Cell
Cell is a set of systems that are under the control of a Cell Manager. The cell typically represents the
systems on a site or an organizational entity, which are connected to the same LAN. Central control is
available to administer the backup and restore policies and tasks. A cell consists of a Cell Manager,
one or more Installation Servers, client systems, and devices.
Cell Manager
The main system in the cell where the essential Data Protector software is installed and from which all
backup, restore, copy, and administrative activities are managed. The GUI used for management
tasks can be located on a different system. Each cell has one Cell Manager system and it can also be
referred to as Cell Server (CS).
CDB
The Catalog Database (CDB) is a part of the IDB that contains information about backups, object
copies, restores, media management sessions, and backed up data. Depending on the selected
logging level, it also contains file names and file versions. This part of the database is always local to
the cell. This part of the database is always local.
DCBF
The Detail Catalog Binary Files (DCBF) part of the IDB stores information about file versions and
attributes. It occupies approximately 80% of the IDB. One DC binary file is created for each Data
Protector medium used for backup.
DC directory
The Detail Catalog (DC) directory consists of DC binary files, which store information about file
versions. It represents the DCBF part of the IDB, which occupies approximately 80% of the IDB. The
default DC directory is called the dcbf directory and is located in the Data_Protector_home>\db40
directory on a Windows Cell Manager and in the /var/opt/omni/server/db40 directory on a UNIX
Cell Manager. You can create more DC directories and locate them as appropriate to you. Up to 50
DC directories are supported per cell. The default maximum size of a DC directory is 4 GB.
