bash script calling rdiff-backup never ends

Question

I want to run rdiff-backup and then switch of the raspberrypi it was running on. I use the following script:

#!/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

The log file looks good (for the rdiff-backup part):

The backup is working, but then the script ends right there. rdiff-backup.log contains the full report of rdiff-backup. But neither the line "rdiff-backup end", nor the output of "df -h".

How can I make it ran to the end?

Thanks for your answers

I finally found a workaround, that solves my problem.

My sciprt which is called after booting from /etc/init.d is calling the other script which does the actual work (i.e. backup my data, and write the log file) as a background task.

/etc/init.d/CallAfterBoot.sh

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

/home/me/DoBackup.sh is the script I posted above which is now runing correctly.

Same script running as the same user now behaves differently. There's got to be some bug somewhere, however, it works for me now.
