Zerto

Zerto is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zerto rather than just read about it. In short: Zerto provides disaster recovery, ransomware resilience and workload mobility software for virtualized infrastructures and cloud environments. Zerto is a subsidiary of Hewlett Packard Enterprise company which is headquartered in Spring, Texas, USA.

Key takeaways

Zerto belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Zerto to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Zerto from memory before moving on to harder problems.

Reference excerpt

Zerto provides disaster recovery, ransomware resilience and workload mobility software for virtualized infrastructures and cloud environments. Zerto is a subsidiary of Hewlett Packard Enterprise company which is headquartered in Spring, Texas, USA.

History Ziv Kedem, Zerto's founder and CEO, previously co-founded Kashya. Zerto has received investments from venture capital firms such as 83North (formerly Greylock IL), Battery Ventures, Harmony Partners, RTP Ventures, IVP, and USVP. In 2016, the company was ranked #45 on the Deloitte Fast 500 North America list. Zerto was bought by Hewlett Packard Enterprise in 2021 for $374 million.

Products Zerto simplifies the protection, recovery, and mobility of on-premises and cloud applications. Zerto’s simple, software-only solution uses continuous data protection at scale to solve for ransomware resilience, disaster recovery and data mobility across private, public, and hybrid deployments. Zerto supports VMware, Hyper-V, AWS, Microsoft Azure, IBM Cloud, Google Cloud, Oracle Cloud, and more than 350 managed service providers. Zerto provides disaster recovery software for virtualized and cloud infrastructures. The company's original product, Zerto Virtual Replication, was released in August 2011. The technology leverages 'hypervisor-based replication', which moves data replication up the server stack from the storage layer into the hypervisor. Zerto Backup for SaaS powered by Keepit introduced in 2021 provides a simple cloud backup built on the world’s only secure cloud dedicated to SaaS data protection and includes support for Microsoft 365, Salesforce, Google Workspace, Zendesk, Microsoft Power BI, Microsoft Dynamics, and Microsoft Active directory.

Worked examples

Example 1 — a first encounter with Zerto

Start with the simplest possible case. Write down what Zerto claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zerto before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zerto ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zerto

In research: Zerto appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Zerto in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Zerto is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 establishments in Massachusetts, 2021 mergers and acquisitions, Disaster recovery, so understanding it makes those chapters shorter.
In everyday life: Look for Zerto outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Zerto in simple terms?

Why does Zerto matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Zerto?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
