bash脚本调用rdiff-backup永不结束

问题描述：

我想运行rdiff-backup，然后切换运行的raspberrypi。我使用下面的脚本：bash脚本调用rdiff-backup永不结束

#!/bin/sh 

date > /home/mik/rdiff-backup.log 
echo "rsync start" >> /home/mik/rdiff-backup.log 
rdiff-backup -v5 --print-statistics [email protected]::/srv/backup /srv/datenserverBackup/backup >> /home/mik/rdiff-backup.log 2>&1 

sync 
date >> /home/mik/rdiff-backup.log 
echo "rdiff-backup end" >> /home/mik/rdiff-backup.log 
df -h >> /home/mik/rdiff-backup.log 

sync 
halt

日志文件看起来不错（用于rdiff进行备份部分）：

备份工作，但随后的脚本结束就在那里。 rdiff-backup.log包含rdiff-backup的完整报告。但既不是“rdiff-backup结束”行，也不是“df -h”的输出。

我该如何让它跑到最后？

谢谢您的回答

我终于找到了一个解决办法，能解决我的问题。

从/etc/init.d启动后调用的sciprt正在调用另一个执行实际工作（即备份我的数据并写入日志文件）的脚本作为后台任务。

/etc/init.d/CallAfterBoot.sh

#!/bin/sh 
sleep 30 
/home/me/DoBackup.sh &   # '&' starts the script in background

/home/me/DoBackup.sh是我贴上面这是目前乳宁正确的脚本。

现在以相同用户身份运行的相同脚本的行为不同。但是，在某个地方肯定会出现一些错误，但现在它对我有用。
