Planning for storage of encrypted data
Determine whether your company requires stored data to be encrypted, and choose the option that best suits your needs.
If your company requires the data in storage pools to be encrypted, then you have the option of using IBM Spectrum Protect encryption, or an external device such as tape for encryption.
If you choose IBM Spectrum Protect to encrypt the data, extra computing resources are required at the client that might affect the performance of backup and restore processes.
