About NetBackup encryption options
NetBackup provides several methods for encrypting backups, as described in the following table.
Table: NetBackup encryption options
Option | Description |
|---|---|
Client encryption | The NetBackup client encryption option is a software-based solution that encrypts the data on the client. The data is encrypted in transit and at rest. Each client manages its own encryption keys. To enable client encryption, select the backup policy attribute. |
Tape drive encryption | With hardware-based tape drive encryption, an encrypting tape drive encrypts the data. The data is encrypted at rest only. The NetBackup Key Management Service manages the encryption keys. See the "Data at rest key management" chapter in the NetBackup Security and Encryption Guide. One method to manage the volumes for hardware-based tape encryption is to use a reserved prefix on the volume pool name. The storage device must have encrypting tape drives. The storage unit must specify the storage device that has the encrypting tape drives. The backup policy must specify the correct storage unit and volume pool. |
AdvancedDisk encryption | A plug-in in the NetBackup OpenStorage stack encrypts the data. The data is encrypted at rest only. The NetBackup Key Management Service manages the encryption keys. |
Cloud storage encryption | A plug-in in the NetBackup OpenStorage stack encrypts the data. The data is encrypted at rest only (by default, NetBackup uses SSL for read and write operations). The NetBackup Key Management Service manages the encryption keys. |
Media Server Deduplication Pool encryption | The MSDP deduplication plug-in encrypts the data. The data can be encrypted in transit and at rest or at rest only. The NetBackup deduplication plug-in manages the encryption keys. See the NetBackup Deduplication Guide. |
