PlayerInvBackup

中文说明

Paper / Folia 1.21.1+ player backup plugin, PlayerInvBackup stores player inventory, armor, offhand, ender chest, and experience, then provides GUI and command tools for browsing, claiming, exporting, and restoring backups

🔂 Features

• Automatic backups by timer and by player events: join, quit, death, and world change
• Manual self backup, manual target backup, and one-by-one batch backup for all online players
• Backup scope includes inventory storage, hotbar, armor, offhand, ender chest, and experience
• Purpur expanded ender chest support: automatically detects 9-54 ender chest slots and works with six-rows and use-permissions-for-rows
• GUI backup list with pagination, time filters, trigger filters, backup ID search, date/time range search, refresh, and fast page jumps
• GUI backup preview with inventory / ender chest switching, slot claiming, restore confirmation, standalone experience restore, pending delivery, pin toggle, shulker export, and teleport to backup location
• Shulker export for the current preview view, with separate inventory and ender chest exports
• Pending-delivery queue for items that cannot fit into the operator's inventory during claiming
• Pinned backups and notes; pinned backups are listed first and excluded from automatic cleanup
• SHA-256 snapshot verification and pre-restore safety backup before restore
• Incompatible item protection for claiming, exporting, and restoring old or cross-version data
• Audit logs for sensitive operations such as backup, restore, slot claim, pending delivery, pin, note, and shulker export
• Asynchronous GitHub Releases update checker with console and administrator join reminders
• Storage backends: SQLite, Local, MySQL, PostgreSQL, and H2
• Bukkit native GUI and optional ProtocolLib packet GUI with automatic fallback
• Configurable GUI sounds, language files, time filters, retention, queue limits, and shulker box material
• bStats support

🌋 Runtime

• Java 21+
• Paper API 1.21
• Recommended server version: Paper / Folia 1.21.1+
• Optional dependency: ProtocolLib

ProtocolLib is only used for packet GUI mode; if it is not installed, the plugin still works and falls back to Bukkit native GUI automatically

🛡️ Data Safety

• Backups store a SHA-256 hash and restore verifies the snapshot before applying it
• Restore creates a pre-restore safety backup first; if that safety backup fails, restore is cancelled
• Restoring inventory and ender chest overwrites the target player's current inventory and ender chest
• Standalone experience restore only overwrites the target player's level, total experience, and progress
• Claimed slots are excluded from restore
• Pinned backups and backups with undelivered items are excluded from automatic cleanup
• Incompatible items are blocked or skipped depending on the operation and config

🧾 Audit

Audit records administrator-sensitive operations for later review and troubleshooting

• Records actor, target, backup ID, action type, and operation details
• Covers manual backup, batch backup, restore, slot claim, pending delivery, pin, note, and shulker export
• Can also print audit entries to console
• Supports automatic retention cleanup
