# 📦 Ancient-Backup — v1.4.3 ## 🚀 Overview **Ancient-Backup v1.4.3** is a fully asynchronous, performance-aware backup solution for Minecraft **1.20+** servers, designed to create **complete server backups** while remaining **lag-free**, **memory-safe**, and **highly configurable**. This release focuses heavily on **memory control**, **stability**, and **production-readiness**, while offering advanced upload destinations and detailed monitoring. --- ## 🧠 Performance & Memory Management - Added a **soft memory budget system** to prevent excessive RAM usage. - ZIP and upload buffers dynamically scale based on available memory. - Automatic **best-effort garbage collection after ZIP creation** when memory pressure is detected. - Memory is also cleaned up after uploads finish. - Prevents memory from continuously growing during large backups. - Designed to respect server load and avoid TPS drops. ### New `performance` config options: - `max-memory-mb` - `max-buffer-kb` - `min-buffer-kb` - `max-chunk-mb` - `cleanup-after-backup` - `gc-after-zip` > ⚠️ **Note:** Java plugins cannot hard-limit JVM memory per plugin. Ancient-Backup enforces **soft limits** by reducing buffers, chunk sizes, and parallelism. --- ## ☁️ Backup Destinations Supports secure, encrypted uploads to: - **SFTP** - **FTPS (Explicit & Implicit TLS)** - **Microsoft Graph** - OneDrive - SharePoint - **Google Drive** ### Upload Features - Parallel uploads (configurable). - Automatic remote folder creation. - Upload speed tracking (MB/s). - Destination-side **retention policy** (old backups are removed remotely). - Ability to **retry uploading the last local backup** if a previous upload failed. - Local backup is automatically deleted after a successful upload. --- ## 📊 Monitoring & Feedback - `/abackup status` shows: - ZIP progress (%) - Upload progress (%) - Current upload speed (MB/s) - Live upload speed updates in the **server console** (updated continuously). - No in-game spam. - Permission-based notifications for staff/admins. --- ## ⏱ Scheduling & Automation - Fully automatic scheduled backups. - Manual backup start and cancel commands. - Graceful cancellation during ZIP or upload phases. - Automatically adapts resource usage based on server load. --- ## 🔔 Notifications - **Discord Webhook support** - Backup start - ZIP completed - Upload start - Upload completed - Failure - Cancellation - Fully configurable per event. - Custom username and avatar support. --- ## 🛠 Fixes & Stability Improvements - Fixed multiple compilation issues from earlier builds. - Fixed duplicated memory tracking methods. - Fixed GraphUploader initialization bugs. - Improved internal memory accounting accuracy. - Improved config reload reliability. - Ensured all upload options are **disabled by default**. --- ## 🧩 Compatibility - Minecraft **1.20+** - Java **21** - Paper / Spigot compatible - Gradle-based build --- ## 🔒 Design Philosophy Ancient-Backup is built to: - Never block the main server thread. - Avoid lag at all costs. - Prefer slightly slower backups over server instability. - Clean up all resources after each run. - Be safe for large, long-running production servers. --- ## 📌 Recommended Configuration (Example) ```yml performance: max-memory-mb: 512 max-buffer-kb: 8192 min-buffer-kb: 256 max-chunk-mb: 16 cleanup-after-backup: true gc-after-zip: true
