Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads cloud-backup automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

rclone 通用工具
配置
# 交互式配置
rclone config
# 配置文件 ~/.config/rclone/rclone.conf
[s3]

# 加密备份
rclone sync /backup crypt:backups
常见场景
场景 1：自动备份脚本
#!/bin/bash
DATE=$(date +%Y%m%d)
BACKUP_DIR="/backup"
S3_BUCKET="s3://my-bucket/backups"
# 创建备份
tar -czvf ${BACKUP_DIR}/backup_${DATE}.tar.gz /data
# 上传到 S3
aws s3 cp ${BACKUP_DIR}/backup_${DATE}.tar.gz ${S3_BUCKET}/
# 清理本地
find ${BACKUP_DIR} -name "backup_*.tar.gz" -mtime +7 -delete
# 验证
aws s3 ls ${S3_BUCKET}/backup_${DATE}.tar.gz
场景 2：数据库云备份
#!/bin/bash
# MySQL 备份到 S3
mysqldump -u root -p database | gzip | \
aws s3 cp - s3://my-bucket/mysql/backup_$(date +%Y%m%d).sql.gz
# PostgreSQL 备份到 S3
pg_dump database | gzip | \
aws s3 cp - s3://my-bucket/postgres/backup_$(date +%Y%m%d).sql.gz
场景 3：增量同步
#!/bin/bash
# 使用 aws s3 sync 增量同步
aws s3 sync /data s3://my-bucket/data/ \
--exclude "*.tmp" \
--delete
# 使用 rclone
rclone sync /data remote:bucket/data --progress
场景 4：灾备复制
# 跨区域复制配置

成本优化
| 存储类型 | 适用场景 | 成本 |
|---|---|---|
| Standard | 频繁访问 | 高 |
| IA | 月访问 | 中 |
| Glacier | 年访问 | 低 |
| Deep Archive | 归档 | 最低 |
故障排查
| 问题 | 排查方法 |
|---|---|
| 上传失败 | 检查权限、网络、大小限制 |
| 同步慢 | 使用多线程、分片上传 |
| 成本高 | 检查存储类型、生命周期 |
| 恢复慢 | Glacier 需要先解冻 |
# 检查 S3 权限
aws s3api get-bucket-policy --bucket my-bucket
# 检查上传状态
aws s3api list-multipart-uploads --bucket my-bucket
# Glacier 解冻
aws s3api restore-object \
--bucket my-bucket \
--key backups/archive.tar.gz \
--restore-request '{"Days":7,"GlacierJobParameters":{"Tier":"Standard"}}'

Which AI agents can use cloud-backup?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is cloud-backup safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
