About the Deduplication Option

The Backup Exec Deduplication Option supports a data-reduction strategy by optimizing storage and network bandwidth. The Deduplication Option supports integrated deduplication at the Backup Exec server and on remote computers that have the Agent for Windows or the Agent for Linux installed. It also allows data to be deduplicated and stored on intelligent disk devices from Symantec and other vendors.

Type of deduplication

Where deduplication occurs

Benefits

Backup Exec server-side deduplication

On the Backup Exec server.

Reduces the size of backups, which reduces storage requirements.

Client-side deduplication

On the remote computer where the data is located.

Note:

The Agent for Windows is required on the remote Windows computer to perform client-side deduplication. The Agent for Linux is required on the Linux computer to perform Linux client-side deduplication.

Reduces network traffic because only unique data is sent across the network. It also reduces the backup window.

Appliance deduplication

On an intelligent disk device, such as Symantec PureDisk or a device from a third-party vendor.

Reduces the size of backups, which reduces storage requirements. It also reduces the backup window.

With a single Deduplication Option license key, you can use two types of deduplication devices.

Type of device

Description

OpenStorage device

Backup Exec uses Symantec's OpenStorage technology, which allows intelligent disk devices to integrate with Backup Exec. You can back up data to the Symantec PureDisk device and to storage devices from other vendors.

You can find a list of compatible types of storage at the following URL:

See About OpenStorage devices.

Deduplication disk storage

Deduplication disk storage provides integrated deduplication on the Backup Exec server. Deduplication disk storage is a disk-based backup folder that is located on the Backup Exec server.

See About deduplication disk storage.

In addition to reducing storage requirements and network traffic, the Deduplication Option lets you do the following:

  • Copy deduplicated data from an OpenStorage device or deduplication disk storage to tape for long-term or off-site storage.

  • Use optimized duplication, which lets you copy deduplicated data between OpenStorage devices from the same vendor and between deduplication disk storage devices.

  • Use Symantec's Granular Recovery Technology (GRT) with jobs that use deduplication devices.

  • Share OpenStorage devices and deduplication storage devices among multiple Backup Exec servers when you use the Central Admin Server Option.
