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. ---Overview
- 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.Performance & Memory Management
New
-performanceconfig 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.
Supports secure, encrypted uploads to: - SFTP - FTPS (Explicit & Implicit TLS) - Microsoft Graph - OneDrive - SharePoint - Google DriveBackup Destinations
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 statusshows: - 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. ---
- 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. ---Scheduling & Automation
- Discord Webhook support - Backup start - ZIP completed - Upload start - Upload completed - Failure - Cancellation - Fully configurable per event. - Custom username and avatar support. ---Notifications
- 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. ---Fixes & Stability Improvements
- Minecraft 1.20+ - Java 21 - Paper / Spigot compatible - Gradle-based build ---Compatibility
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. ---Design Philosophy
