How to Rebuild Data Disks in Unraid 7.3.1: Single and Dual Parity

In this article, we will examine critical data loss scenarios on servers running Unraid OS, specifically reliable data recovery from Single Parity and Dual Parity array configurations. We will look at how to correctly connect the server’s physical drives directly to a computer and prepare them for safe scanning. We will apply specialized approaches to reconstructing damaged arrays and recovering files depending on the number of functioning disks remaining.

Restoring files encrypted by EFS on an NTFS drive

In this article, we will examine a situation where files were encrypted using Windows EFS and then disappeared: they were accidentally deleted, formatted, or the partition was deleted, the NTFS file system became damaged, or access to the files was lost after reinstalling Windows. We will demonstrate how to work with the EFS certificate and private key on Windows, and how to work with encrypted files on macOS.

How to Recover Data from an Encrypted BitLocker Drive

Read about data recovery from drives protected by BitLocker technology. Reliable encryption effectively hides information from unauthorized parties, but it does not protect against hardware failures or human error. Accidental deletion of documents bypassing the Recycle Bin, incorrect partition formatting, or file system corruption are typical situations in which access to a drive suddenly disappears.

Recovery of Proxmox VE Virtual Machine Data from RAW, VMDK, and QCOW2 Disks

This article examines the process of data recovery from virtual machine disks in RAW, VMDK, and QCOW2 formats, as well as from Directory storage based on the Ext4 file system, created in Proxmox Virtual Environment 9.1.1. We will analyze the most common data loss scenarios: accidental deletion of files inside a virtual machine or of the virtual machine itself, data corruption caused by drive failure, server, PC, or NAS malfunctions, as well as software failures in Proxmox VE caused by updates, critical errors, or removal of the operating system.
