Linux AppImage 备份与恢复指南
一 基础备份与恢复
cp /path/to/YourApp.AppImage /path/to/backup/ls -l /path/to/backup/YourApp.AppImage~/Applications/):cp /path/to/backup/YourApp.AppImage ~/Applications/chmod +x ~/Applications/YourApp.AppImage./YourApp.AppImage 或双击执行二 打包与校验增强
tar -czvf app_backup.tar.gz /path/to/YourApp.AppImagetar -xzvf app_backup.tar.gz -C /path/to/destination/md5sum YourApp.AppImage,备份时一并保存校验文件md5sum -c YourApp.AppImage.md5,输出 OK 表示一致backup_appimage.sh:#!/usr/bin/env bash
BACKUP_DIR="$HOME/AppImageBackups/$(date +%F_%H-%M-%S)"
mkdir -p "$BACKUP_DIR"
cp "$1" "$BACKUP_DIR/"
md5sum "$1" > "$BACKUP_DIR/$(basename "$1").md5"
echo "已备份至 $BACKUP_DIR"
chmod +x backup_appimage.sh0 3 * * * /path/to/backup_appimage.sh /path/to/YourApp.AppImage三 使用 AppImageLauncher 的集成备份与灾难恢复
~/.local/share/applications/~/.local/share/icons/~/.config/appimagelauncher/~/Applications/~/Applications/update-desktop-database ~/.local/share/applications#!/usr/bin/env bash
BACKUP_DIR="$HOME/.ail_backups/$(date +%Y%m%d_%H%M%S)"
mkdir -p "$BACKUP_DIR"
cp -r ~/.config/appimagelauncher "$BACKUP_DIR/config"
cp ~/.local/share/applications/*.desktop "$BACKUP_DIR/desktop_files/" 2>/dev/null || true
find ~/Applications -name "*.AppImage" -exec sh -c '
for f; do echo "$f: $(md5sum \"$f\" | cut -d\" \" -f1)"; done
' sh {} + > "$BACKUP_DIR/appimage_manifest.txt"
# 保留最近10个备份
ls -tp ~/.ail_backups | grep -v '/$' | tail -n +11 | xargs -I {} rm -rf ~/.ail_backups/{}

chmod +x YourApp.AppImage./YourApp.AppImagesudo apt update && sudo apt install libfuse2--appimage-extract-and-run 参数运行(解压到临时目录后执行,不依赖 FUSE).desktop 文件并刷新菜单:[Desktop Entry]
