Backing up a VPS involves more than downloading one file. A usable backup includes application data, databases, configuration and the access credentials required for recovery.
We show how to inventory backups, keep copies separate from the production server and test restores without overwriting production data.
1. Inventory the data to restore
| Data scope | Typical example |
|---|---|
| Application data | Uploads, documents and content |
| Database | A consistent export or application-specific backup |
| Configuration | Web server, application and scheduled tasks |
| Access | Keys and secrets in a secure, separately managed location |
| Installation guide | Versions, dependencies and restoration order |
2. Define retention and storage location
- How much data loss and recovery time can you accept? Set backup frequency accordingly.
- Keep at least one copy separate from the production VPS. A backup on the same disk does not protect against disk failure.
- Control access, encryption and retention; backups can contain personal data too.
- Monitor backup results and storage capacity; a schedule alone does not prove a successful backup.
3. Perform an isolated test restore
- Select a recent backup and verify that all expected parts are present.
- Restore in a test environment or separate VPS. Do not write to the production database or directory.
- Check application startup, content, permissions and key user actions.
- Measure recovery time, note missing steps and improve the backup plan.
4. Define a recovery decision point
- Decide when writes will stop so that new data is not lost during recovery.
- Preserve evidence from the affected system if an attack or compromise is suspected.
- After recovery, check services and data received since the update.
- Review the backup plan after every significant application or database change.
