Recovery Virtual Machines

Virtual Machine (VM), also known as virtualisation process, is a technology that allows you to integrate a virtual system into your computer in a totally isolated way. So that whatever is run in the virtual environment will not affect the rest of the 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 it is possible to 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 compact their systems.

From there, cloud storage emerged, which when connected to a network, all your data is stored without occupying the memory of the internal disk.

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

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

Virtual Machine Models

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

Microsoft Hyper V

Recovery Hyper-V

Hyper-V is a Windows 10-based platform that helps businesses leverage the virtualisation capabilities of Microsoft Windows. With it, businesses can 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 across 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 you start the installation.

Firstly, 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 OK.

Third and last, be aware of how Hyper-V affects your network performance. 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 begin installing the hypervisor.

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 virtualisation 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 streamlines 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 travelling).
  • Use it as a boot camp: In addition to 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 previous 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 you 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 several machines within one reduces the costs of developing new technologies.

What are Snapshots on Virtual Machines?

In the area 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.

Improper use or lack of experience can make the task of managing snapshots a mission critical and almost always the scenario of data loss is almost certain.

What is Snapshot?

A common error is the understanding of what snapshot is, a good portion of the cases we receive to recover data carry in themselves this error. But, what mistake? Thinking that the snapshot is a backup, however, this is not true.

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

The new data are recorded in this kind of backup not consuming 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 good 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 in 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.
  • Do not 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

Deletion of data

It is very common that VM users 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

Corruption of information

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.

Overlapping information

Data overwriting is a very common error that happens in data centres. The fault occurs when a file is placed on top of another, either a more updated version of the same, 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 storage system

In cases of physical damage, even VMs can be affected as the hardware will suffer damage, 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 to recover Virtual Machines. Our years of experience in data recovery have given us the expertise to work in 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 make the most 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.

That is, instead of buying a server for each type of application (file server, database, email and internet), you only buy 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 for each virtual server according to demand. If at any time 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 with the biggest losses, are ransomware attacks.

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

Perhaps, for the sake of conscience, it is valid to resort to archaic means and disconnect the network cables that distributes access to the Internet, after having been attacked.

The reality is that, after the guests are attacked, the fear that remains is not to 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, because this way they will achieve a scale of privileges, which before was not in their effective plan of attack.

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 cunning and the more they know the data is critical, the chance they have to increase the value being traded.

Sharing valuable information, passwords, system access, recklessly, 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.

In the same way that hackers travel through the internet at similar levels of security, the way they value privacy and access websites 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 a successful ransomware attack. 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 on the part of victims, make them totally vulnerable and easy to be manipulated.

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