我想运行 rdiff-backup 然后切换它正在运行的树莓派。我使用以下脚本：

#!/bin/sh

date > /home/mik/rdiff-backup.log
echo "rsync start" >> /home/mik/rdiff-backup.log
rdiff-backup -v5 --print-statistics offlinebackup@server::/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（对于 rdiff-backup 部分）：

备份正在工作，但脚本就在那里结束。rdiff-backup.log 包含 rdiff-backup 的完整报告。但是“rdiff-backup end”行和“df -h”的输出都不是。

我怎样才能让它跑到最后？

感谢您的回答

我终于找到了一种解决方法，可以解决我的问题。

从 /etc/init.d 启动后调用的我的 sciprt 正在调用另一个执行实际工作的脚本（即备份我的数据，并写入日志文件）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 是我在上面发布的脚本，现在可以正常运行。

以相同用户身份运行的相同脚本现在表现不同。某处一定有一些错误，但是，它现在对我有用。
