NAS recovery for Synology, QNAP and WD My Cloud in Warsaw

A NAS gives convenient central access to documents, photos, backups and business data, but it can also create a false sense of safety. RAID redundancy is not the same as a backup, and a rushed repair in DSM, QTS or another NAS panel can write over the very metadata needed for reconstruction.

Safe NAS recovery usually starts by deciding whether the problem is in the drives, RAID configuration, file system, snapshots, ransomware damage or a change already made after the failure. The goal is not to make the box boot at any cost. The goal is to keep the data recoverable.

With which breakdowns NAS goes to the laboratory most often

• Synology or QNAP volume marked as degraded, crashed, offline or not mounted.
• Lost shares after a DSM/QTS update, power outage, migration or reset.
• lack of access to shares despite visible disks,
• ransomware, encrypted shares or logical data damage,
• incorrect migration, disk exchange or device reset,
• WD My Cloud or similar NAS visible on the network, but without access to files.

Which is not to do after the crash of the NAS

1. Do not start rebuild or resync unless you know exactly which disk failed and have a safe copy of the remaining disks.
2. Do not initialise a new volume, create a new storage pool or accept automatic repair prompts.
3. Do not update firmware during the incident just to see whether the volume returns.
4. Don't assume that if NAS turns on, the data is safe.
5. Do not keep services, virtual machines or backup jobs writing to a degraded array.

What it looks like to be a safe recovery of data from NAS

Laboratory work normally begins with risk assessment and imaging of the member drives. Reconstruction is then performed on copies, not by experimenting on the original NAS. Depending on the case, the work may involve RAID parameters, LVM or storage pools, EXT4, Btrfs, XFS, snapshots and encrypted or ransomware-affected data. The reconstruction is not carried out on the original disks without confirming the system parameters.

If a disk is physically unstable, it may need controlled imaging first. If the NAS metadata is damaged, the important details are disk order, RAID level, stripe or chunk size, file-system state and the sequence of events before the volume disappeared.

When it's worth to escalate right away

• The NAS stores company documents, accounting files, projects or backups for several people.
• There are disk errors, bad sectors, failed SMART checks or drives disappearing from the NAS.
• The problem started after an update, rebuild, migration, power failure or reset.
• Someone has already attempted a rebuild, repair or volume recovery.
• Ransomware, personal data, client data or an incident response process is involved.

What to prepare before contacting the lab

Write down the NAS model, number of drives, bay order, volume name, recent panel messages and any previous rebuild, update or reset attempt. If the device or disks are coming from outside Warsaw, use the delivery of disks from RAID/NAS to the laboratory.

If the NAS still boots, avoid new administrative changes. Take photos of messages, export logs if this can be done without repairing or rebuilding, and keep the drives in the order in which they worked in the array.

When NAS failure ceases to be an incident limited to domestic use

If the NAS holds the only copy of photos, business documentation, CCTV recordings or shared project files, the case stops being a simple convenience issue. Every extra write, rebuild or "repair" from the web interface can reduce the chance of a clean reconstruction. RAID data recovery workflow; for server media the separate path is SAS disks. In many cases, it is better to stop and consult the scenario than to accelerate the failure.
