@VINAYDURGAM  This is from Enterprise Linux, might work the same with Debian but I am not 100% sure as have not tried that. We copy the data to a cifs share, here is the information sort of anonymized. I hope that helps out some.

Server Setup

# THis step is only for postgresql, so that the pg_dump command works in the scripts

vi ~/.pgpass

localhost:5432:dbname:postgres:password

chmod 600 ~/.pgpass

#required to connect to cifs server shares

yum install cifs-utils

#Create credential file for the network connection

vi ~/.smb-credentials (adding 3 lines):

 username=<user-name>

    password=<password>

    domain=<domain-name>

# hide this credentials file from other users:

    chmod 600 ~/.smb-credentials

# create mount point location

    mkdir /mnt/backupSAN

# add to fstab vi /etc/fstab add one line at the end looking like this

    //servername/team1-backup /mnt/backupSAN cifs credentials=/root/.smb-credentials,rw,vers=3.0,cache=strict,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1 0 0

# mount (since the final mount point is not mentioned – mapping takes place using value from /etc/fstab)

mount -t cifs -o credentials=/root/.smb-credentials //servername/team1-backup

Script 

#/bin/bash

now=$(date +"%m_%d_%Y")

cd /data

# delete yesterdays backup file (anything more than 10 hours old)

find /data -name "*.dmp" -type f -mmin +$((60*10)) -exec rm -f {} \;

# create backup file

pg_dump -h localhost -U postgres  -F c -b -v -f filename-$now.dmp dbname

chmod a+r *

# creating backup directory on san

mkdir -p /mnt/backupSAN/dbname/$now

# Copy backup file to san

rsync -av *.dmp /mnt/backupSAN/dbname/$now

exit
