## 背景
– 企业规模：中型企业，约500名员工
– 数据量：当前约20TB，年增长率20%
– 备份策略：每周全备份，每天增量备份
– 保留期限：全备份保留4周，增量备份保留7天

## 容量计算
# 全备份存储需求
FULL_SIZE=$((20 * 1024 / 2)) # 2:1压缩率
FULL_TOTAL=$((FULL_SIZE * 4))

# 增量备份存储需求
INCR_SIZE=$((20 * 1024 * 5 / 100 / 2)) # 5%日变化率
INCR_TOTAL=$((INCR_SIZE * 7))

# 总存储需求
TOTAL_SIZE=$(((FULL_TOTAL + INCR_TOTAL) * 120 / 100)) # 20%额外空间

echo “全备份大小：${FULL_SIZE} GB”
echo “全备份总需求：${FULL_TOTAL} GB”
echo “增量备份大小：${INCR_SIZE} GB”
echo “增量备份总需求：${INCR_TOTAL} GB”
echo “总存储需求：${TOTAL_SIZE} GB”

# 示例输出
全备份大小：10240 GB
全备份总需求：40960 GB
增量备份大小：512 GB
增量备份总需求：3584 GB
总存储需求：53453 GB

## 实施建议
1. 配置主磁盘池：30TB，启用重复数据删除和压缩
2. 配置次磁盘池：20TB，用于存储较旧的备份数据
3. 配置磁带库：用于长期归档，存储保留期超过30天的备份
4. 实施存储生命周期管理，自动将数据从磁盘迁移到磁带
5. 定期监控存储容量，设置80%使用率预警
