OS Overwrite Recovery: AR Gold Mumbai
AR Gold · Mumbai · Jewellery manufacturer · 501–1,000 employees · Active retainer client since incident · 2024
What happened
AR Gold runs ERPNext on a Linux server. 500-plus employees across their jewellery manufacturing operations depend on it daily. In 2024, the server stopped booting. The in-house IT contact diagnosed it as an OS failure and initiated a fresh OS reinstall on top of the broken system. It made things worse. The reinstall overwrote the existing OS and its data.
The call came in at 9pm. Arun was onsite by 11pm.
What was done — and why the order mattered
The first action onsite was not recovery. Before touching the system, Arun used TestDisk to clone the entire disk image sector by sector to an external drive. That clone ran through the night. It meant the disk state at the moment of arrival was preserved exactly, regardless of what the repair required.
With the image secured, the repair was methodical. The overwritten OS boot sequence was recovered — kernel and initramfs extracted and repaired using a working equivalent. The server booted. ERPNext, Frappe, and the MariaDB database were intact. The actual repair took a few minutes once the disk was safe.
Operations were restored before the first shift the following morning. No production day was lost.
Clone the disk before you touch anything. That one decision is what made the repair reversible.

What it cost — and what it would have cost
Emergency OS recovery of this type — same-night onsite, full disk clone, boot sequence repair on a live production ERP server — carries a market rate of Rs.75,000 to Rs.1,50,000. The work was verified. Fees paid on record.
A monthly retainer at Rs.15,000 would have caught the disk condition weeks earlier. The incident would not have happened.
After the incident
AR Gold became an active monthly retainer client after the incident. Monitoring, backup verification, and regular patching are now in place. The conditions that allowed the original failure to go undetected do not exist on a managed server.
