Differences between NAS, SAN and DAS:
How does it affect recovery?
Each storage architecture has unique characteristics that determine the complexity of the data recovery process.
Network-attached storage for SMB and home use
Medium complexity. Filesystem Btrfs/ext4, proprietary firmware according to manufacturer.
Block-level enterprise storage network for servers
High complexity. LUNs, volume groups, and proprietary metadata make recovery especially demanding.
External local storage for server or workstation
Low-medium complexity. Similar to standard disks, although it can include multiple disks in JBOD.
Most common failures in NAS, SAN, and DAS
These are the scenarios we see most often in the lab. Knowing them helps not to make the situation worse before contacting us.
RAID degraded due to disk failure
The array loses a member and goes into demote mode. If more disks are lost before replacement, the volume may collapse completely and the data may be inaccessible.
Btrfs, ext4, or XFS filesystem corruption
A power failure during a write can corrupt the superblock and leave the volume inaccessible to the mount, even though the data is still physically intact on the disks.
NAS firmware failure
A failed DSM (Synology) or QTS (QNAP) update can leave the system in boot loop, inaccessible over the network, with no possibility to mount volumes.
DeadBolt and eCh0raix ransomware
Variants specifically designed for Synology and QNAP NAS. They encrypt user files while keeping the operating system active, which can make you believe that the device is working normally.
iSCSI configuration loss
The loss of metadata from an iSCSI LUN can render volumes inaccessible even though all physical data is completely intact on the disks.
RAID SAN controller failure
The controller fails and the disks in the array cannot be read by another controller without knowing the exact configuration: disk order, strip size, and parity.

Secure shipping includedWhat to do if your NAS, SAN, or DAS device has failed?
A NAS, SAN, or DAS device is a compact enclosure consisting of multiple hard drives that are connected via network cable or direct interface to the system. If you have problems with it, it doesn't work or you can't access the data, our recommendation is to disconnect it and contact a specialized data recovery service.
If you tamper with the device or try to recover data with a program without success, you could complicate and make the recovery process more expensive — even to the point of making it unrecoverable.
-
1
Turn off your device as soon as possible. It will prevent further damage that may condition the recovery process. Each power-on cycle with a degraded RAID or corrupt filesystem can worsen the state of the data.
-
2
Do not tamper with the device improperly. Forcing screws or opening it in an uncontrolled or dust-free environment can negatively affect the chances of recovery. The interior parts are extremely sensitive and delicate.
-
3
Avoid recovery software in physical cases. In the event of mechanical or controller failures, using a recovery program can permanently damage the device and reduce – or eliminate – the chances of recovering data.
-
4
Contact a laboratory specialized in data recovery. They are the professionals who have the tools, equipment and appropriate training to evaluate the case and carry out the extraction and recovery processes with guarantees.

ContactWhat determines the price
to recover a NAS, SAN or DAS?
The cost is highly variable: it depends on whether the failure is physical or logical, the number of disks in the array, and the type of RAID used. At Laby we never charge more for the volume of data, only for the real difficulty of the process.
Type and origin of the failure
A logical failure – deletion of a virtual machine, corrupted snapshot – is not the same as a physical failure in the cabin or in the disks themselves. The origin of the problem radically marks the process and the cost of recovery.
Number of disks and RAID
It is not the same to work with 4 discs as with 16. The more disks that are damaged, the greater the complexity. In addition, it is necessary to know the type of RAID: RAID 0, RAID 5, RAID 6 or others, since each one has a different reconstruction process.
Working hours
The complexity is determined by imaging the damaged devices in the laboratory and clean room, and by overcoming the RAID parameters: block size, offsets and parity. The more discs and the more damage, the more hours of work.
Complex file systems
EXT3/4, XFS, and VMFS systems are extremely robust against file corruption, but deleted data recovery processes are not always possible due to their own design.
On VMFS systems, once the RAID is mounted, the VMFS container may also need to be mounted to display the contents of the virtual machines, adding an additional layer of complexity.
RAID over SSD — TRIM factor
If the disk set is SSD, the TRIM command can be decisive: it marks the deleted blocks as immediately available, making the data unrecoverable if the system is still active.
In a logical problem such as a corrupted deletion or snapshot, it is imperative to stop the NAS, SAN, or DAS immediately to prevent information from being overwritten.

FAQs about NAS, SAN, and DAS Data Recovery
What level of urgency do you guarantee for companies with production stoppage?
Our commitment is business continuity. We activated an emergency protocol that includes:
SLA Response: Less than 2 hours from first contact.
Express Diagnosis: Results within 4 hours of receiving the device.
24/7 Operation: Rotating shifts in the laboratory until the data is dumped.
Dedicated Technician: A single senior contact person assigned exclusively to your issue.
Is it possible to recover data from a NAS encrypted by Ransomware?
Viability depends on the type of incident:
Volume Encryption (AES-256): If it’s a native QNAP/Synology encryption, we recover the structure, but we’ll need the key or file
.keyfor final access.External Attacks (DeadBolt, eCh0raix): We analyze whether the version of the malware has known vulnerabilities or leaked keys. In critical cases, we assist in the evaluation of the attacker’s key.
Do you support complex architectures such as iSCSI LUNs or Fibre Channel?
Yes. We are specialists in block storage.
We rebuild iSCSI LUNs and volumes in SAN (FCoE/FC) environments.
Even if the target mapping map or HBA has been lost, we perform controller metadata analysis to manually reassemble the blocks and extract the information.
Btrfs vs. ext4: Which Has Better Recovery Options?
Both systems have their particularities in the laboratory:
Btrfs: It is structurally more complex ( B-trees and Copy-on-Write), but its snapshot system is a salvation; It often allows us to “travel back in time” and extract versions of files that predate failure or deletion.
ext4: It is a more linear and predictable system. In the event of severe physical failures on RAID disks, it offers a slightly higher success rate due to its simplicity.

What devices do we recover at Laby?
Mechanical Hard Disks
HDD disks have as main components the metal plates where data is stored, and the heads that access the information. The most common hard disk.
SSD Hard Drives
SSDs have no moving parts — hence "solid state." Information is stored in blocks with no heads required. Much more efficient and faster than HDD.
External Hard Drives
External hard disks let you store important backups outside your computer. A single failure can cause you to lose all that valuable data.
iPhone, iPad, iMac or MacBook
Apple devices including iPhone, iPad, iMac, MacBook and Mac Mini. Reliable, elegant and powerful — and fully recoverable when something goes wrong.
Laptop Hard Disks
Your laptop holds important work and personal data. If a failure occurs, all that valuable information can be at risk — we can get it back.
NAS, SAN and DAS Disks
A compact enclosure of several hard disks connected via network cable to the system. Commonly known as a network hard disk — we recover all configurations.
RAID Systems
RAID disks are a redundant group of independent disks (HDD or SSD) forming a storage system to distribute or replicate data across multiple drives.
Pen Drives and USB Flash Drives
Pen drives consist of one or more memory blocks using the same Flash technology as SSD devices, making them fast but vulnerable to sudden failures.
Memory Cards
Memory cards store data from cameras, phones and tablets. They vary in capacity and speed — and when they fail, we recover what matters most.
Virus or Ransomware
We recover data encrypted by viruses or ransomware. Ransomware blocks your device until a ransom is paid — depending on the type, it encrypts the full OS or specific files.
Mobile Phones and Tablets
Recovery from smartphones and tablets is carried out by analyzing the electronics of damaged components or through the chip-off process for deeper failures.
Data Deletion
We offer certified secure data erasure and destruction, carried out either in our laboratory or remotely, with full documentation for compliance and legal purposes.
Forensic Analysis
Computer forensic analysis and expert evidence. We recover and certify critical information with legal value, with certified experts for reports and legal proceedings.
