BackupPC success mail triggering

Step 1

Go to Edit Config->Backup Setting and add the following lines into the DumpPostUserCmd

/opt/BackupPC/email_sample.sh $xferOK $host $type $client $hostIP $share $XferMethod $sshPath $cmdType

Before that we have to create email_sample.sh in that particular locations.

step 2

add the following scipt in email_sample.sh file and create  a txt file in /tmpas emailmessage.txt

#!/bin/bash
# script to send simple email
# Email To ?
EMAIL="your mail address"
# Email text/message
EMAILMESSAGE="/tmp/emailmessage.txt"

# Grab the status variables
xferOK=$1
host=$2
type=$3
client=$4
#hostIP=$5
share=$6
XferMethod=$7
#TopDir=$8
#cmdType=$9

#Extract the info file
#LOG_FILE="/u01/BackupPC/pc/$host//backupInfo"
 
LOG_FILE=`ls -t /u01/BackupPC/pc/$host/*/backupInfo | /usr/bin/head -1`
 
# Check if backup succeeded or not.
if [[ $xferOK == 1 ]]; then
        STATUS="SUCCESS"
else
        STATUS="FAILED"
fi

# email subject
SUBJECT="[BackupPC] $STATUS for host: $client"

# Email text/message
echo "Filesystem backup for $host $STATUS" > $EMAILMESSAGE
echo "" >>$EMAILMESSAGE
echo "Type: $type" >>$EMAILMESSAGE
#echo "Client: $client" >>$EMAILMESSAGE
echo "Host: $host" >>$EMAILMESSAGE
#echo "Host IP: $hostIP" >>$EMAILMESSAGE
echo "Share: $share" >>$EMAILMESSAGE
echo "XferMethod: $XferMethod" >>$EMAILMESSAGE
#echo "BackupPath: $TopDir" >>$EMAILMESSAGE
#echo "cmdType: $cmdType" >>$EMAILMESSAGE
echo "BackupDetails: $LOG_FILE" >>$EMAILMESSAGE
cat $LOG_FILE >>$EMAILMESSAGE
# send an email using /bin/mail
/bin/mail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE
 
I have # some details if you required that you can enable it. 

Then change the owner to backuppcuser and provide execute permission

chown backuppc:backuppc email_sample.sh

chmod +x email_sample.sh

Now you will receive success and failure message whenever the backup start. 

BackupPC installation and configuration in rhel 6 and rhel 7

Step 1

Install latest epelreository  

For RHEL 6

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

For RHEL 7

rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

Install the required dependencies that mentioned below.

yum -y install perl-Compress-Zlib perl-Archive-Zip perl-File-RsyncP perl-suidperl openssh-clients expect perl-XML-RSS httpd

Step 2

For RHEL 6

Create a user for backuppc

useradd backuppc
passwd backuppc

Now install backuppc with below command

yum install BackupPC -y

Now set the password for BackupPC web portal 

htpasswd -c /etc/BackupPC/apache.users backuppc

it will promt for password.

make some changes in /etc/httpd/conf.d/BackupPC.conf

It looks like below

AuthType Basic
AuthUserFile /etc/BackupPC/apache.users
AuthName "backuppc"

<IfModule mod_authz_core.c>
  # Apache 2.4
  <RequireAll>
    Require valid-user
    <RequireAny>
      Require local
    </RequireAny>
  </RequireAll>
</IfModule>
<IfModule !mod_authz_core.c>
  # Apache 2.2
  order deny,allow
  deny from all
  #allow from 127.0.0.1
  #allow from ::1
  allow from all
#  require valid-user
</IfModule>

Now make a copy the config file for backup

cp /etc/BackupPC/config.pl /etc/BackupPC/config.pl_bkp

now edit the config file

vi /etc/BackupPC/config.pl

Make a changes in the following lines

$Conf{ServerInitdPath} = '/etc/init.d/backuppc';
$Conf{ServerInitdStartCmd} = '$sshPath -p 222 -i /u01/BackupPC/ssh-BKPPC-key -q -x -l root $serverHost$serverInitdPath start';
$Conf{CgiAdminUsers} = 'backuppc'; 

also cross check the following

$Conf{ServerHost} = 'localhost';
$Conf{BackupPCUser} = 'backuppc';
$Conf{TopDir} = '/var/lib/BackupPC/';
$Conf{ConfDir} = '/etc/BackupPC/';
$Conf{LogDir} = '/var/log/BackupPC';
$Conf{InstallDir} = '/usr/share/BackupPC';
$Conf{CgiDir} = '/usr/share/BackupPC/sbin/';

For RHEL 7

yum install backuppc nfs-utils bzip2 -y

start the backuppc servives with below command

systemctl start backuppc.service

set the permission as below

cd /usr/share/BackupPC

chown backuppc:backuppc sbin/*

cd sbin/

chmod u+s BackupPC_Admin

usermod -s /bin/bash backuppc

Now edit the config file and made a changes like below

vi /etc/BackupPC/config.pl

$Conf{CgiAdminUsers} = ”;
to

$Conf{CgiAdminUsers} = ‘backuppc’;

and change another content like below

$Conf{PingPath} = ";

to

$Conf{PingPath} = ‘/bin/ping’; 

Now edit the apache configuration like below

vi /etc/httpd/conf.d/BackupPC.conf

<IfModule mod_authz_core.c>
  # Apache 2.4
  <RequireAll>
    Require valid-user
    <RequireAny>
      Require valid-user
    </RequireAny>
  </RequireAll>
</IfModule>
<IfModule !mod_authz_core.c>
  # Apache 2.2
  AllowOverride All
  order deny,allow
  deny from all
  #allow from 127.0.0.1
  #allow from ::1
  #require valid-user
  allow from all
</IfModule>

Create username and password for backuppc GUI with below command

htpasswd -c /etc/BackupPC/apache.users backuppc

Step 3



Grant passwordless sudo access for backuppc user

visudo

add the below line in last

Defaults !lecture
backuppc ALL=NOPASSWD:/bin/gtar,/bin/tar

and # the following line

Defaults requiretty

to 

#Defaults requiretty

Now start the httpd and backuppc

service httpd start

service backuppc start

now makes it enable

chkconfig httpd on

chkconfig backuppc on


Now access the backuppc in url

http://ipaddress/backuppc



Follow the link for ssh passwordless authentication with key file

http://raindocs.blogspot.com/2018/08/ssh-passwordless-authentication-with.html

and change the RsyncClientCmd and RsyncClientRestoreCmd like below

RsyncClientCmd:

$sshPath -p 222 -i /path/of/ssh-BKPPC-key -q -x -l root $host $rsyncPath $argList+

RsyncClientRestoreCmd:

$sshPath -p 222 -i /path/of/ssh-BKPPC-key -q -x -l root $host $rsyncPath $argList+ 

 Now add the client to the backuppc server and start taking backup.
