A backup is a recoverable copy of data. Disaster recovery is the people, priorities, technology and tested procedure used to restore an acceptable business service after serious disruption.<\/strong> Most businesses need both: backups supply recovery material, while the disaster-recovery plan decides what returns first, where it runs and who authorises the work.<\/p>\n

What a backup protects<\/h2>\n

A backup can protect files, databases, virtual machines, application configuration, cloud data and network-device settings. The design should identify what is included, how frequently it is copied, how long versions remain, where copies are stored, who can access them and how failures are handled.<\/p>\n

Snapshots, replication and synchronisation can support recovery but are not automatically independent backups. A deletion, encryption event or administrator mistake may replicate to another location. Understand the failure boundary of each copy.<\/p>\n

What disaster recovery adds<\/h2>\n

Disaster recovery considers the complete service: infrastructure, identity, connectivity, applications, data, suppliers, workplaces, people and communications. It defines the minimum viable service, recovery order, technical procedure, decision authority and criteria for returning to normal operation.<\/p>\n

A plan should cover credible scenarios such as loss of a server, cloud account, office, internet connection, key supplier or privileged access\u2014not only a generic \u201cdisaster\u201d.<\/p>\n

Set RPO and RTO from business impact<\/h2>\n

Recovery point objective (RPO)<\/strong> describes the maximum tolerable period of data loss. Recovery time objective (RTO)<\/strong> describes the target time for restoring an acceptable service. They are business requirements that shape technology and cost, not numbers selected by a backup product.<\/p>\n

A four-hour RPO may require data to be protected more often than once per day. A four-hour RTO may require pre-built capacity, working credentials and rehearsed procedures rather than waiting for hardware, licences and specialists after an incident.<\/p>\n

Use ACA\u2019s recovery priority planner<\/a> to rank systems from business impact, dependencies, RTO and RPO.<\/p>\n

Make backup copies independent<\/h2>\n

Keep copies across failure boundaries appropriate to the risk. This may include a separate account, provider, region, physical location or offline\/immutable tier. Restrict deletion and configuration rights, protect administrators with strong authentication and alert on changes to backup policies or retention.<\/p>\n

Encryption protects backup confidentiality, but keys and recovery credentials must remain available during an incident. Store the recovery route so an authorised person can reach it if normal identity, email or premises are unavailable.<\/p>\n

Protect the whole application, not only its files<\/h2>\n

Document databases, file storage, secrets, certificates, queues, DNS, identity, licences and third-party integrations. Use application-consistent methods where required and record the correct recovery sequence. Restoring a database from one moment and uploaded files from another can create inconsistency.<\/p>\n

Test a restore, then test the service<\/h2>\n

A restore test answers whether selected data can be recovered. A disaster-recovery exercise answers whether the business service can return within its objectives. Run both.<\/p>\n
