Which of the following is classified as an enterprise-level backup and recovery suite?

NetBackup is classified as an enterprise-level backup and recovery suite due to several key features that cater to large organizations and complex IT environments. It is designed to handle massive data volumes, support a wide range of platforms, and offer advanced functionalities such as deduplication, replication, and automated backup processes. This makes it suitable for enterprises that require high availability, strict compliance with data protection regulations, and effective disaster recovery strategies.

In contrast, the other options provide capabilities that may not meet the comprehensive needs of an enterprise-level infrastructure. CrashPlan focuses more on personal and small business backup solutions, emphasizing file backups and ease of use rather than the extensive enterprise features necessary for larger organizations. Acronis True Image is often considered a consumer-friendly backup solution, primarily designed for individual users and small businesses, with features that cater to personal data protection rather than large-scale enterprise requirements. Windows Backup, while useful for basic backup tasks in smaller environments or personal use, lacks the scalability, management functionalities, and robust recovery options that are critical in an enterprise setting.
