In this article, we’ll tell you how to move a virtual machine from Hyper-V hypervisor to ProxmoxVE.

Nowadays, virtualization has become an integral part of IT infrastructure, and many companies use all kinds of hypervisors to launch their apps and services. Sometimes, users may need to move a virtual machine from one hypervisor to another. In this case, if you have a virtual machine working on Hyper-V and you would like to transfer it to Proxmox, you may need additional information about how to do it properly. Below, we will explore the steps you need to take to move a virtual machine successfully from Hyper-V to Proxmox.

Why you need to move a virtual machine?
There can be a few reasons to make you want to transfer a virtual machine from Hyper-V to Proxmox:

Transition to a different virtualization platform. If you have a virtual machine which you would like to run on a different virtualization platform, you may have to transfer the machine to that platform.
Better performance. If you notice that your virtual machine works too slowly or not too effectively on Hyper-V, moving it to Proxmox may improve the situation.
Software update. If you are planning to update your Proxmox or Hyper-V, you may need to transfer the virtual machine to a new platform.
Server failure. If one of the servers where the virtual machine is running suddenly breaks down, moving it to another server might be required to make sure that your work continues without any downtime.

In any of the cases I have listed, moving a virtual machine elsewhere could be the step you are required to take to preserve the system operability.

In this article, we’ll discuss recovering data from RAID 6 on Synology NAS DS2422+. We will explore how to configure backup schedule for important data, how to recover accidentally removed files from the recycle bin, and how to retrieve files if the RAID is degraded, completely destroyed, or if the NAS device is out of order. We will also have a closer look at fine details of configuration and recovery with the latest firmware version, DSM 7.1.

Synology is a well-known manufacturer of NAS storage systems. Typically, such devices as Synology DiskStation and RackStation NAS are easy to use and can be found in various RAID configurations, including RAID 0, RAID 1, 5, 6 and RAID 10. They also support their own storage configurations, SHR and SHR-2.

In the work of any network-attached storage, there may be certain issues that could result in loss of data. Quite often, users may accidentally remove important files, or there can be various problems that block access to data or cause data loss. Possible scenarios also include hardware breakdowns, wrong configuration, firmware issues and so on. If you lose access to files, the first rule is to stay calm and not to panic. Any wrong action at this stage often leads to losing all the information.

As is the case with any NAS, recovering data is never easy. To restore accidentally removed information or retrieve files from an inoperable NAS, you need a specialized software tool.

In this article, we’ll find out how to recover data from RAID 1 and RAID 0 based on Qnap TS-219P+ network-attached storage, how to recover accidentally removed files from the recycle bin, what to do if this option is inactive, if there is no access to the disk array because of a NAS failure, or if the RAID is degraded.

This QNAP NAS model is designed to use two hard disks. To improve resilience and data safety, such devices enable you to create RAID systems of various types. However, even the most reliable storage systems may encounter emergencies like accidental deletion of files, formatting or damaging the hard disk, system errors, controller failures and other hardware issues, which may result in loss of important data.

This specific model supports two RAID types, RAID1 and RAID0, as well as JBOD, which is sometimes referred to as linear RAID, but technically it isn’t a RAID at all. In the end, redundancy in this NAS is only achieved by using a mirrored RAID. But if one of the disks fails in either RAID0 or JBOD, a part of the information is bound to be lost. In this article, we will explore a situation when the NAS is broken; all the files are still on its disks but it’s impossible to retrieve them unless you use a specialized software tool.

The matter is that a NAS storage device uses its own operating system which builds the RAID in a certain way and then writes data to its disks. Even when the hard disks are connected to another storage device or computer, their condition cannot be restored.

For example, when the disks are connected to a Windows computer, you will see some partitions with an unrecognized file system; another possible case is that the operating system will suggest initializing them in the Disk Management app – which is going to erase all the data still remaining on the disks. So in the end, you are going to lose access to the files or even lose the files forever.

In a Linux operating system, the disk partitions will be displayed as Linux RAID, and the option to mount is unavailable.

You should remember that if you choose to initialize the hard disks in Windows or modify the volume in Linux, this action can erase all the information, and it will make recovery very difficult. Never take any steps involving the hard disks unless you really know what you’re doing, since there is a risk of losing your data permanently.

To retrieve the information from the hard disks, you will need a special tool to rebuild the RAID system and restore access to the files which are stored inside the disk array.

In this article, we’ll explore how to recover data from a crashed RAID based on a faulty Fujitsu D2516-C11 GS1 controller.

A controller is the main component of a RAID array because it provides the connection between the storage elements (hard disks or SSDs) and coordinates their work to create a logical pool of data. When the controller breaks down, the RAID array becomes inaccessible, and data recovery becomes an urgent need. In this tutorial, we’ll explore one of the most complicated situations related to RAID arrays – data recovery after a controller breakdown.

The RAID technology is a method to combine several storage devices (that is, hard disks) into a single logical unit in order to improve performance, reliability or both of these characteristics at the same time, depending on the disk array level. When the controller is out of order, the RAID may become inactive, and the access to its data will be lost. Data recovery from a crashed RAID requires specialized procedures and tools capable of restoring the files back to their normal condition.
