BACKUPGUIDES

Share

If this year’s cyberattacks have taught us anything, it’s the importance of server backups and data redundancy.

While part of the problem is vulnerabilities and zero-day threats catching enterprise networks off guard, the sheer amount of data currently collected, stored, and processed is becoming too much to manage. 

Server backups for critical network resources address both of these problems by:

  1. Ensuring attackers don’t lock network users out of needed resources.
  2. Pushing organizations to identify and optimize data retention and security practices.

This article analyzes how server backups work, the difference between local and cloud backups, why backups are vital, and what backup solutions exist.

Table Of Contents

What Is a Server Backup?

Backup servers are the high-powered computers responsible for storing and protecting critical network data for the worst-case scenario. Whether it’s a hurricane, extended power outage, or advanced cyberattack, organizations need a method for restoring lost data. 

Local or cloud-based servers can back up files, folders, databases, hard drives, and more to ensure data persists outside of its day-to-day use as network resources.

With the rise of cloud solutions, backup services have become a significant vertical. Beyond the consumer cloud storage market, several vendors fight to secure the cloud server backup space for businesses.

How Do Backups Work in Cloud Computing?

With the development of cloud computing, cloud services help secure data in three ways. Rather than competing methodologies, the following often work in conjunction to serve the organization.

Cloud Storage

Simple storage of data

Cloud Backup

Automatic backup of data 

Cloud Sync

Active syncing between files

Local Backup vs. Cloud Backup

Any servers or other organization devices (e.g., tapes, disks, flash drives) holding redundant data on the physical premises are known as local backups. Not dependent on a third-party organization or the internet, local backups are accessible and reload system backups faster than remote cloud backup alternatives. 

Like many other cloud solutions, cloud backups are services offered by cloud providers and their army of remote servers and global data centers. Cloud backups are available on public cloud platforms (e.g., AWS, Azure, GCP), or organizations can establish and support backups via private cloud infrastructure. 

The benefits of cloud backups include reduced overhead, protection from natural disasters, access to data from anywhere, more robust security, and scalability. However, cloud backups take longer to reload or sync systems, cloud providers do not make switching easy, and networks are at risk of data loss when service contracts come to an end.

Hybrid Backups and the 3-2-1 Backup Rule

While local and cloud backups both have their benefits, it’s not good practice to rely on one or to limit your backups to a single copy. Industry professionals have come to agree on the 3-2-1 principle of backups:

For all pertinent data, you should have three copies of that data. One of these is your existing network doling out resources, while administrators should place the remaining two in different types of storage. One of those two storage mediums should be an off-site copy, such as a cloud backup.

Types of Data Backups

Full Backup

  • Copies everything
  • Heavy data load
  • Slowest to back up
  • High restore speed
  • Restores full backup

Differential Backup

  • Copies new changes
  • Medium data load
  • Faster to back up
  • High restore speed
  • Restores last full backup and last differential backup

Incremental Backup

  • Copies new changes
  • Small data load
  • Fastest to backup
  • Slowest restore speed
  • Restores last full backup and all incremental changes

The Importance of Offline Backups

In May 2021, hackers targeted the networks of energy company Colonial Pipeline and meat-processing company JBS, encrypting their data. Without access to network resources and afraid of further compromise, Colonial and JBS decided to shut down network segments or halt production. Many other companies have done the same in this situation.

One solution to deterring encrypt and extort schemes is offline backups, which remain untouched by the threat actors. In the examples mentioned above, ransomware gangs encrypted network data, preventing personnel and stakeholders from normal operations. Organizations must consider paying the ransom while continued downtime or even bankruptcy threatens the firm’s survival.

With an intact offline server backup, restoring the network could be done in the flip of a switch (and a chunk of buffering time depending on the organization’s size). While once limited to local servers, cloud backup services continue to offer SMBs access to a scalable, remote server solution.

Managing an Ocean of Data

Data can be both an asset and a disadvantage for organizations. It’s an asset because data can inform business decisions, but it’s a liability because of the risks associated with data loss. In both instances, the message is clear: take organization data seriously. 

Establishing a Recovery Plan

Organizations of all sizes today rely on storing data. Employee and customer information, proprietary documents, application code, e-mail servers, and more are examples of data best kept private. However, implementing a backup and recovery plan for enterprise networks is easier said than done. Our recommendations for getting started include:

  • Organize a detailed inventory of network components (software, hardware, and cloud-based)
  • Evaluate and record the volume of data for different network segments 
  • Identify pertinent data for retention and data that can be securely disposed
  • Ensure all systems, devices, and personnel adhere to regulatory compliance

Securing Data is Essential for Business Continuity

The thought that keeps cybersecurity professionals up at night is the threat of a data leak. Whether it damages the organization’s brand or puts the company in legal or financial jeopardy, consumers, public authorities, and organizations take data seriously. In addition to their clients’ sensitive information, businesses have proprietary data that allows them a competitive advantage in the marketplace.

While larger, more popular companies have received the brunt of cyber attacks over the years, no organization has ever been 100% digitally secure. Across industries, remote offline backups are an essential part of the toolkit to survive the next disaster.

Server Backup Market

Industry analysts forecasted the global server backup market was valued at around $5 billion in 2020, with the potential to double by 2026. This trend points to both the need to manage increasing amounts of data and the urgency to protect what’s most sensitive.

Cloud service providers continue to be a popular option by offering storage, sync, and backup capabilities to organizations. While Dropbox, Google Drive, and iCloud might be household names for consumers, businesses need to go much further in protecting sensitive data. Thus, the ability of cloud platforms to continually sync changes and automatically backup is crucial for organizations.

Backups: Preparing for the Worst-Case Scenario

The global economy is increasingly dependent on data. Because it’s at the heart of everything we do in a digital world, data intrinsically has a high dollar value. While natural disasters are less frequent, the digital threats presented by bad actors, malware, and human error make backup services essential. Prepare for the worst-case scenario by taking the time now to evaluate your organization’s sensitive data, server backups, and disaster recovery logistics.

What Is VMware Server Virtualization?

Many businesses deploy multiple servers for their IT needs, but in many cases these servers aren’t used at their full capacity, which leads to bloated operating costs and inefficiencies. One answer to this problem is server virtualization.

Server virtualization refers to the creation of software-based versions of the physical server. The process of virtualizing a server involves dividing one physical server into several isolated and unique virtual servers. The resulting multiple server instances operate in parallel, separated in terms of function but relying on the same underlying hardware.

Server virtualization provides businesses and IT professionals with an effective way to boost agility and productivity within an organization, while in many cases reducing IT hardware expenses by reducing the need for additional physical servers. Companies may also leverage server virtualization to mask resources on a server from users of the server. These masked resources might include the identity and number of processors, VM operating systems, and certain physical servers.

How Does VMware and Virtualization Work?

Now that you understand server virtualization, you may be wondering what the relationship is between VMware and virtualization. VMware provides virtualization software and is a popular choice among companies looking to leverage the benefits of server virtualization.

VMware server virtualization software offers a straightforward way to simulate hardware and establish a virtual computing system. Using a VMware server virtualization tool makes it easier for businesses to establish and manage a virtualized environment, as described below.

Virtual environments are made up of virtual machines (VMs). In IT infrastructures, a virtual computer system is referred to as a virtual machine—an isolated software container with an application and operating system inside of it. Every self-contained virtual machine will work independently. Having multiple virtual machines on one device allows several applications and operating systems to run on a single physical server. Virtual machines are separated from the host by a software layer called the hypervisor, which allocates resources to the VMs.

Using VMware virtualization technology allows businesses to more easily create and handle this kind of virtual environment. As a result, VMware server virtualization can allow businesses to maximize server resources and minimize the amount of hardware necessary for key operations. This consolidates the server, typically improving productivity and minimizing costs.

There are three types of server virtualization, which are outlined below.

1.   Full Virtualization

Full virtualization utilizes a hypervisor, a type of software that communicates directly with the physical server’s CPU and disk space. The hypervisor tracks the physical server resources and ensures every virtual server is kept independent and unaware of other VMs. Hypervisors also relay resources to the appropriate virtual server from a physical server, as applications are being run. The key limitation of full virtualization is hypervisors have their own processing requirements, which can cause a lag in application and server performance.

2.   Para-Virtualization

Para-virtualization entails the complete network operating as a single unit, which is different from how full virtualization functions. In para-virtualization, all virtual server operating systems are aware of each other, which means the hypervisor doesn’t need to consume as much power while processing and managing operating systems.

3.   OS-Level Virtualization

OS-level virtualization, which stands for operating system-level virtualization, doesn’t use a hypervisor at all. Rather, OS-level virtualization uses its virtualization capability (a part of the operating system on the physical server) to perform the hypervisor tasks and responsibilities. For this to work, however, all virtual servers have to run the same OS.

Benefits of VMware Virtualization Technology

This guide has already touched on a few of the benefits of VMware virtualization technology, but there are many more worth mentioning:

  • Quicker workload deployment
  • Improved performance
  • Increased server ability and reduced or eliminated downtime
  • Increased responsiveness and IT productivity
  • Increasingly automated operations, simplifying IT management processes and driving costs down
  • Ability to provision resources and applications faster
  • Simpler disaster recovery and business continuity
  • Simplified management of the data center
  • Establishes a software-defined data center
  • Lower operating costs
  • Mitigated server complexity

Best VMware Virtualization Management Software

As this guide has demonstrated, the benefits of virtualization VMware technology are significant. But unfortunately, implementing VMware server virtualization isn’t entirely straightforward. To make the most of server virtualization and ensure its ongoing success, it’s important for companies to use the right VMware virtualization software for monitoring and managing their deployments.

VMware Server (formerly VMware GSX Server) is a discontinued free-of-charge virtualization-software server suite developed and supplied by VMware, Inc.

VMware Server has fewer features than VMware ESX, software available for purchase, but can create, edit, and play virtual machines. It uses a client–server model, allowing remote access to virtual machines, at the cost of some graphical performance (and 3D support). It can run virtual machines created by other VMware products and by Microsoft Virtual PC.

VMware Server can preserve and revert to a single snapshot copy of each separate virtual machine within the VMware Server environment. The software does not have a specific interface for cloning virtual machines, unlike VMware Workstation.

VMware Server has largely been replaced by the “Shared Virtual Machines” feature, introduced in VMware Workstation 8.0 and onwards.[

Server Virtualization Definition

Server virtualization is the process of dividing a physical server into multiple unique and isolated virtual servers by means of a software application. Each virtual server can run its own operating systems independently.

Key Benefits of Server Virtualization:

  • Higher server ability
  • Cheaper operating costs
  • Eliminate server complexity
  • Increased application performance
  • Deploy workload quicker

Three Kinds of Server Virtualization:

  1. Full Virtualization: Full virtualization uses a hypervisor, a type of software that directly communicates with a physical server’s disk space and CPU. The hypervisor monitors the physical server’s resources and keeps each virtual server independent and unaware of the other virtual servers. It also relays resources from the physical server to the correct virtual server as it runs applications. The biggest limitation of using full virtualization is that a hypervisor has its own processing needs. This can slow down applications and impact server performance.
  2. Para-Virtualization: Unlike full virtualization, para-virtualization involves the entire network working together as a cohesive unit. Since each operating system on the virtual servers is aware of one another in para-virtualization, the hypervisor does not need to use as much processing power to manage the operating systems.
  3. OS-Level Virtualization: Unlike full and para-virtualization, OS-level visualization does not use a hypervisor. Instead, the virtualization capability, which is part of the physical server operating system, performs all the tasks of a hypervisor. However, all the virtual servers must run that same operating system in this server virtualization method.

Why Server Virtualization?

Server virtualization is a cost-effective way to provide web hosting services and effectively utilize existing resources in IT infrastructure. Without server virtualization, servers only use a small part of their processing power. This results in servers sitting idle because the workload is distributed to only a portion of the network’s servers. Data centers become overcrowded with underutilized servers, causing a waste of resources and power.

By having each physical server divided into multiple virtual servers, server virtualization allows each virtual server to act as a unique physical device. Each virtual server can run its own applications and operating system. This process increases the utilization of resources by making each virtual server act as a physical server and increases the capacity of each physical machine.
