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.
