In a DD Boost-enabled environment, the storage node manages the backup devices, such as disk or tape devices, that are used for storing backup data. DD Boost distributes some of the deduplication processing to the backup server or storage node, helping to optimize performance. The storage node handles the communication with the backup devices and ensures that the backup data is efficiently stored.

Explanation: PowerProtect DD’s VTL functionality is compatible with major backup applications like IBM Spectrum Protect, Dell Networker, and Veritas NetBackup. These integrations enhance the data protection and recovery capabilities by supporting virtual tape operations.

When adding a second cloud unit to a DD6900, the system requires additional metadata storage to manage the data being tiered to the cloud. In this case, 180 TB of metadata storage is necessary to support the scaling of Cloud Tier and ensure efficient data management across multiple cloud units.

Explanation: The disk show state command provides the current state of each disk in an expansion shelf, allowing administrators to monitor disk health and operational status effectively, which is crucial for maintaining data integrity.

Explanation: Cloud tier migration from DDVE instances to physical PowerProtect DD systems like DD6900 is not supported, meaning data in the cloud tier cannot be directly transferred, necessitating alternative migration methods or data retrieval strategies.

Explanation: Once data is stored in the cloud tier, changing its encryption status is not possible due to data integrity and compliance constraints. Ensuring encryption settings are configured correctly before data migration is essential to secure storage in cloud environments. When data is moved to the cloud tier in a PowerProtect DD environment, the encryption status is locked in for that data. This means that once data has been stored in the cloud with encryption either enabled or disabled, this setting cannot be altered retroactively for that data. Cloud tier encryption provides secure data storage in the cloud, but any modification to encryption preferences would only apply to new data moved to the cloud after the change. This constraint ensures data consistency and integrity within the cloud storage environment.

JWTs (JSON Web Tokens): JWTs are a compact, URL-safe means of representing claims to be transferred between two parties. They are commonly used for stateless authentication in web applications, including those utilizing BoostFS.

Kerberos: Kerberos is a network authentication protocol that uses tickets to allow secure communication over a non-secure network. It is widely used in various systems, including BoostFS, to authenticate users and services.

Explanation: The gzfast compression algorithm is the default for PowerProtect DD3300, balancing compression efficiency and performance. It ensures data is compressed without compromising backup or restore speeds.

Explanation: The filesys report command provides detailed compression statistics, essential for administrators to monitor storage efficiency over time. This insight into compression ratios aids in storage optimization and management planning on PowerProtect DD systems.

Explanation: Enabling the security-officer authorization policy activates the dual authorization process, adding a layer of security by requiring approvals for certain actions. This feature is critical for environments with strict compliance and data governance requirements.
