The Beauty of Immutability

Imagine one or more of your systems is unavailable because of some malicious attack, whether a nasty virus, ransomware, or sabotage from a disgruntled employee. No worries, these things happen —  you’ll recover from backup. Except you discover that your backups have been compromised in the same manner (this has happened). This is usually where the term air gap gets dropped. Someone will say, “you need a truly offline backup — tape! There’s no way ransomware can get into a tape backup!” While that’s true, how long does it take to recover from tape stored in a land somewhere far, far away? If a backup takes so long to restore that there’s major financial or business impact, does it actually exist? Realistically, there are ways to protect your data stored by backup systems even without this gap. I recently wrote a blog post about immutable infrastructures, but compute infrastructures are not the only way that immutability matters in the data center. Immutable, by definition, means the state is set or inflexible once constructed. In other words, it cannot be changed. The goal is to build a more reliable automated compute infrastructure in order to enable stable continuous delivery. Data has become…

Worried About Viruses? Ransom? Data Loss? The Cure is Here!

This is not hype! This is reality. Companies across industries get hit with viruses all the time. In the always-on economy, companies rely on 24/7 data availability, so any downtime can severely impact the business. The good news is that with a strong data management solution, you can quickly recover from a disaster without any data loss. Before we dive into how Rubrik delivers that solution, let’s go over what happens during a virus attack. The Lifecycle of a Virus Attack Before Rubrik As the above diagram shows, a typical attack has several phases: you get hit with the virus, your systems are under attack, and your business loses access to the encrypted data. Once it’s detected, your IT team documents and implements steps to prevent the virus from spreading. But since most organizations rely on data to perform daily operations, the data loss you’ve already experienced has a severe impact on the organization. Unfortunately, for many organizations, a virus’ life doesn’t end with patching the vulnerability. Even with a sophisticated antivirus software, viruses can remain in your system undetected. This often leads to further data corruption and a vicious cycle of attack, recover, and patch. For this reason, many…

Rubrik & Oracle: Not Just a Dumb Target

Oracle databases are a critical part of many IT environments. With the Rubrik Alta release, we are excited to announce support for Oracle. Our goal is to provide core Rubrik benefits such as immutability and a single policy engine for retention + archival + replication, while tightly integrating with native Oracle capabilities. Our approach is to integrate with RMAN to offer agentless support and allow Oracle DBAs to continue using familiar tools. The integration provides support for ASM – a notable difference from array-based snapshot methods. Rubrik supports all database topologies (RAC, Exadata, etc.) and recovery types. While an easy and technically feasible approach would have been providing an NFS export and stopping there, Rubrik is intentionally not a “dumb target” for database backups. Our engineers rejected that approach as not staying true to the core Rubrik platform benefits. However, we are using NFS as a transport mechanism for ingesting RMAN backups into Oracle. From there, Oracle backups are preserved in an immutable format and managed via the same Rubrik policy that applies to all other datasets. Under the Hood The core new feature that supports Oracle backups is the concept of a Managed Volume – an NFS mount point exposed to…
