Website Backup Guide: How to Create a Complete Backup of Any Website

Creating a website backup is essential for disaster recovery, platform migration, and content preservation. This guide covers how to create complete website backups — including sites built with modern JavaScript frameworks.

When You Need Website Backups

• Disaster recovery — Your hosting provider goes down or data is corrupted.
• Platform migration — Moving from one CMS or hosting platform to another.
• Content archival — Preserving website content for future reference.
• Legal compliance — Regulatory requirements to maintain records of published content.
• Competitive analysis — Archiving competitor websites for reference.

Backup Methods

1. Frontend Backup (What Visitors See)

A frontend backup captures what visitors see — the rendered HTML, CSS, JavaScript, images, and fonts. Use websitedownloader.org for this. It works even for JavaScript-rendered sites.

2. CMS/Database Backup (Source Data)

If you have access to the website's CMS or database, export the source data. This preserves content in its original, editable format. Most CMSes (WordPress, Drupal, Ghost) have built-in export tools.

3. Git Repository Backup

If the website's source code is in a git repository, clone it. This preserves the build pipeline and all source files.

Best Practices

• Automate backups — Don't rely on manual backups. Use the websnap CLI with cron jobs.
• Multiple backup types — Combine frontend and database backups for completeness.
• Test restores — Regularly verify that your backups can actually be restored.
• Version your backups — Keep multiple dated backups, not just the latest.
• Store offsite — Keep backups in a different location than the original website.
