I wrote just a small script, which creates a backup copy on the
server, when a file is created or changed.
Next I am writing a start/stop script for /etc/init.d
Also a cron job should delete all files older than 30 days from the
backup directory.
#!/bin/sh
WATCH=/var/simias/data/simias/SimiasFiles
BACKUP=/srv/backup/SimiasFiles
inotifywait -mr --exclude '\.simias\.wf\.' --format "%w%f" -e
close_write $WATCH |
while read source
do
if [ -d "${source}" ]
then
continue
fi
# convert absolute path to relative
buffer=`echo "${source}" | sed 's_'$WATCH'/__'`
# echo "${buffer}"
# destination
destination="$BACKUP/${buffer}"
# directory: everything before last '/'
directory="${destination%/*}"
# echo "${directory}"
# create directory
if [ ! -d "${directory}" ]
then
# echo "mkdir -p ${directory}"
mkdir -p "${directory}"
fi
# if destination not exists, just copy the file
if [ ! -e "${destination}" ]
then
echo "cp ${source} ${destination}"
cp "${source}" "${destination}"
continue
fi
echo "${destination} exists"
# if destination is not equal to source
cmp --silent "${source}" "${destination}"
if [ $? -eq 0 ]
then
echo "${destination} is the same"
continue
fi
echo "${destination} needs to be copied"
# create new filename: basename + datetime + number: filename!
yyyymmdd-hhmmss!1
destinationnew="${destination}!$(date +%Y%m%d-%H%M%S)"
if [ -e "${destinationnew}" ]
then
$i=1
while [ -e "${destinationnew}!$i" ]
do
(($i++))
done
fi
# rename existing file to new name
echo "mv ${destination} ${destinationnew}"
mv "${destination}" "${destinationnew}"
# copy the file
echo "cp ${source} ${destination}"
cp "${source}" "${destination}"
done
