RTO and RPO without the fluff: two numbers signed but never calculated

Almost every continuity plan carries an RPO and an RTO written with great confidence and calculated with none. What those two numbers actually promise, why your real RPO is the one of your last verified backup, the four clocks inside an RTO, and the arithmetic that dismantles a "four hours" sitting on a 1 Gbps link.

Your backup server sits inside the domain it has to restore

In June, Veeam fixed a 9.4-out-of-10 flaw that let "an authenticated domain user" run code on the backup server. According to third-party technical analysis, on a workgroup server that flaw never came into existence. The difference is not in the code: it is in who your backup server asks whether you can be trusted. What it actually checks, why this is the sixth flaw with the same description in little over a year, the circular dependency nobody draws in the recovery plan, what taking the server out of the domain really costs, and the cases where we would not do it.

Restoring is not recovering: two in three recover from backup and nearly half still pay

Sophos's annual ransomware report (2,158 IT leaders across 17 countries, Spain included) brings the biggest backup rebound in the series: 66% of victims whose data was encrypted recovered from backup, twelve points above the 54% of 2025. At the same time 48% paid, and the average cost of recovering rose 11% to $1.7 million with the ransom excluded. Why the two numbers do not contradict each other, the note on method about the two medians almost nobody is reading correctly, what is inside that bill, and the five things worth timing before the bad day.

Three milliseconds and 44 degrees: the cloud outage that had nothing to do with software

On 15 July 2026 a three-millisecond voltage dip on the utility feed took three services in a Google Cloud zone in the Netherlands out of service for almost fifteen hours. No CVE, no botched deployment, no BGP route: an electrical transient, a backup system that failed to pick up the load, a chiller controller that dropped offline, and a data hall at 44°C. What exactly failed according to the official incident report, why redundancy on paper is not always redundancy, what it means that a zone is not a building, and the seven questions worth asking any datacenter — including your own — before it happens.

Romania's land registry
Wiped; saved by the out-of-reach copy

Romania's land registry was wiped, backups included. It was saved by the copy the attacker couldn't touch

On July 14 an attacker got into Romania's ANCPI with valid credentials, failed to extort the agency, and wiped the land registry database plus every backup within reach. A week with no property sales or mortgages nationwide. The difference between incident and catastrophe was one copy beyond his reach.
