How can I stop rsync from deleting data if network link is dropped?
 

I run rsync as a cron job on a Slackware 9 box. I use smbmount to mount a Windows share and then sync data using rsync with the --delete switch. Sometimes the connection drops while rsync is still running, resulting in the rest of the data being deleted. Is there a way of stopping this to happen? My script looks like this:

umount /mnt/new_projects
smbmount //192.168.0.12/repl /mnt/new_projects -o username=tux%penquin
if [ $? = 0 ]
then
rsync -a -t -r -u -z \
--modify-window=10 \
--ignore-errors \
-v --progress \
--timeout=0 \
--stats \
--delete \
--include "*/" \
--include "*.par" \
--include "*.asm" \
--include "*.cfg" \
--exclude "*" \
--exclude "Visualization/" \
/mnt/new_projects/ "/disk1/Projects"
umount /mnt/new_projects
chmod -R 777 /disk1/Projects
echo Finished at &date
exit 1
else
echo "Could not mount $sharename on $ip"
echo "Rsync did not transfer any data at this time."
exit 1
fi

How about --delete-after

Thanks. I read up on it, but many people seems to have a problem with it. However, I will try it on my side and see what it does.
