Session Messages Binary Files (SMBF)
SMBF records
The Session Messages Binary Files part stores session messages generated during backup, restore,
copy, and media management sessions. One binary file is created per session. The files are grouped
by year and month.
SMBF size and growth
The SMBF size depends on the following:
• Number of performed sessions
• Number of messages in a session
One session message occupies approximately 200 bytes on Windows and 130 bytes on UNIX
systems. You can change the volume of messages displayed when backup, restore, and media
management operations are performed by changing the Report level option. This influences the
amount of messages stored in the IDB.
SMBF location
The SMBF is located in the following directory:
<Data_Protector_program_data>\db40\msg (Windows Server 2008),
<Data_Protector_home>\db40\msg (other Windows systems), or
/var/opt/omni/server/db40/msg (UNIX systems).
You can relocate the directory by editing the SessionMessageDir=FullPathToTheMessageDir
variable in the global options file.
Serverless Integrations Binary Files (SIBF)
SIBF records
The Serverless Integrations Binary Files part stores raw NDMP restore data. This data is necessary for
restore of NDMP objects.
SIBF size and growth
The SIBF does not grow very big in size. For NDMP backups, the SMBF part grows proportionally to
the number of objects backed up. Approximately 3 KB are used for each backed up object.
SIBF location
The SIBF is located in the following directory:
<Data_Protector_program_data>\db40\meta (Windows Server 2008),
<Data_Protector_home>\db40\meta (other Windows systems), or
/var/opt/omni/server/db40/meta (UNIX systems).
Why should you configure the IDB?
Configuring the IDB helps you verify that you have covered all the important aspects of the IDB:
locality of the IDB components to meet high availability needs, policies that influence the IDB size and
growth, IDB backup configuration, and configuration of all IDB notifications and reports that inform
you about the IDB changes and alert conditions. Once you configure the IDB, maintenance is reduced
to a minimum, and consists of mainly acting on notifications and reports.
Note:
Additional IDB management details and configuration about the IDB can be
found in the HP Data Protector Concepts Guide, which is part of the
documentation set of Data Protector software.
