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.

Synology DS418play NAS: data recovery from SHR-2 and SHR-1 RAID arrays

Read about how to recover data from an SHR-2 or SHR array (Synology Hybrid RAID) on a Synology DS418play NAS in a Windows 11 environment. We will review different data loss scenarios: accidental deletion of files or folders, volume formatting, and corruption of the storage structure. You will learn how to act in case of NAS failure or failure of one or more drives, and how to access information if the RAID array becomes unavailable and network shares no longer appear. A separate scenario demonstrates recovering data from a virtual LUN created in DSM.
