The Backup Wrap-Up

W. Curtis Preston (Mr. Backup)

Formerly known as "Restore it All," The Backup Wrap-up podcast turns unappreciated backup admins into cyber recovery heroes. After a brief analysis of backup-related news, each episode dives deep into one topic that you can use to better protect your organization from data loss, be it from accidents, disasters, or ransomware.   The Backup Wrap-up is hosted by W. Curtis Preston (Mr. Backup) and his co-host Prasanna Malaiyandi. Curtis' passion for backups began over 30 years ago when his employer, a $35B bank, lost its purchasing database – and the backups he was in charge of were worthless. After miraculously not being fired, he resolved to learn everything he could about a topic most people try to get away from.  His co-host, Prasanna, saw similar tragedies from the vendor side of the house and also wanted to do whatever he could to stop that from happening to others. A particular focus lately has been the scourge of ransomware that is plaguing IT organizations across the globe.  That's why in addition to backup and disaster recovery, we also touch on information security techniques you can use to protect your backup systems from ransomware.  If you'd like to go from being unappreciated to being a cyber recovery hero, this is the podcast for you.

    Ransomware Response Checklist: Prevent It, Slow It, Survive It

    This episode is built around a ransomware response checklist — a three-part Reddit series by a security specialist who goes by snorkel42, breaking down exactly how to prevent, contain, and recover from a ransomware attack. This is an encore episode, and it's back not just because a lot of people downloaded it originally, but because so many of you listened all the way through — some of you more than once. That kind of engagement told us this one was worth bringing back. Curtis Preston and Prasanna Malaiyandi dig into snorkel42's series, which breaks the whole problem into three parts: how to stop ransomware from getting in, how to slow it down if it does, and what to actually do once you've been hit. Curtis and Prasanna go section by section — covering phishing and dropper prevention, application whitelisting, blocking lateral movement between servers, locking down RDP and SSH, honeypot files for catching intruders in the act, and building a real incident response plan before you ever need one. They also get into the messier parts most people don't talk about — what it's actually like to negotiate for a decryption key, why getting your data back isn't the end of the story, and why a ransomware attack is nothing like a normal disaster recovery scenario. Along the way, Curtis makes the case that most organizations already have the gaps this attacker needs — and that fixing them now is a lot cheaper than fixing them after the fact. Whether you're building your first incident response plan or just want to stress-test the one you've already got, this episode gives you a practical, section-by-section framework to work from.

    How to Protect Backups from Ransomware (Encore)

    How to protect backups from ransomware starts with a hard truth: attackers aren't just encrypting your data anymore, they're stealing it first — and no backup system on earth undoes an exfiltration. In this encore episode of The Backup Wrap-Up, Curtis and Prasanna dig into what real immutability looks like versus the marketing version, why root access quietly undermines most "immutable" storage claims, the difference between virtual and true physical air gaps, and the exact questions you should be firing at your backup vendor before you trust them with your last line of defense. This one's an encore for a reason — it was one of the most listened-to episodes in the show's history, with listeners sticking around for the full runtime and then some. That's the kind of signal that tells you it's worth a second run. Along the way, they cover S3 object lock and what actually happens if your account gets deleted or your credit card stops working, why compromised admin credentials are involved in the majority of attacks and what your vendor should be able to undo, and why bit rot — rare, but nasty when it's silent — still belongs on your checklist. If you manage backup or DR for a living, or you're just trying to figure out whether your current setup would actually hold up, this episode gives you a concrete list of questions to ask and red flags to watch for. Chapters: 00:00 – Cold Open: Ransomware Is After Your Backups 01:19 – Welcome & Banter 05:50 – Topic Setup: Protecting Backups from Ransomware 07:36 – The Extortion & Exfiltration Playbook 15:25 – What Is an Air Gap? 18:22 – Virtual Air Gaps 27:57 – Real (Physical) Air Gaps 28:12 – What Is Immutability, Really? 29:23 – Bit Rot 30:42 – Root Access & the Limits of Immutability 32:51 – S3 Object Lock 40:20 – Questions to Ask Your Backup Vendor 42:31 – What Happens If You Delete Your Account? 44:29 – Compromised Credentials & Worst-Case Scenarios 46:41 – Final Thoughts

    What Is Data Deduplication? (Encore)

    What is data deduplication, and why does Curtis call it the single most important development in backup over the last 30 years? In this encore episode, W. Curtis Preston and Prasanna Malaiyandi break down exactly how dedupe works, why it's not the same as compression, and why the fine print of your dedupe domain determines how much storage you actually save. This episode originally aired as part of the Backup to Basics series, and it's back because listeners couldn't get enough of it — not just downloads, but people who stuck around for the whole conversation, some more than once. That says something, because this isn't a surface-level explainer. Curtis and Prasanna get into fingerprints, dedupe indexes, and the real-world tradeoffs between file-level and block-level dedupe. You'll hear why Curtis argues that file-level dedupe isn't "real" dedupe at all, just single-instance storage wearing a costume. Then the conversation shifts to the split that shapes entire product categories: source-side dedupe versus target-side dedupe. Curtis walks through why source dedupe requires you to essentially replace your backup software, while target dedupe lets you bolt an appliance onto whatever you're already running. Prasanna pushes back on some of the assumptions along the way, which is exactly the kind of back-and-forth that made this episode stick with listeners the first time around. By the end, they even get into hybrid dedupe, a concept that splits the difference and confuses almost everyone the first time they hear about it. If you've ever wondered why your backup storage doesn't need to be 30 or 40 times the size of your production data, or you just want to finally understand what your backup vendor means when they throw around terms like "dedupe ratio," this is the episode that clears it up. Chapters: 00:00 – Intro 08:10 – What Is Data Deduplication? 12:24 – Dedupe vs. Compression 16:13 – Fingerprints and the Dedupe Index 16:52 – What's a Dedupe Domain? 19:48 – Is File-Level Dedupe Really Dedupe? 21:53 – Source Dedupe vs. Target Dedupe 28:20 – What Is Hybrid Dedupe?

    The REDCap Attack that Phishing-Resistant MFA Could Have Stopped

    Phishing-resistant MFA could have stopped a Chinese state-sponsored threat actor from spending over a year inside North American academic and medical research networks — and we're going to tell you exactly how it happened and what you need to do about it. A group called UNC5608, tracked by Google's Threat Intelligence Group (GTIG), exploited a vulnerability unique to REDCap — a research data platform that allows multiple software versions to run simultaneously. They got in via stolen admin credentials, planted custom malware called Infinite.red directly into REDCap's upgrade process, harvested credentials for over a year, then used those credentials to log into Google Workspace as a domain admin and create fake compliance rules to silently forward sensitive research emails — military strategy, geostrategic policy, advanced tech, specific pathogens — straight to Gmail accounts they controlled. And nobody noticed for a very long time. Prasanna and I break down the full attack chain, then walk through every prevention layer that could have stopped it: inventory management, patching, password hygiene, SSO, phishing-resistant MFA, passkeys, DBSC, context-aware access, compliance rule monitoring, credential separation across security domains, and logging. We also get into what backups can and can't do for you in a long-dwell-time attack like this — and why infrastructure-as-code and truly immutable golden images matter more than you might think. If you're running any kind of research platform, academic institution, or medical network — or honestly any organization that uses Google Workspace — this one's for you. Chapters: 00:00 — Intro: The attack that phishing-resistant MFA could have stopped 01:03 — Show intro & woodworking banter 03:26 — What is a living-off-the-land attack? 04:02 — Who is UNC5608 and who did they target? 05:08 — How REDCap's multi-version design was exploited 06:11 — Infinite.red malware and credential harvesting 09:01 — Google Workspace infiltration via fake compliance rules 10:18 — The keywords they were stealing: pathogens, military strategy, and more 11:50 — What could the victims have done differently? 12:42 — Inventory management, patching, and legacy version removal 14:00 — Why you can't trust application-level authentication alone — use SSO 15:18 — Phishing-resistant MFA and why it matters 16:00 — Passkeys, FIDO, and why there are zero known attacks against them 17:57 — Device-bound session credentials (DBSC) and context-aware access 19:38 — Monitor your compliance rules — have a compliance rule for the compliance rule 20:40 — Credential separation across security domains 23:00 — Get some logging — XDR, SIEM, and catching exfiltration in progress 24:00 — What can backups actually do in a long-dwell-time attack? 27:00 — Infrastructure-as-code and the right cyber recovery approach 28:58 — Protecting your golden images with immutable storage 31:59 — Wrap-up

    California Election Fraud? (Pt 2)

    California election fraud claims are flooding social media — and most of them fall apart under basic scrutiny. In this follow-up episode, longtime San Diego County poll worker W. Curtis Preston tackles the wave of viral fraud allegations head-on, with sources so you can check his work yourself. Topics covered: the LA mayoral race "statistically impossible" surge for Nithya Raman, the AP reporting error that got blamed on fraud, claims that Spencer Pratt voters were having ballots rejected for signatures, the "gym membership card" voter ID myth, the Skid Row "paid to vote" controversy, and yes — the one claim that turned out to be true (a woman who actually did register her dog to vote). If you've seen these claims and wondered whether there's anything to them, this episode walks through the actual data, the actual law, and the actual outcomes — no spin, just the facts from someone counting the votes. Here are some sources: Los Angeles 2026 Mayor primary results: https://results.lavote.gov/#year=2026&election=4338 Donald Trump got 27% of City of LA vote in 2024: https://xtown.la/2024/12/16/a-city-country-divide-more-than-70-percent-of-los-angeles-voters-picked-kamala-harris-for-president/ There were 12,700 rejected ballots in all of LA county: https://perma.cc/E5Y9-NURQ Orange County woman registered her dog: https://www.foxla.com/news/costa-mesa-woman-dog-voter-fraud-sentencing Heritage Foundation Voter Fraud Database: https://electionfraud.heritage.org/search

    California Election Counting Explained by an Actual Poll Worker

    California election counting has confused — and frankly ticked off — a lot of people, and I get it. I'm W. Curtis Preston, I've worked every California election since the 2016 presidential primary, and I've managed the polls at multiple elections here in San Diego County. This episode, I'm going solo to explain exactly what's going on, why it takes so long, what the "red mirage" actually is, and why none of it is fraud. Sorry to disappoint some of you. If you've ever had a family member call you asking "what the hell is going on over there?" — this one's for you. I walk through the specific changes California made to election law, how our system compares to Florida's, why human nature is a big part of the problem, and what the chain of custody for every single ballot actually looks like from the inside. This isn't punditry. This is someone who has stood at those poll books, sealed those ballot cartons, and escorted those ballots to the DART team. Chapters: 0:00 – Introduction: What the hell is going on in California? 1:23 – Who I am and why I can speak to this 2:12 – How California election law changed six years ago 4:43 – The mail ballot window: postmark by 8 PM, received within 7 days 5:09 – Vote centers vs. the old precinct model 7:39 – California vs. Florida: why the laws produce such different results 9:09 – Why California voters wait until the last minute 14:12 – The red mirage explained: it's not fraud, it's math 15:31 – Signature verification: 80,000–100,000 per day in San Diego alone 16:35 – How computers count ballots — and the 1% manual audit that checks them 19:11 – Chain of custody: two people, sealed cartons, tracked numbers 20:17 – Debunking the "law enforcement can't observe" myth 21:24 – Dead people voting?

    Stop 90% of Ransomware Attacks with Basic Cyber Hygiene

    Basic cyber hygiene — patch management, password management, and MFA — is responsible for stopping roughly 90% of the ransomware attacks that could hit your organization. This episode is the overview: what those three things are, why they matter, and what happens when you skip them. WannaCry infected over 200,000 systems worldwide. A patch existed. People just hadn't applied it. Rackspace lost an entire business line — not because the attack was sophisticated, but because a workaround gave them false confidence and they delayed a critical patch. These aren't edge cases. They're the rule. Dr. Mike Saylor (Black Swan Cybersecurity) and Prasanna Malaiyandi join me to walk through the three pillars of basic cyber hygiene. We cover patch management first — and before you can even patch, you have to know what you have. Inventory is the starting point. Then we get into passwords: why reusing them is a numbers game the bad guys always win, and why a password manager isn't optional anymore. Finally, MFA — what it is, which forms are actually worth using, and why "remember this device" is quietly defeating the whole point. This is an overview episode. We're going deeper on each pillar in three follow-up episodes. But if you're not doing these three things today, stop reading this and go do them. There's no point talking about EDR, XDR, or any other three-letter security product if you haven't nailed the basics first. It's like researching a Roth IRA when you don't have a savings account.

    Claude Deletes a Company — But It's Not Really Claude's Fault

    Claude deletes a company — and the internet immediately blamed the AI. But this story is really about backup design, credential management, and least privilege. An AI coding agent running Claude via Cursor deleted PocketOS's entire production database and all its backups in nine seconds. One bad design decision at a time, a startup built itself a disaster waiting to happen. Claude just happened to be the thing that set it off. Here's what you need to understand: the AI violated the principles it was given, and that's on Claude. But Claude never should have had access to do what it did. Credentials were sitting in a plain text YAML file. The production database and its backups lived on the same volume. No least privilege. No expiration on elevated permissions. And almost certainly, no backup recovery test — ever. In this episode, Curtis and Prasanna break down what actually went wrong with PocketOS, what Railway did to help recover the data, and what you need to do to make sure this never happens to you. Topics covered include backup isolation, the 3-2-1 rule, secrets management tools like AWS Secrets Manager and HashiCorp Vault, least privilege access, permission expiration, and credential scanning tools like TruffleHog. Chapters: 0:00 — Intro: Meet the villain 1:50 — Welcome and introducing "the French friend" 3:48 — What Claude actually did to PocketOS 7:20 — This is a backup story, not an AI story 9:27 — The recovery: Railway, a weekend of chaos, and a lucky Twitter post 12:31 — Your data is your responsibility — not your vendor's 17:48 — Rule #1: Never store backups inside production 20:37 — The real problem: credential management 23:38 — Secrets management tools explained 25:21 — Least privilege and why permissions need expiration dates 34:59 — Finding exposed credentials with TruffleHog 37:24 — Summary and takeaways
