Description
Trinity Backup is a fast, reliable backup, migration, and restore plugin built to work smoothly on real-world hosting — including shared hosting with strict limits.
Bypass common hosting limits
Most backup plugins fail because of timeouts, memory limits, and large files. Trinity Backup is built differently:
- No timeouts – Runs in safe, resumable chunks via AJAX
- Low memory usage – Uses streaming archives instead of loading everything into memory
- Any-size sites – Designed for big sites (as long as you have enough disk space)
- Resumable – Continue after refresh, logout, or temporary interruptions
Made for migration
Move a site to a new host or domain with confidence:
- Automatic URL replacement in the database and serialized data
- One-click restore from a single backup archive
Security (optional)
- AES‑256‑GCM encryption – Protect backups with a password
