Automated Backups in Cloud Questions and Answers for Viva

Answer-1: Automated backups are scheduled, system-managed copies of data that occur without manual intervention, ensuring data protection in cloud environments.

Answer-2: They ensure data availability, reduce human error, enable disaster recovery, and help meet compliance requirements.

Answer-3: AWS Backup, Azure Backup, Google Cloud Backup, and third-party tools like Veeam and Druva.

Answer-4: Automated backups run on schedules without manual triggers, whereas manual backups require human initiation.

Answer-5: Incremental backup saves only the data changed since the last backup, reducing storage and time.

Answer-6: Full backups copy all data; incremental backups copy only changed data since the last backup.

Answer-7: Snapshots capture the state of a system or volume at a point in time, enabling fast, automated backups.

Answer-8: Object storage like AWS S3, Azure Blob Storage, and Google Cloud Storage are common for backups.

Answer-9: Using AWS Backup service or AWS Lambda with CloudWatch events to trigger backups.

Answer-10: Retention policies define how long backups are stored before automatic deletion to manage costs and compliance.

Answer-11: Yes, backups should be encrypted at rest and in transit to protect sensitive data.

Answer-12: By using snapshot-based backups, application-aware backups, or quiescing techniques during backup.

Answer-13: Cross-region backup stores copies of data in geographically separate locations to increase disaster resilience.

Answer-14: It ensures data is regularly saved and can be restored quickly to minimize downtime after failures.

Answer-15: Backup is for recovery of recent data, while archiving is long-term storage for infrequently accessed data.

Answer-16: Cloud-native databases like AWS RDS support automated snapshots and backups managed by the service.

Answer-17: Managing costs, ensuring backup frequency matches RPO, and verifying backup integrity.

Answer-18: It removes manual backup tasks, enabling consistent and reliable backup without human intervention.

Answer-19: RPO defines the maximum acceptable amount of data loss measured in time.

Answer-20: RTO defines the maximum acceptable downtime to restore data and resume operations.

Answer-21: Yes, scheduling, retention, encryption, and backup scope can be customized in most cloud backup services.

Answer-22: The backup window is the time period allocated to perform backups without impacting performance.

Answer-23: Charges are based on storage used, backup frequency, data transfer, and retrieval operations.

Answer-24: Through dashboards, alerts, and logs provided by cloud backup services.

Answer-25: Agent-based requires software on target systems; agentless uses APIs or snapshots without installing agents.

Answer-26: It centralizes and automates backup scheduling, retention, and compliance across AWS services.

Answer-27: An immutable backup cannot be altered or deleted for a specified retention period, enhancing data protection.

Answer-28: By ensuring data is backed up regularly, stored securely, and retained according to regulations.

Answer-29: Yes, some backup solutions provide application-aware backups enabling point-in-time restores.

Answer-30: They automate infrastructure provisioning including backup configurations for consistency and repeatability.

Answer-31: They reduce storage needs by backing up only changed data, lowering overall costs.

Answer-32: A secure storage location specifically designed to hold backup data with access controls.

Answer-33: Versioning keeps multiple copies of backups over time, allowing recovery from different points.

Answer-34: APIs allow integration, triggering, and management of backups programmatically.

Answer-35: They often use database snapshots or transaction logs for consistent point-in-time recovery.

Answer-36: Backup is periodic copying of data for recovery; replication continuously copies data to another location for high availability.

Answer-37: Yes, using cross-cloud backup tools or cloud-agnostic backup solutions.

Answer-38: By using checksums, verification processes, and automated testing of backup restorations.

Answer-39: Proper key management ensures encrypted backups remain secure and recoverable.

Answer-40: By scheduling backups during off-peak hours and using efficient snapshot or incremental methods.

Answer-41: Restoring data to a specific moment, useful for recovering from data corruption or accidental changes.

Answer-42: By leveraging incremental backups, parallel processing, and scalable cloud storage.

Answer-43: Regularly perform test restores to verify backup validity and recovery procedures.

Answer-44: By storing backup copies across multiple data centers or regions.

Answer-45: Yes, VM snapshots and backups are common automated backup use cases.

Answer-46: They automate transition of backups between storage classes and eventual deletion to optimize costs.

Answer-47: They alert admins about backup success, failures, or anomalies for timely intervention.

Answer-48: By eliminating duplicate data blocks during backups to reduce storage consumption.

Answer-49: SLAs define guaranteed backup availability, performance, and recovery time objectives.

Answer-50: They provide the foundational data copies needed for restoring systems after a disaster.
