SecretId：AKID8Uph
SecretKey：3rhGgpi
bucket Name: game-data-backup-125100
二：支配COS客户端

2）配置
coscmd config -a AKID8Up -s 3rhGgpi -b game-data-backup-1251 -r ap-guangzhou
三：文件夹上传
#将本地的 /data/game/redis 文件上传到 cos 的 /cats/cats-2005 路径下
coscmd upload -r /data/game/redis /cats/cats-2005
Upload /data/game/redis/id-prod/a.txt => cos://game-data-backup-1251/cats/cats-2005/id-prod/a.txt
预期目录：
coscmd upload -r /data/game/redis /cats/cats-2005/redis
Upload /data/game/redis/id-prod/a.txt => cos://game-data-backup-1251/cats/cats-2005/redis/id-prod/a.txt

四：下载指定COS文件夹
1.修正/root/.cos.conf 对应的Bucket name
2.实行下载命令
coscmd download -rf / /data/scripts/data_cos_backup/tlry-unity
3.备份到指定cos
修正.cos.conf
time coscmd upload -r /data/scripts/data_cos_backup/tlry-unity /tlry-unity --skipmd5
修正存储类型为低频
