Best Practices For Data Backup And Recovery

The recent news on AWS center in the Middle East going down because of the war made me relive my experience decades ago! I once helped build what we proudly called a best-in-class disaster recovery architecture. We did everything right—on paper. ✔️ Business Impact Analysis done ✔️ RTO & RPO agreed with stakeholders ✔️ Sophisticated tools deployed ✔️ DR site fully provisioned We were confident. Almost too confident and then came the day that tested everything ! A dual power supply failure hit our primary data center. Within minutes, 300+ servers went down abruptly. What followed was worse than downtime: Critical application databases got corrupted AND THEN The DR site also got corrupted ! Real-time transactions came to a complete standstill. With every passing hour, we lost millions of dollars in revenue. In that moment, all our architecture diagrams, tools, and planning meant one thing: NOTHING —because the system didn’t recover !!! What this experience taught me: 1) Testing isn’t real until it’s brutal Table-top simulations give comfort. Full-scale failover drills expose truth. Test like it’s already failing: -Simulate real load -Introduce chaos scenarios -Assume components will fail unexpectedly 2) DR is not a technology problem—it’s a systems problem We focused heavily on tools. We underestimated dependencies. Ensure: -End-to-end recovery (infra + app + data integrity) -Isolation between primary and DR (to avoid cascade failures) -Backup validation, not just backup completion 3) Communication is your real recovery engine In crisis, confusion spreads faster than outages. Build: -Clear SOPs for business continuity -Pre-defined escalation paths -Regular cross-team drills (not just IT—include business teams) 4) Leadership presence changes outcomes War rooms are intense. Fatigue, panic, and noise creep in. As a tech leader: -Your presence brings calm -Your clarity drives prioritization -Your energy keeps teams going Sometimes, leadership is less about answers… and more about Stability 5) Assume your DR will fail—and design for that This was the hardest lesson. Build layers: - Immutable backups - Offline recovery options -“Last resort” recovery playbooks Because resilience is not about one backup plan. It’s about what happens when that backup plan fails... Have you ever seen a #DR plan fail in real life? How often do you run full-scale disaster recovery drills? What’s the one thing most organizations still get wrong about resilience? Curious to hear real experiences—those are always more valuable than frameworks. #DR #disasterrecovery #drill #test #BCP #leadership #technology #resilience

𝗧𝗲𝘀𝘁𝗶𝗻𝗴 𝗮𝗻𝗱 𝘃𝗮𝗹𝗶𝗱𝗮𝘁𝗶𝗻𝗴 𝗢𝗧 𝗯𝗮𝗰𝗸𝘂𝗽𝘀 A backup you have never restored is an assumption, not a recovery capability. For critical OT systems: ▪️ Test restores regularly Use non-production hardware or an approved test environment. Set the frequency according to system criticality and rate of change. ▪️ Validate the complete recovery bundle Confirm controller logic, configurations, firmware, engineering files, licences, communication settings and supporting tools. ▪️ Measure the recovery time A successful restore is not enough if it exceeds the operational recovery time objective. ▪️ Close every gap Record missing files, version conflicts, failed steps and unclear ownership. Fix them before the next exercise. 𝗚𝗹𝗼𝗯𝗮𝗹 𝗴𝘂𝗶𝗱𝗮𝗻𝗰𝗲 This approach aligns with: ✓ NIST SP 800-82 Rev. 3, which recommends testing restoration from backup data for OT environments. ✓ ISO 22301, which focuses on preparedness, continuity and effective recovery from disruptive incidents. ✓ ISA/IEC 62443, which provides security-program requirements for industrial automation and control systems. 𝗞𝗲𝘆 𝘁𝗮𝗸𝗲𝗮𝘄𝗮𝘆 Backup strategy is a document. Backup validation is a habit. Only one of them helps at the exigency. #OTSecurity #BackupAndRecovery #IEC62443 #NIST #BusinessContinuity #IndustrialCybersecurity

🔥 When a data center fire wipes out 858 TB of government data — and there was no backup 😳 South Korea’s government is now grappling with what may be irreversible data loss after a battery fire at a Daejeon facility destroyed the “G-Drive” storage system, reportedly with no backups in place. (https://lnkd.in/dP9SaNJq) This is a painful reminder: physical infrastructure failures are inevitable. The question is—how well can our systems survive? What public cloud (or hybrid) resilience looks like: ✅Store data across independent availability zones/regions so that one failure doesn’t take everything down ✅Use write-once read many (WORM) or snapshot versioning to protect against accidental or malicious deletions ✅Automate DR failover drills, readiness, and verified rehearsals ✅Use declarative templates so infrastructure can be re-created in another region quickly ✅Mirror critical systems across multiple cloud providers ✅Regular hash validation, checksums, and audit pipelines to detect silent corruption 🛡️ Call to Action (for government / regulated sectors especially) ▪️Mandate minimum resilience SLAs for cloud providers used in public sector deployments. ▪️Evaluate your current architecture: Where are single points of failure? ▪️Run regular “disaster simulations” — test your recovery plans under real conditions. ▪️Adopt zero trust and data immutability paradigms — in addition to perimeter, protect the data itself. ▪️Skip complexity unless necessary — simple versioning + cross-region replication often provides most of the protection you need. We can’t prevent all disasters, but we can build systems that survive them. 👍 Like / Share if you believe resilience should be non-negotiable 🔁 Comment your DR strategies or lessons learned Disclaimer: AI tools were used to research and edit this post; however, all opinions are my own.

You likely know having a backup is essential—but it’s not enough. A backup that hasn't been validated could leave your business vulnerable when disaster strikes. Whether it's a ransomware attack, hardware failure, or accidental deletion, relying on untested backups can lead to incomplete or corrupted data recovery. Periodically restore data from backups to verify their integrity. Don’t assume they work—test them! Implement the 3-2-1 rule: 3 copies of your data, on 2 different media types, with 1 stored off-site. Use automated tools to monitor your backup processes and receive alerts for any failed jobs or inconsistencies. Ensure backups are encrypted, both in transit and at rest, to protect against unauthorized access. A validated backup system ensures you're not just backing up data, but backing up reliably. Thus, giving you peace of mind when you need it the most. If the backup does not have validated recovery, it is not a backup – it is, at best, a hope! - Keith Palmgren Don’t wait for a crisis to find out your backup plan wasn’t enough!

The backup worked. The restore failed. I have spent more than 20 years working on healthcare systems. That experience taught me to trust measured performance, not green status emails. Backups can run every night. Status emails can confirm success. Compliance audits can pass. None of that proves a critical healthcare system can be restored within the time patient care requires. When a patient scheduling system goes down, teams may discover: → The database was backed up, but key configuration settings were not. → Required credentials are unavailable. → System dependencies must restart in a specific order. → A two-hour recovery estimate becomes an all-day event. → Scheduling, visit history, and billing slow down or stop. Blaming IT misses the larger issue. A reliable restore requires coordination across IT, operations, clinical teams, compliance, and leadership. The test gets delayed because taking a working system offline feels risky. Meanwhile, servers are upgraded. Access rules change. Encryption keys rotate. Dependencies shift. A restore process that worked two years ago may not work today. A green backup report proves that a job ran. A restore test proves that care can resume. The attached checklist covers four practices every healthcare organization should use: 1️⃣ Test a complete restore 2️⃣ Measure the actual recovery time 3️⃣ Assign one accountable owner 4️⃣ Document the recovery sequence When did your team last complete a realistic restore of a critical healthcare system: last quarter, last year, or never? - ♻️ Repost this for your next risk or governance meeting. ► Follow Wylie Blanchard for more insights on uptime, security, and IT governance.

Dear IT Auditors, Testing Backups and Disaster Recovery Backups fail silently. Leaders assume recovery works until a real outage proves otherwise. Your audit removes that uncertainty. You test readiness under pressure, not policy intent. You focus on recoverability, ownership, and execution. 📌 Identify critical systems and data You work with leadership to define what must be recovered first. You include customer-facing platforms, financial systems, and AI workloads. You confirm recovery priorities align with business impact. 📌 Review backup scope and frequency You verify all critical systems are backed up. You test backup schedules against data change rates. You flag systems with gaps or infrequent backups. 📌 Test backup integrity You validate that backups complete successfully. You review error logs. You confirm that encryption protects backup data. You identify backups stored in the same risk zone as production. 📌 Perform restore testing You select samples for restoration. You observe the process. You confirm the accuracy and usability of the data after restoration. You highlight failures that teams never tested. 📌 Evaluate recovery time and recovery point objectives You compare test results to stated RTOs and RPOs. You quantify gaps. You demonstrate to leaders how long systems remain unavailable during real events. 📌 Review access and segregation controls You test who can access backups. You confirm limited privileges. You flag shared credentials or unmanaged access. 📌 Inspect disaster recovery plans You review documentation for clarity and ownership. You confirm plans reflect the current architecture. You test if teams know their roles. 📌 Analyze recent incidents You review outages and near misses. You trace outcomes to backup or recovery weaknesses. You use real events to prove risk. 📌 Close with resilience-focused reporting You show leaders where recovery works and where it breaks. You prioritize fixes based on business impact. You help leadership invest with confidence. #ITAudit #DisasterRecovery #CyberVerge #CyberYard #BackupTesting #BusinessContinuity #CybersecurityAudit #InternalAudit #GRC #CloudResilience #RiskManagement #ITGovernance #TechLeadership

Humans suck at disaster recovery. So let's remove them. Humans REALLY suck at 3am waking up to a bunch of pages. That's when the "oops deleted the prod database" in a panic frenzie tends to happen. I know a few people following me know deep down the sheer terror of walking into a datacenter and hearing deafening silence. Not many thoughts can make your hair stand on end quite like that. This is why ephemerial infrastructure patterns are so important. I know a bunch of people that have a fire drill pattern for back up and restore. Fire drills are good because they prepare you BUT there is a better way - remove the human altogether. Imagine a 100% reduction in labor for DR and recovery testing. Seems crazy right? Someone close to me once called GitOps "forward-ups" instead of "backups" because you pay the cost of recovery up front. Right now - during the working day is when i'm ready to think about hard problems. Not when I was abruptly yanked into consiousness by a loud noise on my phone. Not when everyone is in a 'war-room' pointing fingers and yelling. So if i play it smart - I can declare to machines what a good working end state looks like. That way I have a "true north" or target. If I can take this true north and give it to computer programs to 'true up' - the computer program will do the process of fixing the issues for me. A common DR test I see is to take a test environment down and test a restore into it. Because of stateful dependancies - this may or may not reflect what production looks like. It's hard to say... There are a lot of unknowns in this pattern but I guess it's better than nothing.... (until your restore fails - then all that time was wasted) But with a clear IaC pattern you have a hard contract of code with your infrastructure. Rather then trying to move back time on your infrastructure - you can stamp out clones of it. With IaC, auto-reconciliation loops and useful healthchecks you can reduce the intervention of humans almost exclusively (unless you are having a really really really bad day). A good DR strategy actually follows what Devs do for integration testing. In a pattern (say weekly) - you spin up a new environment. that is 1:1 to your production environment. Run a series of tests. after the checks pass put a green checkmark saying we ran and destroy the environment. This process can be 100% hands off if done correctly. Else, notify the admin of the problem. This allows for proactive response and reduces notification toil. So what is the process of recovery? Do a manual run of another pipeline that deploys prod... Prod now represents EXACTLY what you defined in your hard code contract. Tired humans are the Inverse of reliable infrastructure!

So, you've got your backups all set up? You've joined the elite club of responsible data guardians. But wait—have you ever actually tried restoring those backups? Or are they just sitting there like unread terms and conditions? Let me paint you a picture: Imagine a disaster strikes—let's call it "The Great Server Meltdown of Monday Morning" (because disasters love Mondays). You spring into action, ready to restore your data and save the day. You click "Restore," and then... Estimated time remaining: 7 days, 14 hours, 27 minutes. Cue the awkward coffee breaks and frantic Googling of "How to tell your boss the data will be back next week." Here's why actually testing your backups is crucial (and might save you from becoming a meme): The Illusion of Security: Just because your data is backing up doesn't mean it's coming back quickly—or at all. Testing ensures that your backups aren't just digital paperweights. Time Warp Reality Check: Downloading terabytes of data isn't like downloading a movie on Netflix. It's more like trying to empty a swimming pool with a spoon. Over the internet. While it's raining. Bandwidth Bottlenecks: In a real disaster, everyone's scrambling. Network speeds can crawl slower than a traffic jam on a Friday afternoon. Avoiding the "Uh-Oh" Moment: Discovering that your backup is corrupt after a disaster is like realizing you've locked your keys in the car—with the engine running. So, what's the game plan? Regular Restore Drills: Think of it as a fire drill but for your data. Schedule regular tests to restore your backups so you're not navigating unfamiliar territory when it counts. Know Your Restore Time: Calculate how long it would actually take to get your systems back online. Factor in data size, network speed, and any potential hiccups. Prioritze your data: Do a Business Impact Analysis to understand what processes and data are critical for your business and make them a priority. Know your MTD! Optimize Your Backups: Use incremental backups, data deduplication, or even physical storage solutions to reduce restore times. Sometimes, old-school methods like shipping a hard drive can be faster! Document Everything: Keep a clear, step-by-step recovery plan. In a crisis, your future self (and your team) will thank you. Remember, backups are like parachutes—if they don't work when you need them, you don't get a second chance. Stay prepared, stay tested, and may your backups restore swiftly! #DataRecovery #Backups #AlwaysBePrepared

Are Your Backups Ready for the Worst? 🚨 Matt Johnson and I are teaming up to tackle this head-on. Together, we’re helping businesses move beyond blind trust to real backup reliability. In business, "Our backups are good" isn't enough. Backups are your safety net, but unless you're actively testing, monitoring, and verifying them, you could be left unprotected when disaster strikes. 📊 Here’s a reality check: One client believed their backups were running smoothly until they weren’t. When a system failure hit, the backups failed to restore because they hadn’t been properly tested. The result? Hours of downtime and significant data recovery costs. 💡 How to make sure your backups work when you need them most: 1️⃣ Test regularly. A backup that hasn’t been tested might as well not exist. 2️⃣ Use advanced monitoring tools to ensure backups are running successfully. 3️⃣ Understand your tools. Don’t just set it and forget it know what alerts mean and how to act on them. 🔑 Pro Tip: Ask your team to show you the process don’t rely on verbal assurances. Clear documentation and regular reviews are critical to ensuring you’re truly protected. 👉 When was the last time you tested your backups? Let’s talk about creating a system you can trust.
