Step

Action

Description

Step 1

Calculate the required data transfer rate for your backups.

Calculate the rate of transfer your system must achieve to complete a backup of all your data in the time available.

See How to calculate the required data transfer rate for your backups.

Step 2

Calculate how long it takes to back up to tape or disk

Determine what kind of tape or disk technology meets your needs.

See How to calculate the time required to back up to tape.

See About how to calculate how long it will take to back up to conventional disk storage.

See About how to calculate how long it will take to back up to deduplicate disk storage.

Step 3

Calculate the required number of tape drives

Determine how many tape drives are needed.

Step 4

Calculate the required data transfer rate for your network(s)

For backups over a network, you must move data from your client(s) to your media server(s) fast enough to finish backups within your backup window.

See How to calculate the required data transfer rate for your network(s).

Step 5

Calculate the size of your NetBackup image database

Determine how much disk space is needed to store your NetBackup image database.

See How to calculate the size of your NetBackup image database.

Step 6

Calculate the size of the NetBackup relational database (NBDB)

Determine the space that is required for NBDB.

See How to calculate the size of the NetBackup relational database (NBDB).

Step 7

Calculate the media that is needed for full and incremental backups

Determine how many tapes are needed to store and retrieve your backups.

See How to calculate the media needed for full and incremental backups.

Step 8

Calculate the size of the tape library that is needed to store your backups

Determine how many robotic library tape slots are needed to store all your backups.

See How to calculate the size of the tape library needed to store your backups.

Step 9

Design your master server

Use the previous calculations to design and configure a master server.

Step 10

Estimate the number of master servers needed

The following topic lists some considerations for estimating the number of master servers.

Step 12

Estimate the number of media servers needed

The following topic contains guidelines for estimating how many media servers are needed.

Step 13

Design your OpsCenter server

The following topic contains links to OpsCenter information.

Step 14

Review a summary of these steps

The following is a condensed overview.
