    ### Uberspace Backup-Script by SIRprise
    ## merge of 
    ## https://www.gehaxelt.in/blog/ueberspace-backupscript/ 
    ## and
    ## https://sebastian-doering.net/linux/vollstaendiges-uberspace-backup/
    ## because the first one does not backup home and the second creates an empty www folder

    ## Version 0.9

    ## ---------------------------
    ## This is the first script:

    ## Variables
    #USER='MyUsername' #Uberspacename <- should be already set in $USER by environment
    DATE=$(date +%Y-%m-%d-%H%M%S) #Current time
    BACKUP_DIR="$HOME/Backup"
    ## END Variables

    ##Check if backup folder exists and create it
    if [ ! -d $BACKUP_DIR ]
        then
            mkdir $BACKUP_DIR
        echo "Backup-folder created"
    fi
    ##END Check

    ##Check if backup file exists and exit
    if [ -f $BACKUP_DIR/backup-$DATE.tar.bz2 ]
        then
            echo "Backup already exists"
        exit 1
    fi
    ##END Check

    ##Backup
    ##mysqldump --defaults-file=$HOME/.my.cnf --user=$USER --compact --comments --dump-date --quick --all-databases | gzip > "/var/www/virtual/"$USER"/database.sql.gz"
    mysqldump --defaults-file=$HOME/.my.cnf --user=$USER --compact --comments --dump-date --quick --all-databases | gzip > "$BACKUP_DIR/MySQL_Backup.sql"
    ##cd /var/www/virtual/$USER
    ##tar -cjf $BACKUP_DIR/www-backup-$DATE.tar.bz2 /var/www/virtual/$USER
    cd /home/$USER
    tar -cjf $BACKUP_DIR/backup-$DATE.tar.bz2 --exclude='backup*.tar.bz2' /var/www/virtual/$USER . *
    ##rm /var/www/virtual/$USER/database.sql.gz
    rm "$BACKUP_DIR/MySQL_Backup.sql"
    ##END Backup

    ## ---------------------------

    ##SOURCE="$HOME /var/www/virtual/$USER/html"
    ##mysqldump --all-databases > $BACKUP_DIR/MySQL_Backup.sql
    ## tar -cjpf $BACKUP_DIR/Backup.tar.bz2 $SOURCE --exclude="$BACKUP_DIR" --exclude="$HOME/tmp"
