(Exchange Server 2010/2013)
IS_NUM
You must supply this value. Because
storage groups are not supported in Ex-
change Server 2010/2013, use a value
of 1 in this case.
Number of storage groups to back
up per database server (for Exchange
Server 2010/2013, use a value of
1)

Time allowed for backing up the en-
tire system (seconds)
SYSTEM_BACKUP_TIME

About VDI generation timeout
The VDI Meta File Generation Timeout setting is located in the SQL Option tab in the Setup Application
Agent dialog box. It indicates the time it will take to back up or restore an SQL Server database. If
an inappropriate timeout value is specified, the following problems might occur:
• If too small a timeout value is specified, the backup fails due to a timeout, resulting in a failure to
back up the database.
• If too large a timeout value is specified, a client application connecting to SQL Server will time
out before the backup itself fails by timing out.
Specify a value of at least 20 minutes, or follow this procedure to determine a timeout value suitable
for your operating environment:
1. Set the VDI generation timeout to a large initial value, such as 3600 seconds.
2. Perform a backup.
3. Refer to Time for Completion in the Task Log dialog box and estimate the time it will take to
complete a normal backup.
4. Because the time it will take to complete the backup depends on the state of the system resources,
revise the VDI generation timeout to a value slightly greater than the time calculated in step 3.
