Common questions
Can you recover data from a failed QNAP TS-x20, TS-x21, TS-x31 & TS-x33 (ARM)?
In most cases, yes. Arrays are reconstructed from drive images on our own systems, including SHR, Btrfs, XFS, ZFS and proprietary layouts, so your shares come back intact.
Where do I find my NAS model number?
The model name is on the front or rear label of the unit, for example DS920+ or TS-453D.
How long does a recovery take?
Straightforward cases take a few days; clean-room and RAID work can take longer.
