Backup and Disaster Recovery

Translate business recovery objectives into protected backups, restores, Azure Backup, Site Recovery, multi-region architecture, failover, failback, and rehearsed disaster-recovery procedures.

How this module works

From concept to production evidence

Define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Learning outcomes

Differentiate backup, restore, replication, and DR
Set RTO and RPO
Use Azure Backup and Site Recovery
Design multi-region architecture
Run failover, failback, and DR testing

Read in order

Backup

Backup preserves durable information with explicit ownership, consistency, access, lifecycle, replication, and recovery guarantees within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Open full notes

Restore

Restore restores a safe service state while preserving evidence and reducing the chance that mitigation introduces a second failure within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

RTO

RTO provides a concrete platform capability that must be configured, secured, validated, observed, and owned throughout its lifecycle within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

RPO

RPO provides a concrete platform capability that must be configured, secured, validated, observed, and owned throughout its lifecycle within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Azure Backup

Azure Backup preserves durable information with explicit ownership, consistency, access, lifecycle, replication, and recovery guarantees within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Azure Site Recovery

Azure Site Recovery provides a concrete platform capability that must be configured, secured, validated, observed, and owned throughout its lifecycle within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Multi-region architecture

Multi-region architecture defines the major responsibilities, boundaries, and control flow that engineers use before selecting an implementation detail within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Failover

Failover restores a safe service state while preserving evidence and reducing the chance that mitigation introduces a second failure within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

Failback

Failback restores a safe service state while preserving evidence and reducing the chance that mitigation introduces a second failure within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.

DR testing

DR testing provides a concrete platform capability that must be configured, secured, validated, observed, and owned throughout its lifecycle within Backup and Disaster Recovery. It is not an isolated definition: its value appears when it supports define RTO and RPO per service, map every stateful dependency, separate backup from replication, protect recovery credentials and copies, automate orchestration, validate data and service integrity, and test failback as seriously as failover.
