Overview


This guide covers how to physically extract database files from a client's PC when the machine is failing or the database service cannot start, so that data can be saved to a USB drive and restored on a working machine.

There are two possible situations when you arrive at a client site:

Situation What it means Procedure
A — Windows boots, but the DB service won't start You can navigate the file system normally Go directly to Part A
B — Windows does not boot at all You need a live Linux USB to access the drive Go to Part B first, then follow the extraction steps

What to Bring

Before going on-site, make sure you have:

  • A USB drive with enough space (at least as large as the client's database, ideally 2x).
  • A bootable Linux live USB (Ubuntu LTS recommended) — only needed if the PC doesn't boot.
  • This guide, either printed or on your phone.
