What is an incremental backup?
- A backup of metadata only
- A backup of only changed data
- A backup of selected files only
- A backup that includes all data every time
An incremental backup is a type of backup that only includes data that has changed since the last backup, reducing storage space and backup time compared to full backups.
Recovery strategies should align with __________ to meet organizational objectives.
- Business requirements
- Compliance regulations
- Customer preferences
- IT infrastructure
Recovery strategies should align with business requirements to meet organizational objectives. This alignment ensures that the recovery plan addresses the specific needs and priorities of the business, including data recovery priorities, resource allocation, and minimizing disruptions to operations.
During data transfer, secure protocols help prevent __________ and ensure __________.
- Data breaches; data availability
- Data loss; data integrity
- Network congestion; data redundancy
- Unauthorized access; data confidentiality
Secure protocols like TLS and SSH help prevent unauthorized access, ensuring data confidentiality, and they also maintain data integrity, preventing data tampering during transmission.
Commvault's audit logging feature assists organizations in maintaining __________ with industry standards and regulations.
- Backup and recovery efficiency
- Data availability and reliability
- Data governance and compliance
- Network infrastructure and scalability
Commvault's audit logging feature helps organizations maintain data governance and compliance with industry standards and regulations by providing detailed logs of data access and changes, aiding in audits, and ensuring adherence to data policies and regulations.
Deduplication storage pools in Commvault help in reducing __________ and __________.
- Complexity, Backup frequency
- Costs, Data redundancy
- Network bandwidth, Data loss
- Storage space, Backup time
Deduplication storage pools in Commvault are designed to reduce costs by eliminating data redundancy and optimizing storage space. When data is deduplicated, redundant copies are removed, which directly impacts the storage space required for backups. This reduction in data redundancy leads to efficient use of storage resources and ultimately helps in reducing costs associated with storage infrastructure and backup operations.
Scenario: A large enterprise is experiencing significant growth in data volume. How can Commvault's deduplication storage pools help in managing this growth effectively?
- Improve backup speed and reduce storage costs
- Ensure data integrity and enhance disaster recovery capabilities
- Optimize storage utilization and simplify data management
- Enhance data security and compliance
Deduplication storage pools in Commvault help in managing data growth effectively by optimizing storage utilization. Deduplication reduces redundant data, thus saving storage space and simplifying data management. This feature does not directly affect backup speed, data integrity, disaster recovery, data security, or compliance. Therefore, option 3 is the correct choice.
A large corporation needs to ensure minimal data loss in case of a disaster. Which backup strategy would you recommend, and why?
- Differential Backup: Backs up all changes since the last full backup, allowing for faster restores but potentially longer backup times.
- Full Backup: Backs up all data every time, ensuring complete recovery but consuming more storage.
- Incremental Backup: Backs up only changed data since the last backup, reducing backup time and storage needs.
- Synthetic Full Backup: Combines incremental backups into a full backup image, balancing between speed and storage efficiency.
Synthetic Full Backup combines the advantages of incremental backups (efficiency) and full backups (completeness), making it ideal for minimal data loss scenarios. It reduces backup time and storage requirements while ensuring comprehensive recovery capabilities. This strategy is well-suited for large corporations where data loss must be minimized without compromising on recovery speed or storage efficiency.
What are the best practices for key management in data encryption?
- Rotate keys infrequently
- Share keys openly with authorized users
- Store keys with encrypted data
- Use strong, randomly generated keys
Key management in data encryption involves storing keys separately from encrypted data, using strong and randomly generated keys, restricting key access to authorized users, and regularly rotating keys to enhance security. Storing keys with encrypted data or sharing keys openly can lead to security vulnerabilities. Following best practices in key management is essential for maintaining the confidentiality and integrity of encrypted data.
Scenario: An organization requires real-time alerts for specific events occurring within its backup environment. How can Commvault's reporting options fulfill this need?
- Configure threshold-based alerts for critical backup events such as job failures and storage capacity breaches.
- Leverage machine learning algorithms to automatically detect and send alerts for anomalous backup activities.
- Set up manual triggers for generating alerts based on predefined conditions in the backup environment.
- Use built-in templates for common alert scenarios and customize them according to organizational requirements.
Commvault's reporting options enable organizations to set up real-time alerts for critical backup events, ensuring proactive identification and resolution of issues to maintain data availability and integrity.
How do automation and scripting features benefit Commvault users?
- Enhance disaster recovery procedures
- Improve data retention policies
- Increase data accessibility
- Reduce manual errors
Automation and scripting features in Commvault benefit users by reducing manual errors, ensuring data integrity, and optimizing data management processes. This results in increased efficiency and improved outcomes for backup and recovery tasks.
