What this page helps you understand
Backup files are often created during migrations, quick fixes, or agency handoffs, then left in the web root. Fixnx looks for common backup exposure patterns and explains which findings deserve urgent cleanup.
What this scan checks
Backup archives
.bak and .old files
Database dump clues
Config file paths
Source bundles
Sensitive file priority
Backup files can expose the data a live page protects
A website can have strong login rules and still leak data through a forgotten backup file. Archives, SQL dumps, old configs, and copied source bundles are attractive because they may bypass the application entirely.
Fixnx checks common backup naming patterns, exposed file paths, and directory clues, then prioritizes findings based on the type of data that may be inside.
Move backups outside the web root, deny risky file extensions, remove old migration artifacts, rotate exposed secrets, and rescan after cleanup to confirm the public evidence is gone.
Example Fixnx finding
Issue: Potential backup archive exposed
Risk: High
Evidence: A backup-like file path such as .bak, .old, .zip, .sql, or a source bundle appeared publicly reachable.
Recommended fix: Move backups outside the web root, block risky backup extensions, remove old artifacts, rotate exposed secrets, and rescan.
Backup files can expose source code, database content, configuration values, or credentials outside the normal application controls.
What to fix first
- Critical exposed files, admin panels, secrets, or takeover paths.
- Broken HTTPS, missing redirects, weak SSL/TLS behavior, or unsafe cookie handling.
- Confirmed injection, XSS, access-control, authentication, or sensitive API evidence.
- High-impact security headers and browser protections that reduce attack impact.
- Medium and low hardening recommendations after the risky public evidence is fixed.

FAQ
Which backup files are most risky?
Database dumps, source archives, environment files, old configuration files, and backups that may include credentials or private user data are the highest priority.
Can I keep backups on the same server?
Backups should not be reachable through the public website. Store them outside the web root, protect access, and avoid predictable public filenames.
What does Backup File Exposure Check check first?
It starts with backup archives, then reviews .bak and .old files, database dump clues, and other public signals that can be checked safely from outside the site.
Can I use Backup File Exposure Check on any website?
Only scan websites you own or have explicit permission to test. Fixnx is built for defensive security checks and website protection. Unauthorized scanning may be illegal.
Does Backup File Exposure Check prove a site is completely secure?
No. A scan reports the public evidence it collected during a bounded test. It helps you find visible risk, but it cannot guarantee that every private workflow or server-side issue is safe.
Can Fixnx help me understand how to fix the findings?
Yes. Fixnx reports include evidence, severity, confidence, and remediation guidance so owners, developers, and security teams can decide what to fix first.
