The Idb On The Windows Cell Manager - HP B6960-96035 Concepts Manual

• Fast and convenient restore The information stored in the IDB enables you to
quickly find the media required for a restore, and therefore makes the restore
much faster. It also offers you the convenience of being able to browse for files
and directories to be restored.
• Backup management The information stored in the IDB enables you to verify how
backups were done. You can also configure various reports using the Data
Protector reporting functionality.
• Media management The information stored in the IDB enables Data Protector to
allocate media during backup, copy, and object consolidation sessions, track
media attributes, group media in different media pools, and track media locations
in tape libraries.
IDB size and growth consideration
The IDB can grow very big and have a significant impact on backup performance
and the Cell Manager system. Therefore, the Data Protector administrator must
understand the IDB and, according to needs, decide which information to keep in
the IDB and for how long. It is the administrator's task to balance between restore
time and functionality on the one hand, and the size and growth of the IDB on the
other. Data Protector offers two key parameters to assist in balancing your needs:
logging level and catalog protection. See also

The IDB on the Windows Cell Manager

IDB location
The IDB on the Windows Cell Manager is located in the directory
Data_Protector_program_data\db40 (Windows Server 2008) or
Data_Protector_home\db40 (other Windows systems).
IDB format
The IDB on the Windows Cell Manager stores all text information in UNICODE,
double-byte format. Therefore, the IDB grows slightly faster than the IDB on the UNIX
Cell Manager, which stores information in the ASCII format.
The UNICODE format allows for full support of filenames and messages localized to
other languages.
