== Description ==

**Trinity Backup** is a powerful, fast, and reliable WordPress backup, migration, and restore plugin. It is built to work smoothly on any hosting — including shared hosting with strict PHP limits, timeouts, and low memory.

Whether you need to create a full site backup, migrate WordPress to a new domain, clone a staging site to production, or schedule automatic daily backups — Trinity Backup handles it all without breaking a sweat.

### Why Choose Trinity Backup?

Most backup plugins fail on large sites because of PHP timeouts, memory limits, and upload restrictions. Trinity Backup solves all of that:

* **Zero timeouts** — Processes everything in safe, resumable AJAX chunks. Even if the browser is closed, you can continue where you left off.
* **Ultra-low memory usage** — Uses streaming archive technology instead of loading files into RAM. Works on hosts with 64 MB memory limits.
* **Any site size** — Designed for sites with thousands of posts, large media libraries, and massive databases.
* **Resumable operations** — Automatically resumes after interruptions, browser refreshes, or temporary server issues.
* **Single-file archives** — Each backup is one `.trinity` file that contains your entire site: database, plugins, themes, uploads, and all wp-content.

### Full Site Backup & Export

Create a complete backup of your WordPress site with one click. The exported `.trinity` archive contains everything needed to fully restore or migrate your site:

* **Database export** — All tables including posts, pages, users, options, WooCommerce orders, custom post types, and any custom tables.
* **Files export** — All files in wp-content: plugins, themes, uploads, mu-plugins, and custom directories.
* **Selective backup** — Choose exactly what to include or exclude: media uploads, plugins, themes, database, spam comments.
* **Auto-download** — Automatically downloads the backup file to your computer after creation.
* **Real-time progress** — Visual progress bar and detailed log showing every step of the backup process.

### One-Click Migration & Restore

Move your WordPress site to a new host, new domain, or new server with zero hassle:

* **Automatic URL replacement** — Intelligently replaces all old URLs with new ones across the entire database, including serialized data in options, widgets, and page builders.
* **Serialized data safe** — Properly handles serialized PHP data (used by most themes and plugins) so nothing breaks after migration.
* **Drag & drop import** — Simply drag your `.trinity` file into the import area or click to browse. No FTP, no phpMyAdmin, no command line needed.
* **Cross-host compatible** — Works across any hosting provider: cPanel, Plesk, LocalWP, Flywheel, SiteGround, Bluehost, GoDaddy, Cloudways, AWS, and more.
* **Local ↔ Live** — Perfect for moving sites between local development environments (LocalWP, MAMP, XAMPP, Laragon) and live servers.

### Backup Management Dashboard

A clean, modern dashboard to manage all your backups:

* **Backup list** — View all existing backups with filename, size, creation date, and who created them.
* **Bulk actions** — Delete individual backups, delete all backups at once, or clean up incomplete temporary files.
* **Refresh** — Instantly refresh the backup list without reloading the page.
* **Responsive design** — Clean, card-based layout that works great on any screen size.

### Dark Mode & Light Mode

Trinity Backup includes a beautiful, modern UI with full theme support:

* **Light theme** — Clean white design that matches the default WordPress admin.
* **Dark theme** — Eye-friendly dark appearance for comfortable use in low-light environments.
* **Auto theme** — Automatically follows your operating system's light/dark preference.
* **Instant switching** — Change theme with one click, no page reload needed. Your preference is saved per user.

### AES-256-GCM Encryption (Pro)

Protect your backups with military-grade encryption:

* **AES-256-GCM** — The same encryption standard used by banks. Your backup data is fully encrypted at rest.
* **Password protection** — Set a password when creating a backup. The same password is required for import.
* **Secure key derivation** — Uses proper cryptographic key derivation to turn your password into an encryption key.
* **Streaming encryption** — Files are encrypted in chunks during backup, keeping memory usage low even for encrypted backups.

### Scheduled Backups (Pro)

Automate your backup routine with flexible scheduling powered by WordPress Cron:

* **Multiple frequencies** — Hourly, every 2/4/6/12 hours, daily, or weekly.
* **Custom time selection** — Choose the exact hour when daily or weekly backups should run.
* **Backup retention** — Automatically delete old scheduled backups. Keep the last 1–10 backups and save disk space.
* **Next run display** — See exactly when the next scheduled backup will run.
* **Reliable execution** — Uses WordPress Cron with automatic rescheduling if a run is missed.
* **Exclude content** — Customize what each scheduled backup includes: skip media, plugins, themes, database, or spam comments.

### Pre-Update Backups (Pro)

Never lose your site to a bad update again. Trinity Backup can automatically create a full backup before any WordPress update:

* **Plugin updates** — Automatic backup before installing plugin updates, including bulk updates.
* **Theme updates** — Automatic backup before theme updates.
* **Core updates** — Automatic backup before WordPress core updates.
* **Block failed backups** — Optionally prevent the update from proceeding if the pre-update backup fails. Recommended for maximum safety.
* **Single backup per batch** — Bulk updates create only one backup per update run, saving disk space and time.
* **Selective content** — Exclude media, themes, plugins, database, or spam comments from pre-update backups.

### Email Notifications (Pro)

Stay informed about every backup operation without checking the dashboard:

* **Success & failure alerts** — Get notified when backups complete successfully or when they fail.
* **Multiple recipients** — Send notifications to multiple email addresses (comma-separated).
* **Event filtering** — Choose which events to be notified about: manual backups, scheduled backups, pre-update backups, and imports/restores.
* **Failure-only mode** — Option to only receive emails when something goes wrong — no noise when everything is OK.
* **Test email** — Send a test email to verify your configuration works with a single click.
* **HTML emails** — Professional, well-formatted HTML email notifications with backup details.

### WP-CLI Support (Pro)

Full command-line interface for developers, agencies, and automated deployment pipelines:

* **wp trinity export** — Create backups from the command line with all export options (exclude media, plugins, themes, database, spam).
* **wp trinity import** — Restore from a `.trinity` archive file by specifying the path.
* **wp trinity list** — List all existing backups with size and date.
* **wp trinity delete** — Delete a specific backup by ID.
* **wp trinity schedule** — Configure scheduled backups (frequency, time, retention) from the terminal.
* **Encrypted CLI backups** — Pass `--password=secret` to create encrypted backups via CLI.
* **CI/CD ready** — Integrate Trinity Backup into your GitHub Actions, GitLab CI, Bitbucket Pipelines, or custom deployment scripts.

### White Label (Pro)

Fully rebrand the plugin for client sites or your own SaaS product:

* **Custom plugin name** — Replace "Trinity Backup" with your own brand name in the admin menu, page header, and plugins list.
* **Custom description** — Set a custom subtitle/description displayed on the plugin page.
* **Custom author** — Replace the author name and URL on the plugins list page.
* **Custom menu icon** — Use any Dashicon class or a custom image URL as the admin menu icon.
* **Hide branding** — Remove the Trinity Backup logo from the page header.
* **Hide submenus** — Selectively hide "Account" and "Contact Us" submenu items.
* **Hide plugin actions** — Hide "View details" on the plugins page, or keep only the "Deactivate" link.
* **Access control** — Restrict White Label settings access to a specific administrator. Other admins won't even see the settings section.
* **Persistent settings** — All White Label settings survive plugin updates.

### Flexible Export Options

Fine-tune every backup with granular exclusion options:

* **Exclude media uploads** — Skip the wp-content/uploads folder to create smaller backups.
* **Exclude plugins** — Skip the plugins directory if you only need themes and content.
* **Exclude themes** — Skip the themes directory.
* **Exclude database** — Create a files-only backup without the database.
* **Exclude spam comments** — Keep your backups clean by skipping spam comment data.
