使用rclone同步文件到backblaze的教程以及rclone常用命令大全
rclone是一款开源的基于golang的文件同步工具，主要特性如下：
始终检查MD5 / SHA1哈希是否具有文件完整性 文件上保留的时间戳 基于整个文件支持部分同步 复制模式仅复制新的/更改的文件 同步（单向）模式，使目录相同 检查模式以检查文件哈希是否相等 可以与网络同步，例如可以与两个不同的云帐户同步 加密后端 缓存后端 块后端 联合后端 可选的FUSE挂载（rclone挂载） 多线程下载到本地磁盘 可以通过HTTP / WebDav / FTP / SFTP / dlna 提供本地或远程文件 基于实验Web的GUI 支持的众多的云存储平台，如OVH,onedrive,google drive等等。。。

输入上面显示的密匙ID，然后再次输入密匙
看下面代码，自行修改相关密匙和id
Account ID or Application Key ID
Enter a string value. Press Enter for the default ("").
account> 93ofsdljfksljfkdsfkdsf
Application Key

key> j39re0wr9reiw8s9pdfsjdlkfjsd
Permanently delete files on remote removal, otherwise hide files.
Enter a boolean value (true or false). Press Enter for the default ("false").
hard_delete>
Edit advanced config? (y/n)
y) Yes
n) No (default)
y/n> n
Remote config
--------------------
[testb2]
type = b2
account = 93ofsdljfksljfkdsfkdsf
key = j39re0wr9reiw8s9pdfsjdlkfjsd
--------------------
y) Yes this is OK (default)
e) Edit this remote
d) Delete this remote
y/e/d> y
测试配置是否成功
rclone ls tetb2:filename
rclone sync -v /var/www/test/ tetb2:filename/
同步本地/var/www/test/文件夹下的所有文件到backblaze存储filename目录下
并且使用了-V参数表示显示同步进度。。。
其实sync命令相当于增量更新，也就是说源文件没有的，远程存储上的所有多余的文件都会被删除
第二次执行sycn命令时只同步修改过的文件，
其它文件则跳过~~~~这样就不担心流量和backblaze每日的API限制了
这里的filename文件夹要在backblaze自行创建，否则会报错
