What is a Virtual Machine?

Virtual Machine (VM), also known as virtualization process, is a technology that allows you to integrate a virtual system into your computer in a totally isolated way.
Recover Virtual Machines

Virtual machine (VM), also known as the virtualization process, is a technology that allows you to integrate a virtual system into your computer in complete isolation. So that everything that runs in the virtual environment does not affect the rest of your computer.

A virtual machine (VM) is a powerful tool that can be used to create and run multiple operating systems, including applications developed for other platforms such as Windows or Mac.

In other words, a virtual machine is a computer that runs inside another computer. Within this environment you can run different types of software, such as applications and games.

The concept came about when there was a huge growth in data movement. The companies that were advancing their technologies needed to somehow compress their systems.

This is where cloud storage came in, which when connected to a network, all your data is stored without taking up internal disk memory.

However, a cloud has a huge load of data and files, and to manage this large demand, virtual machines were created.

With them it was possible to join several virtual systems into just one physical system, saving resources, space and even possible employees.

What does Virtual Machine mean?

There are several models of virtual machines, we will look at the main ones below:

Microsoft Hyper V

Hyper-V Recovery

Hyper-V is a Windows 10-based platform that helps businesses leverage the virtualization capabilities of Microsoft Windows. It enables enterprises to run multiple operating systems on one computer, allowing them to save time and money when it comes to IT support.

In addition, Hyper-V can help reduce data transfer costs and improve network performance for businesses.

The software product already helps thousands of administrators manage virtual machines (VMs) and applications on different systems.

Hyper-V Central provides a central location to manage VMs and applications, as well as tools to help with installation and configuration.

How to Install Hyper-V

Installing Hyper-V is very easy. The installer takes care of everything for you and it only takes a few clicks to get started.

But, as always, there are a few things to remember before starting the installation.

First of all, make sure you have the latest patches installed on your system. Otherwise you will need to update them as soon as possible.

Second, be prepared for a few surprises during the installation process. Don’t be surprised if Hyper-V starts slowly or even crashes sometimes. Just remember that these things usually happen in beta testing – and that’s okay.

Third and last, be aware of how Hyper-V affects the performance of your network. Make sure you can see all your devices and resources while running RIPTooling or similar tools.

Hyper-V Installation Step By Step

To install Hyper-V, first create a new folder on your computer where you will save the Hyper-V installer files.

Then run the Hyper-V installer from this folder. The installer will take a few minutes to start.After completion, you can open the Hyper-V shell in your new folder and start the hypervisor installation.

Use Hyper-V to interface with your devices

Hyper-V is perfect for connecting device types such as network adapters, printers, smartphones, tablets, and even digital cameras. You can easily connect these devices using hypervisors in the same Windows environment.

This means that instead of finding an appropriate physical connection or configuring each device separately, you can manage them all in one place – making life much easier when it comes to deploying or running applications or services on these systems.

To be successful with Hyper-V, it is important to keep your desktops and laptops separate from each other. That way you can continue to use your traditional Windows applications while your servers run in their own virtual environment.

In addition, you should avoid using Hyper-V on systems used to produce video content or games-these systems will need to use alternative virtualization platforms, such as VMware or Microsoft’s own Xbox 360 emulator.

How to Use a Virtual Machine?

There are many ways to use a virtual machine, but four of the most widely used are as follows:

  • Use it as a window to open programs: When running an application through a virtual machine, you can switch between your normal windows and the application’s virtual operating system window. This allows you to multitask and speeds up processes.
  • Use it as a copy of another computer: If you want to run an application on one computer and access its resources on another, you can use a virtual machine. This is useful if you need two computers to do something (like create a spreadsheet) or if one of your computers is unavailable for some reason (like while traveling).
  • Use it as a boot camp: As well as being used as an emulation of other computers, virtual machines can also be used as a boot camp for software development exercises or for learning programming skills. By running various software on different shells (or versions), you can learn how each program works without actually having any code installed on your own computer.
  • Use it as an emulator for obsolete or older hardware: As mentioned in the advantages, virtual machines usually include support for older hardware so that you can run applications on their older versions using modern operating systems and drivers. This function is very helpful when you need to run older applications that have been discontinued but are still available online somewhere.

The Advantages of Using a Virtual Machine

Virtual machines can speed up many processes. There are several reasons why you might want to use a virtual machine for such.

For example, a virtual machine can run faster than a physical one, allowing you to work on more demanding tasks more efficiently. This can save time and money in the long run.

VM can also be used in combination with cloud services so that companies can make the most of their technology investments, for example, with it you can test the functionality of online services and websites.

In addition, they can be used for various purposes, including learning new programming languages, playing video games, or debugging software without affecting the main system.

By operating within the virtual environment, it is also possible to run and use previous versions of applications and software without having to update them.

Economically, operating multiple machines within one reduces the costs of developing new technologies.

What Are Snapshots in Virtual Machines?

In the field of data recovery we are used to dealing with various situations of data loss linked to this type of technology, not by application error (which does not exclude this possibility) but by human error.

Misuse, or lack of experience, can make the task of managing snapshots a mission-critical one, and almost always the scenario of data loss is almost certain.

What is Snapshot?

A common error is understanding what the snapshot is, a good number of the cases we receive for data recovery carry this error in them. But what mistake? Thinking that the snapshot is a backup, but this is not true.

The snapshot is a kind of freezing of the main virtual machine and creation of a new machine attached to the main virtual machine without using it consequently.

The new data is saved in this kind of backup and does not consume the space and performance of the main machine.

Imagine the following scenario: You have an application running on the main virtual machine and you need availability without interruptions, but the volume of data was not well calculated initially.

In this case, the snapshot is a great tool to receive this new data from the main machine.

There are some best practice recommendations for the consolidation process of this new data:

  • It is recommended to use the snapshot for 72hs, after that it is necessary to consolidate the data on the main virtual machine.
  • Do not allow the snapshot to have a large size. The larger it is, the longer the data consolidation process takes. We have noticed that the consolidation process in high-availability environments becomes difficult to handle.
  • Don’t have more than 3 snapshots.

What Are the Extensions of the Main Snapshots?

  • Vmware: Delta
  • Microsoft: AVHD, AVHDX

Problems Causing Data Loss in Virtual Machine

Deleting Data

It is very common for VM users to end up deleting their data believing that they have a backup or that the file is stored somewhere else. But unfortunately, many are mistaken and lose their data

Information Corruption

The action does not happen often, however, there is still the possibility of data corruption. When there is a power failure, for example, the software can fail and files are lost.

Formatting partitions

Partitions are the data that is stored outside the main operating system, i.e. when partitions are formatted, the information is deleted.

Information overlap

Data overwriting is a very common error that happens in data centers. The failure occurs when one file is placed on top of another, either a more up-to-date version of the same file, or even another file. This ends up deleting the original version of the data

Formatting followed by system reinstallation

When a machine is formatted, all storage will be deleted, if a backup has not been made, all information will be lost.

Malfunction, burnout or breakdown of the virtual machine manager's storage system

In cases of physical damage, even VMs can be affected because the hardware will be damaged, resulting in data loss

Simultaneous failure of hard disks in Storages

When more than one disk is corrupted at the same time, the information contained on them will be deleted.

Recovering data from Virtual Machines

We have developed unique technologies for recovering Virtual Machines. Our years of experience in data recovery have given us the expertise to work through the most complex data loss scenarios. Recovering databases was a challenge we were able to overcome.

Virtual Machines (VM) are operating system managers designed to take full advantage of the performance and resources offered by servers and storage.

Allied to RAID systems, this resource becomes a Swiss army knife. Through these managers it is possible to transform a single physical server into several virtual servers.

In other words, instead of buying a server for each type of application (file server, database, e-mail, and internet), you buy just one scalable server and install a virtual machine manager on it to run several servers of various platforms at the same time.

With the virtual machine manager you can share or allocate resources to each virtual server according to demand. If at some point the physical server needs more resources, just add memory, disks or processors.

How to Recover Virtual Machines After Ransomware Attack

Even with all the losses mentioned above, the main one and the one with the biggest losses, are ransomware attacks.

After virtual machines are attacked by ransomware, there are not many things a technician can do except turn to a company that specializes in recovering files encrypted by ransomware.

Perhaps, for the sake of conscience, it is worth resorting to archaic means and disconnecting the network cables that distribute Internet access after being attacked.

The reality is that after guests are attacked, the fear is that they will not have public folders that are shared directly with the host.

In fact, if during configuration there is a public folder, this has become the best of all worlds for hackers, as this way they will get a range of privileges that was not in their effective plan of attack before.

There is a logic, that needs to be clarified, the more data that is hijacked, the more valuable and vital the encrypted data is, the higher the cryptocurrency payment ticket, to get access to the decryption key.

This is somewhat logical, however it needs to be clarified, as cybercriminals will always be crafty and the more they know that the data is critical, the chance they have to increase the value to be traded.

Sharing valuable information, passwords, system access, in a reckless manner, are simple ways to be manipulated, found, and hacked.

A valuable tip is to use two or more factor authentication passwords for system access, passwords that expire every 10 seconds, encrypted environments, where trying to access the master password is extremely difficult.

The way hackers travel the Internet, at similar levels of security, the way they value privacy and access sites, are important signs that need to be replicated in our daily lives.

Neglecting the reality that the Internet is a hostile environment is the beginning of successful ransomware attacks. Avoid at all costs, bad habits around all online work.

Avoid contact or negotiation with criminals, because from the facts and evidence there is no question that the psychological shaking of victims makes them totally vulnerable and easy to manipulate.

Count on Digital Recovery to recover files encrypted by ransomware, we can recover ransomware of any extension even without the decryption key.
