详情介绍:
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
.trinityfile that contains your entire site: database, plugins, themes, uploads, and all wp-content.
.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.
- 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
.trinityfile 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.
