Guide to RAID, server and NAS data recovery for business

- ISO 9001/27001 ISO certifications
RAID, server and NAS data recovery is the set of technical procedures used to restore business-critical information from damaged or inaccessible disks, arrays and storage systems. At TN Solutions we handle hardware failures, logical errors and ransomware attacks with ISO 27001-certified diagnostics and cleanroom facilities, safeguarding the integrity and confidentiality of every recovered file.
For more than 25 years we have worked as a B2B System Integrator in Melzo (Milan), supporting SMEs and structured organisations through their most critical moments: a RAID array that will not rebuild, a server that no longer boots, a business NAS that has dropped offline. Below we explain how recovery works, when it is genuinely possible and how to act in the first few hours.
What is RAID, server and NAS data recovery (definition)
Data recovery is the process of extracting and reconstructing files, databases and virtual machines from storage media that has suffered a malfunction. In a business context this rarely means a single disk: it means complex infrastructure such as RAID arrays that spread data across multiple drives, servers with dedicated controllers and NAS units running proprietary file systems.
Recovering data from these systems demands expertise in array geometry, disk order, stripe size and configuration metadata. An improvised attempt often makes the data permanently unrecoverable. That is why professional recovery always begins with a non-destructive diagnosis.
When you need data recovery: hardware, logical and ransomware failures
Business data loss falls into three broad families, each requiring a dedicated approach.
Hardware failures
Stuck heads, seized motors, burnt-out electronics, drives that make unusual noises or are no longer detected. When mechanical damage is involved, the disk must only be opened inside a cleanroom, so that dust and humidity cannot compromise the platters.
Logical errors
Accidental deletions, reformatting, file system corruption, RAID rebuilds interrupted or run with the wrong disk order. In these cases the hardware is intact, but the logical structure of the data is broken.
Ransomware and encryption
An attack that encrypts shared volumes can bring your entire operation to a standstill. Here recovery focuses on shadow copies, snapshots, backups the encryption did not reach and, where feasible, decryption. This is an area where sound IT infrastructure security management makes all the difference.
How the TN Solutions recovery process works: diagnosis, cleanroom and verification
Our method follows precise, fully traceable stages in line with ISO 9001 procedures.
- Intake and diagnosis. We assess the state of the media without writing to the original disks and give you a clear picture of the likelihood of success, timescales and costs.
- Sector-by-sector cloning. We always work on forensic copies of the drives, never on the originals, so we never make the situation worse.
- Cleanroom intervention. When the damage is mechanical, disks are opened in a contamination-controlled environment to replace the failed components.
- Logical reconstruction. We rebuild the RAID array, the file system and the folder structure from the copies.
- Verification and handover. We check that the recovered files open correctly and are intact, together with you, before delivering them on secure media.

RAID data recovery: levels 0, 1, 5, 6, 10 and complex configurations
Every RAID level presents its own challenges. RAID 0, with no redundancy, requires recovery from all disks at once. RAID 1 lets us work on the surviving disk when its mirror fails. RAID 5 tolerates the loss of a single disk, but becomes critical if a second drive degrades during a rebuild. RAID 6 offers double parity and greater resilience, while RAID 10 combines mirroring and striping.
In the most demanding cases we work on arrays with dozens of disks and nested configurations. The configuration you choose at the outset has a major impact on recoverability: learn more in our guide on how to choose the right RAID.
NAS and server data recovery: Synology, QNAP and business file systems
Business NAS units use specific file systems and volume managers, such as Btrfs and ext4 on Synology, or ZFS and proprietary volumes on QNAP. Recovering data from these systems means correctly interpreting the software structure as well as the physical condition of the disks.
As a Synology partner we work on degraded volumes, corrupted snapshots and SHR configurations, as well as servers running databases, virtual machines and network shares. A deep understanding of the different hard disks, SSDs and NAS devices lets us choose the safest approach for each technology.
Why choose TN Solutions: ISO 9001 and 27001, 25 years of B2B experience
Entrusting your business data to a recovery lab means entrusting your operational continuity. TN Solutions is a System Integrator with over 25 years of experience, certified to ISO 9001 for process quality and ISO 27001 for information security.
We are partners of HP, Dell, Microsoft, Lenovo, Synology and WatchGuard, with a Google rating of 4.7 across 37 reviews. Every recovery is tracked, documented and covered by confidentiality agreements: your data stays under our control and is never shared with third parties.
Preventing data loss: backup and disaster recovery
Data recovery is the emergency remedy, but real protection comes from prevention. A well-designed backup strategy, with multiple copies kept off-site as well, dramatically reduces the impact of a failure.
We design tailored backup and disaster recovery plans for business and help you prevent data loss with regular restore testing. After all, a backup that has never been tested is not a real backup.
Frequently asked questions
How much does RAID or business NAS data recovery cost?
The cost depends on the type of failure, the number of disks and the complexity of the array. That is why we always start with a diagnosis that, before any work begins, sets out the likelihood of success, the timescale and a transparent quote. Nothing proceeds without your approval.
Can data be recovered after a ransomware attack or an accidental deletion?
Often, yes. After an accidental deletion the odds are high if you stop using the system immediately. In a ransomware scenario we check snapshots, shadow copies and unencrypted backups, and assess any decryption tools available for the specific variant involved.
How long does data recovery from a server or a damaged RAID array take?
Diagnosis usually takes a few hours to a few days. Full recovery ranges from one to several days depending on the extent of the damage. For critical situations we activate emergency interventions with dedicated priority, minimising operational downtime.
What should I do (and avoid) immediately after a RAID or NAS failure?
Shut the system down and do not attempt rebuilds, reformatting or repeated restarts: every write risks overwriting recoverable data. Do not replace the disks or change their order. Note down what happened and contact us before taking any further action.
Is my data safe and confidential during the recovery process?
Yes. We operate under ISO 27001 certification, with confidentiality agreements and full traceability. We work on forensic copies, store the media in a protected environment and deliver the recovered data on secure media, without ever sharing it with third parties.
