

Ten exchange 2010 sp1 DAG boxes where 2 servers hosting exchange database.

Now i want to take backup of these exchange servers and ensure the mailbox level restores.

my library is at a quite distance from the exchange databse boxes. so we have to take backup over the wan...but now as we  to go for disk based backups only.....because GRT supports only on disk.

wht can be done now??

pls provide some solutons...

You don't need disk backups only - you can provide disk space to hold 2 - 3 full backups and let it stage to tape. If you need to restore from an older backup that is no longer on disk, you can duplicate it back to disk and promote the disk image to primary.

that will be a tedious task......

ok if i am taking mailbox backups on disk.....

for exchange database backup...can i put them on tape directly or i'll have to backup that via disk only...
