3-2-1 and immutable backups: how to check that your backups work
What the 3-2-1 rule is, what immutable backups add against ransomware and how to run a test restore to find out whether your backups actually work.

SRE, DevOps and systems for companies across Spain
Kubernetes, deployments and security for software companies. Servers, email and support for professional firms and SMEs.
Sound familiar?
The server, the app or the email stops working and nobody knows until a customer or a colleague calls.
They run every night, or so it seems. The day you need them, you will find out whether they work.
Servers, computers and apps on unsupported versions with pending patches, because there is no time or people are afraid to touch them.
Shared passwords, accounts belonging to people who have left and access that nobody reviews.
The access and the decisions are in their head. If they are away, nobody dares to touch anything.
In a free 20-minute call we look at where you are and where to start. No commitment.

Yes. If we are going to have access to systems with personal data, before we start we sign the data processing agreement under Article 28 of the GDPR, with the security measures and what happens to the data when we finish.
