Commvault employs techniques like incremental backups and global deduplication to minimize the amount of data transferred during backups, thus reducing resource consumption. This approach is more efficient than full backups and ensures that only changed data is backed up, saving both time and storage space. While other options may improve performance, they don't directly address resource utilization.

Granular recovery options enable restoration at the file-level for precise recovery. This means that individual files or data elements can be recovered without restoring entire systems or volumes, offering flexibility, efficiency, and reducing the impact of data loss on operations.

The organization can configure the backup policy using the Grandfather-Father-Son (GFS) strategy, which retains monthly backups for a long-term period, aligning with the requirement of seven years retention. GFS ensures efficient management of backups over time.

Capacity planning is vital in data management as it optimizes storage utilization, ensuring that resources are efficiently used. It helps in maintaining data availability, especially during peak usage times, by allocating resources effectively. This process also aids in reducing data redundancy and improving overall data security.

Virtualization impacts Capacity Planning strategies by improving resource utilization and flexibility. It allows for better allocation of resources and reduces the need for physical hardware, leading to cost savings and operational efficiencies. However, organizations must also address challenges such as increased complexity and management overhead associated with virtualized environments. Overall, virtualization offers significant benefits but requires careful planning and management.

The choice between full, incremental, and differential backups directly impacts storage requirements. Full backups consume more storage space upfront but offer complete data recovery. Differential backups require less space than full but more than incremental backups.

AES (Advanced Encryption Standard) is a symmetric encryption algorithm used to secure sensitive data. It uses a single key for both encryption and decryption, making it efficient and widely adopted for securing data at rest and in transit.

The potential drawbacks of using tape libraries in Commvault include longer recovery times due to tape access, limited scalability for large-scale backups, and limited compatibility with modern backup technologies.

The licensing model for Commvault deployment is primarily determined by factors such as data volume, feature set required, deployment type (on-premises or cloud), and the number of users accessing the system. Understanding these factors helps in choosing the most suitable licensing option for specific organizational needs.

The primary role of Commvault's core functionalities is to ensure data protection and availability. By offering reliable data backup, recovery, and disaster recovery solutions, Commvault helps organizations safeguard their critical data assets and ensure business continuity. This role is crucial in today's digital landscape, where data is a cornerstone of business operations and success.
