is that it can require more administrative work or might even require a separate

administrator for each cell.

• Size of each cell

The size of a Data Protector cell affects backup performance and the ability to

manage the cell. The recommended maximum size for a Data Protector cell is

100 client systems. Cells with more than 200 client systems are less manageable.

• Network considerations

All client systems of a cell should be on the same LAN for maximum performance.

For more information about other network considerations such as your network

configuration, see the sections that follow.

• Geographical location

If the client systems you want to back up are geographically dispersed, it may

be difficult to manage them from a single cell and there may be networking

problems between the client systems. Additionally, the security of data may be

an issue.

• Time Zones

Each cell should be within one time zone.

• Security of data

Data Protector provides cell level based security. All Data Protector administrative

work is done in the context of a single cell: media, backup devices, and backed

up data belong to one cell. Note that Data Protector lets you share devices or

move media between cells, so physical access to media must be limited to

authorized personnel.

• Mixed environments

Data Protector allows you to back up client systems of diverse platforms in a single

cell. However, it may be convenient to group client systems in a cell based on

the platforms. For example, you may have one cell with the Windows client

systems and one with the UNIX client systems. This is especially useful if you have

separate administrators and policies for the UNIX and Windows environments.

• Departments and sites

You can group each department or site in a separate cell. For example, you may

have one cell for the accounting, one for the IT, and one for the manufacturing

department. Even if you choose to have several cells, Data Protector allows you

to easily configure common policies among the cells.
