##### ---DICHIARAZIONE  VARIABILI GLOBALI---
##### variabili non dipendenti dal contatore

mount_dir="/mnt/backup"
log_dir="/var/log/backup/mailbox"
dest_dir="$mount_dir/mailbox"
count_file="$dest_dir/zzcount.dat"
fecha=`date +"%Y-%m-%d"`

check_file="$mount_dir/check.dat"

##### NOTIFICHE EMAIL
hostserver="mx.hostname.dominio"
emailfrom="admin@mx.hostname.dominio"
emaildest=( admin@mx.hostname.dominio email@example.com )

##### EVENTUALI MOUNT
# mount -t cifs \\[ip NAS]\[nome condivisione] -o username=[username],password=[password] $mount_dir

##### VERIFICA DI AVVENUTO MOUNT NELL'AREA PREPOSTA AI BACKUP
##### PROCEDURA CHECK FILE
if [ -f $check_file ];
then
  # file esiste, area mount ok
  # nulla da notificare
  echo ""
else
  # file NON esiste, area mount ERRATA
  # notifica ed esci
  # INVIO E-MAIL DI NOTIFICA CON IN ALLEGATO IL LOG-FILE PRODOTTO

##### VERIFICA CARTELLE DI DESTINAZIONE
if [ -d $dest_dir ];

##### PROCEDURA CONTATORE
if [ -f $count_file ];
then
  nr=`cat $count_file`
  let "nr += 1"
  echo "$nr" > $count_file
else
  touch $count_file
  echo "1" > $count_file
fi

nr=`cat $count_file`

if [ $nr -gt $nr_keep ]
then

#### LOG FILE
log_file="${log_dir}/$nome_file_bkp-$fecha-ver.$nr.log"

if [ -f $log_file ];
then

##### CANCELLAZIONE FILE in modalita' *FIFO*
if [ -f $log_dir/*-ver.$nr.* ];
then
  rm $log_dir/*-ver.$nr.*

##### INIZIO PROCEDURA DI BACKUP
echo "INIZIO BACKUP " $(date) >> $log_file

    else
      mkdir -p ${dest_dir_account}
      echo "${dest_dir_account} destination_dir CREATA, OK" >> $log_file
    fi

    ##### CANCELLAZIONE FILE in modalita' *FIFO*
    if [ -f ${dest_dir_account}/*-ver.$nr.* ];
    then
