Exchange 2010 DAG and backing up multiple stores

PaulN
Level 3

I want to find out if netbackup can back up more than one store at a time.  Doing 1 at a time and having to cycle through all the stores is taking too long.  I get about 100gb (30mbps)  an hour, but that is still too slow to get everything within 24 hours. i also have all the consistency checks disabled.

 

thanks

Yes - see this extract from NBU for Exchange guide:

 

Performing Exchange backups with multiple data streams
When you enable multiple data streams, backups are divided into multiple jobs.
Each job backs up only a part of the backup selections list. To use multiple data
streams, enable Allowmultipledatastreams on the Attributes tab for the policy.
You can choose to have NetBackup automatically determine where to begin new
streams by adding an asterisk (*) after the directive. Or you can control where
each stream begins by inserting the NEW_STREAM directive at a certain point
or points in the backup selections list. If you use wildcard characters to define
Exchange objects in the backup selections list, those objects are backed up in
multiple streams.
When you back up multiple Exchange 2010 databases, NetBackup groups the
backup jobs by the selected server. One snapshot is performed for all of the
replicated databases on a given server. Another snapshot is performed for all the
active databases on the server. Multistreaming then applies to the database
backups that are performed on each snapshot.
....
 
Availability Groups (DAG)s
When you back up databases in a Database Availability Group (DAG), NetBackup
selects the server to back up each database according to your data source and
preferred server list settings. The backup jobs are grouped by server. From your
backup selections list, all of the databases that have passive copies on a given
server are grouped under one snapshot job. They are then backed up by one or
more child backup jobs. All of the databases that have active copies on the server
are grouped under another snapshot job, followed by one or more backup jobs.
....
 
Ensure that MPX setting in schedule is set to 2 or more, and Max Jobs per Client in Master server Global attributes is set to more than 2.

This has worked successfully.  I have got my 4tb exchange database FULLs to 8 hours. 

thanks for your suggestions.
