About the Deduplication feature
The Backup Exec Deduplication feature supports a data-reduction strategy by optimizing storage and network bandwidth. The Deduplication feature 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 Veritas and other vendors.

Table: Types of deduplication
| 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. | Reduces network traffic because only unique data is sent across the network. It also reduces the backup window. |
| Note: The Agent for Windows is required on the remote Windows computer to perform Windows client-side deduplication. The Agent for Linux is required on the Linux computer to perform Linux client-side deduplication. | ||
| Appliance deduplication | On an intelligent disk device, such as Veritas 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 feature license key, you can use two types of deduplication devices.
Table: Types of deduplication devices that work with the Deduplication feature
| Type of device | Description |
|---|---|
| OpenStorage device | Backup Exec uses Veritas's OpenStorage technology, which allows intelligent disk devices to integrate with Backup Exec. You can back up data to the Veritas PureDisk device and to storage devices from other vendors. |
| You can find a list of compatible types of storage at the following URL: | |

| See Configuring an OpenStorage device . | |
| 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. |
In addition to reducing storage requirements and network traffic, the Deduplication feature 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 Veritas'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 feature.
