bash腳本調用rdiff-backup永不結束

Question

我想運行rdiff-backup，然後切換運行的raspberrypi。 我使用下面的腳本：

#!/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 

日誌文件看起來不錯（用於rdiff進行備份部分）：

備份工作，但隨後的腳本結束就在那裏。 rdiff-backup.log包含rdiff-backup的完整報告。但既不是「rdiff-backup結束」行，也不是「df -h」的輸出。

我該如何讓它跑到最後？

謝謝您的回答

我終於找到了一個解決辦法，能解決我的問題。

從/etc/init.d啓動後調用的sciprt正在調用另一個執行實際工作（即備份我的數據並寫入日誌文件）的腳本作爲後臺任務。

/etc/init.d/CallAfterBoot.sh

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

/home/me/DoBackup.sh是我貼上面這是目前乳寧正確的腳本。

現在以相同用戶身份運行的相同腳本的行爲不同。但是，在某個地方肯定會出現一些錯誤，但現在它對我有用。
