NAS Enclosure Failure — Retail Group, Sharjah
The Situation
A power surge caused the NAS controller board to fail. Two of the four drives were also affected by the surge. The client had not maintained an off-site backup and required access to three years of financial records and stock data.
The Challenge
The controller failure had corrupted the volume metadata, and the two surge-affected drives had developed bad sector clusters in the file system area. The Btrfs file system required specialist reconstruction tools.
Our Approach
All four drives were imaged independently. The two surge-affected drives were treated with targeted sector recovery passes. Volume metadata was reconstructed manually from the imaged copies, and the Btrfs file system was rebuilt in a virtual environment.
The Outcome
Full recovery of all financial records, stock databases, and operational documents. The client was back in operation within four days.
