It is a bad idea to back up more than a few mailboxes. Here is a cut and paste of legato admin manual:
Backing Up Individual Mailboxes
With BusinesSuite Module 2.0 for Microsoft Exchange Server, you can
separately back up and recover individual mailboxes in an Exchange Server
Information Store. This feature is useful for archiving a user’s mailbox;
however, it is not a replacement for backup and restore of an entire Exchange
Server Information Store.

How to Schedule a Mailbox Backup
In NetWorker Administrator on the NetWorker server host, perform the
following tasks:
1. Use the Group resource in NetWorker Administrator to configure a
NetWorker backup group to perform the Exchange backup.
3
2. Edit the Group resource as follows:
a. From the Edit Group dialog box, click the General tab, and enable the
Autostart option for the group.
b. In the Backup Level field, enter Full for the backup level. (Only full
backups are supported.)
c. In the Activity Timeout field specify a large number (for example,
more than 300).
d. In the Schedule field, choose a schedule. To create one of your own,
use the instructions in “Chapter 2: Backup Types and Levels”of this
guide.
3. Create a Client resource for the Exchange server.
4. Edit the Client resource as follows:
a. From the Create/Edit Client dialog box, click the General tab.
To specify a backup of all mailboxes on your Exchange server, enter
the save set value MSEXCH:MB in the Save Set text box.
Important: Do not use the save set value MSEXCH:MB if you have a large
number of mailboxes configured on your Exchange server (say, more than
thirty). Performance on your Exchange server will be extremely slow and
recovery uncertain if you use this save set to back up a large number of user
mailboxes.
– To specify a limited number of individual mailboxes for backup,
enter the mailbox names on separate lines, without quotation
marks, as shown in the following example:
MSEXCH:MB/George Gershwin
MSEXCH:MB/Irving Berlin
MSEXCH:MB/Leonard Bernstein
MSEXCH:MB/Aaron Copeland

Important: To schedule a backup for a large account (say, more than four
mailboxes), you might use the -I input-file command-line option. See the
next section, “How to Schedule a Backup of Multiple Mailboxes” for complete
instructions.
b. In the Remote tab of the Create/Edit Client dialog box, enter the
following:
– In the Remote Access text box, enter the names of users and hosts
that will be allowed to back up client files.
– In the Backup Command text box, enter nsrxchsv.exe.
5. Start the Exchange backup group from NetWorker Administrator
manually, or allow it to run at the scheduled time.
How to Schedule a Backup of Multiple Mailboxes
To schedule a backup for multiple mailboxes, you must enter the -I
input-file option in the Backup Command text box in NetWorker Administrator.
The -I input-file option reads the mailbox names to be backed up from a
text file that you specify (the input file). When you need to add or remove
individual mailbox names, edit the input file.
1. Use a text editor to create an input file. Enter the names that you want to
back up on separate lines, without quotation marks, as shown in Figure 5:
Figure 5. Example Input File
2. Save the input file to the default directory, which is the installation
executable path specified on the NetWorker client.
3. Use the Group resource in NetWorker Administrator to configure a
NetWorker backup group to perform the Exchange backup.

4. Edit the Group resource as follows:
a. From the Edit Group dialog box, click the General tab, and enable the
Autostart option for the group.
b. In the Backup Level field, enter Full for the backup level. (Only full
backups are supported.)
c. In the Activity Timeout field, specify a large number (for example,
more than 300).
d. In the Schedule field, choose a schedule or create one of your own
using the instructions in “Chapter 2: Backup Types and Levels”of this
guide.
5. Create a Client resource for the Exchange server.
6. Edit the Client resource as follows:
a. From the Create/Edit Client dialog box, click the General tab.
To back up multiple mailbox names from the specified input file,
enter the save set value MSEXCH:MB in the Save Set text box.
b. In the Remote tab of the Edit Client dialog box, enter the following:
– In the Remote Access text box, enter the names of users and hosts
that will be allowed to back up client files.
– In the Backup Command text box, enter the following:
nsrxchsv.exe -I input-file-name
7. Start the Exchange backup group from NetWorker Administrator using
the “Group Control” feature, or allow it to run at the scheduled time. Refer
to the Legato NetWorker Administrator’s Guide for instructions on using the
Group Control feature.
Viewing the Results of a Backup
NetWorker provides several reports about the results of a backup:
• A series of messages written to the NetWorker message log files.
See “Appendix A: Error Messages” on page 79 for more information about
NetWorker and NetWorker XBSA messages.
• A scrolling list of messages displayed in the Group Control window of
the NetWorker administration program.
These messages are displayed in three lists: pending save sets, completed
save sets, and failed save sets.
• A “savegroup completion” notice upon completion of a scheduled
backup.
If you are using a NetWorker server for UNIX, you can also send an e-mail
notification of the results of a scheduled backup to the owner of a save set.
Use the “View Details” option to edit the NetWorker client resource for the
computer running BusinesSuite Module for Exchange. Edit the Owner
Notification attribute and enter a notification command directed to the
login ID of the owner.
You can edit the notification setup for this report using the Customize
feature of the NetWorker administration program. Refer to the section on
setting up event notifications in the Legato NetWorker Administrator’s Guide
for details on using the NetWorker administration program to customize
your notifications.
The Legato NetWorker Administrator’s Guide provides complete details about the
reports generated by NetWorker.
Chapter 4 provides information on performing a manual backup of Microsoft
Exchange Server.
