我正在编写一个脚本，用于使用 rsync 从 server-a 到 server-b 自动复制文件，这是我的脚本：
#!/bin/bash
NOW=$(date +"%Y-%m")
rsync -au --ignore-existing /var/www/uploads/$NOW/* -e root@1.1.2.2:/var/www/uploads/$NOW/.
当我们下个月（例如从 10 月到 11 月）时，我的脚本出现此错误：
`
rsync: mkdir "/var/www/uploads/2014-11/." failed: No such file or directory (2)
rsync error: error in file IO (code 11) at main.c(605) [Receiver=3.0.9]
rsync: connection unexpectedly closed (9 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(605) [sender=3.0.9]
`我应该如何解决这个错误？请帮我
