Configuring encryption for MSDP local storage volume

Encrypting a key with another key is called envelop encryption. MSDP uses an envelope encryption. It generates a random data encryption key and uses that key to encrypt MSDP segment data, and then uses a KMS key to encrypt the data encryption key.

All systems do not have KMS setup, therefore, the data encryption and KMS are configured separately. This topic describes how to enable the data encryption.

More information is available on how to configure and to use KMS.

See About MSDP Encryption using NetBackup Key Management Server service.

For MSDP initial setup, you can use NetBackup web UI to configure encryption. Use the following steps manually to enable encryption for the existing systems. Once enabled, all data to the MSDP server local disk volume including NetBackup media servers, servers in opt-dup, servers in AIR, and client direct hosts is encrypted. You are not required to configure encryption at any other places.

Note:

The following steps are for MSDP local disk volume only. For MSDP cloud volume encryption, see the following topic.

See Configuring encryption for MSDP cloud storage volumes.

To configure backup encryption for MSDP local storage volume

On the storage server, open the contentrouter.cfg file in a text editor; it resides in the following directory:
- (UNIX) storage_path/etc/puredisk
- (Windows) storage_path\etc\puredisk
Add encrypt to the ServerOptions line of the file. For example:
ServerOptions=fast,verify_data_read,encrypt
Encryption is enabled for all the data that is stored on the server, which includes the MSDP storage server, the MSDP load-balancing servers, and the NetBackup Client Direct deduplication clients.
Restart the MSDP services.

Note:

Encryption configuration using the pd.conf file needs changes in NetBackup media servers or clients, and its use is deprecated.
