Linux folder backup script

Here is my script I use to backup a linux folder, firstly it mounts the backup drive and checks to see if it has mounted by reading a file named NOT_MOUNTED created by using

touch NOT_MOUNTED

Then using rsync it copies only new and modified files to the backup drive and excludes all .* files, this is to stop the backing up folders like the .Trash folder. It also creates and appends a log file stored in $LOGDIR.

Add as a cron job by:

crontab -e
add @daily /root/{filename} <-- name of script

Remember to change the file to make it executable

chmod +x {filename}

Usage:

$LOGDIR = log file
$SOURCE DIR =Source directory
$DESTDIR = Destination directory

# Backup SH file by Chris Hawkins
# Get date and time
DATETIME=$(date)
LOGDIR=/usr/log
SOURCEDIR=/home
DESTDIR=/backup
mount $DESTDIR

if [ -f $DESTDIR/NOT_MOUNTED ];
then

LOGMESSAGE='Backup NOT Mounted (ERROR) - Backup NOT completed'

echo $DATETIME $LOGMESSAGE >>$LOGDIR/backuplog

else

LOGMESSAGE='Backup Started'

echo $DATETIME $LOGMESSAGE >>$LOGDIR/backuplog

rsync -auqlP --delete --exclude='.*' $SOURCEDIR $DESTDIR
# Get date and time
DATETIME=$(date)
LOGMESSAGE='Backup Completed'
echo $DATETIME $LOGMESSAGE >>$LOGDIR/backuplog

fi

cd $LOGDIR
umount $DESTDIR
