QNAP NAS recovery in Temecula
QNAP builds NAS units for homes, studios and enterprises, from two-bay desktop models to large SAS and all-flash rack systems. Its storage design has more layers than most, which gives administrators flexibility and makes a failed QNAP harder to put back together.
QNAP systems we recover
- TS series
- Desktop and rack units running QTS, from home models to the TS-x73A and TS-x64 business ranges.
- TVS and TS-h series
- Higher-performance units, many running QuTS hero.
- TBS NASbook
- Compact all-M.2 SSD units.
- ES and enterprise ZFS NAS
- Dual-controller SAS systems.
- TR and TL expansion units
- USB and SAS enclosures attached to a NAS.
How QNAP stores data
- QTS
- Linux software RAID groups, combined into a storage pool with LVM, carrying thick, thin or static volumes formatted ext4. Thin volumes add a layer of metadata that must be intact for the data to be readable.
- QuTS hero
- ZFS pools with RAID-Z, checksums, inline compression and deduplication, and snapshots.
- Qtier and SSD cache
- Data is moved between SSD and hard drive tiers. A failed tier or cache affects the whole pool.
- Encryption
- Encrypted volumes and shared folders, and self-encrypting drives. The key or password is required.
What goes wrong
- "Storage pool error" or "RAID group inactive"
- Volume shown as unmounted or "File system not clean"
- Thin pool metadata corruption
- Second drive failure during a rebuild
- Firmware update that fails or leaves the unit unbootable
- ZFS pool that will not import
- Deleted volume, LUN or shared folder
- Unit re-initialized by mistake
- Power surge, overheating and backplane faults
QNAP and ransomware
QNAP units exposed to the internet have been targeted repeatedly, by Qlocker in 2021, DeadBolt in 2022 and several waves of eCh0raix. If your files have been renamed or locked, disconnect the NAS from the network and power it down. Do not delete anything or reset the unit. We examine the drives for snapshots, earlier file versions and data that the attack did not reach.
QNAP models we recover, 2013 to 2026
Examples of the model numbers we see most often, grouped by the years each range was sold. The model name is on the front panel and on the white label underneath or at the rear of the unit, next to the serial number.

Not listed? These are examples, not limits. If your model is missing we almost certainly still recover it. Give us the number when you start a case.
How we work
Every drive is imaged, and failed drives are repaired first. We rebuild the RAID groups, pool and volumes from the images and extract the data, including iSCSI LUNs and virtual machine files.
Label each drive with its bay number before removing it. Call RMLD on (951) 595-8065 or start a case online.
