Recovery of RAID5 and RAID0 Data from Windows Disk Management and Server Manager (WSS)

In this article we will examine how to perform data recovery from software RAID 5 and RAID 0 created using the Windows Storage Spaces and Windows Disk Management tools in Windows Server 2012. You will learn how to quickly restore access to information if the server fails, one of the drives malfunctions, or the operating system stops recognizing the RAID array. We will review common failure scenarios and demonstrate effective data recovery methods in environments where arrays are used for critical tasks: database storage, server services, or virtualization platforms.

How to recover data from ZFS: ZVOLs, datasets, snapshots, and virtual disks

Read about data recovery from the ZFS filesystem in TrueNAS 25.04.2.6. We will review how to analyze the pool structure and recover data from ZVOL, Dataset, Snapshot, as well as from virtual disks and virtual machines. We will cover common data loss scenarios, including array failures, failed system updates, hardware faults, and accidental deletion. All actions will be performed using Hetman RAID Recovery on Windows, while similar capabilities are also available on Linux and macOS.

How to recover data from Btrfs RAID 0, RAID 5, and RAID 6 arrays created on Rockstor

Read about data recovery from Btrfs RAID 0, 5 and 6 arrays created in the Rockstor 5.1 operating system based on OpenSUSE Leap. We will analyze scenarios of logical errors, including accidental file deletion via network protocols SMB/CIFS, NFS, SFTP, AFP, or cases where data has been severely corrupted. Special attention will be paid to hardware issues such as drive failures, server hardware or entire NAS failures, as well as Rockstor software faults after updates or accidental system-disk wipes.

ZFS Data Recovery: A Guide to RAIDZ1, RAIDZ2, RAIDZ3 and Stripe

In this article we review procedures for data recovery from RAIDZ1, RAIDZ2, RAIDZ3 and ZFS Stripe arrays created in the TrueNAS SCALE operating system. We demonstrate the sequence of actions in case of a hardware failure of the server and the methodology for restoring access to the data pool when one or more drives fail or data is accidentally deleted from the array.

How to recover video files from the Hikvision DS-7608NI recorder on macOS (HikvisionFS)

In this article we will examine how to recover video files from the network video recorder Hikvision DS-7608NI in a macOS environment. We will consider typical data loss scenarios: accidental deletion of individual files or entire folders, hard drive formatting, and corruption of the HikvisionFS file system. We will also separately address situations related to hardware failures — drive failure or malfunction of the recorder itself.
