Wachy is a new Linux performance debugging tool that Rubrik recently released as open source. It enables interesting new ways of understanding performance by tracing arbitrary compiled binaries and functions with no code changes. This blog post briefly outlines various performance debugging tools that we commonly use, and the advantages and disadvantages of each. Then, we discuss why and how we built wachy.
Protecting your data in the cloud is fundamental to your security posture in terms of business continuity and disaster recovery. While Rubrik customers utilize the cloud every day to safely store off-site copies of their data, this blog is going to explain how we’ve made that practice even safer! We know that security threats to backup systems are on the rise, with hacking, malware, and even human error becoming more prevalent in the age of remote work.
It was 11 PM on a Friday in November of 2019. WED2B IT systems administrator Jamie Jeeves started receiving a barrage of email alerts warning that antivirus (AV) clients were crashing in the company’s central office. All prospects for a relaxing weekend vanished when Jeeves logged into the remote system to investigate the AV shutdowns. While checking the network’s file share, Jeeves noticed they were in trouble. Mass encryption of data was underway.
Part 2 in this series dealt with filesystem tree generation. In this part, we will look into the data of the files themselves and how they relate to tree generation.
Rubrik customers have an advantage when it comes to mitigating the log4j crisis. Utilizing our API-first architecture, Rubrik customers can make a single API call to find instances of log4j across their protected systems.
You run many of your business-critical applications on Nutanix AHV. Protecting your data from cyberattacks and being able to quickly restore your applications, so your business can continue as usual.

SAP HANA is often a database of choice for large enterprises looking to drive more significant insights and quick decision-making through real-time or advanced analytics. As a result, SAP HANA has become key to driving day-to-day operations for many organizations and must be protected to guarantee maximum availability. However, managing this protection is no easy feat.
Since January 2020, Microsoft Azure SQL DB has grown nearly 3x in popularity. This rapid growth comes as no surprise as Platform-as-a-service (PaaS) offerings have many benefits in the migration strategy from traditional SQL Server database workloads. The Microsoft PaaS offering, Azure SQL Database, takes care of mundane tasks once performed by Infrastructure Engineers such as patching operating systems and applying SQL Server updates or critical security patches.
Following up on our Simulating Filesystem Tree with Billions of Files series, let's imagine that we want to create a filesystem with 1 billion inodes in memory. At this scale, every single byte used to represent the inode will use 1GB of memory. Just with the inode numbers, each with 8 bytes, will use at least 8GB of memory. If we consider, conservatively, that each inode will use approximately 50 bytes of space, it will not be feasible to store this information in memory.
