LinuxQuestions.org - backup log files

An Example script to backup Apache Server. The same way you can include access.log and error.log too:

Code:

#!/bin/bash

# A Simple Shell Script to Backup Red Hat / CentOS / Fedora / Debian / Ubuntu Apache Webserver and SQL Database

# Path to backup directories

DIRS="/home/vivek/ /var/www/html/ /etc"

 

# Store todays date

NOW=$(date +"%F")

 

# Store backup path

BACKUP="/backup/$NOW"

 

# Backup file name hostname.time.tar.gz

BFILE="$(hostname).$(date +'%T').tar.gz"

PFILE="$(hostname).$(date +'%T').pg.sql.gz"

MFILE="$(hostname).$(date +'%T').mysql.sq.gz"

 

# Set Pgsql username

PGSQLUSER="vivek"

 

# Set MySQL username and password

MYSQLUSER="vivek"

MYSQLPASSWORD="myPassword"

 

# Remote SSH server setup

SSHSERVER="backup.example.com" # your remote ssh server

SSHUSER="vivek"                # username

SSHDUMPDIR="/backup/remote"    # remote ssh server directory to store dumps

 

# Paths for binary files

TAR="/bin/tar"

PGDUMP="/usr/bin/pg_dump"

MYSQLDUMP="/usr/bin/mysqldump"

GZIP="/bin/gzip"

SCP="/usr/bin/scp"

SSH="/usr/bin/ssh"

LOGGER="/usr/bin/logger"

 

# make sure backup directory exists

[ ! -d $BACKUP ] && mkdir -p ${BACKUP} 

 

# Log backup start time in /var/log/messages

$LOGGER "$0: *** Backup started @ $(date) ***"

 

# Backup websever dirs

$TAR -zcvf ${BACKUP}/${BFILE} "${DIRS}"

 

# Backup PgSQL

$PGDUMP -x -D -U${PGSQLUSER} | $GZIP -c > ${BACKUP}/${PFILE}

 

# Backup MySQL

$MYSQLDUMP  -u ${MYSQLUSER} -h localhost -p${MYSQLPASSWORD} --all-databases | $GZIP -9 > ${BACKUP}/${MFILE}

 

# Dump all local files to failsafe remote UNIX ssh server / home server

$SSH ${SSHUSER}@${SSHSERVER} mkdir -p ${SSHDUMPDIR}/${NOW}

$SCP -r ${BACKUP}/* ${SSHUSER}@${SSHSERVER}:${SSHDUMPDIR}/${NOW}

 

# Log backup end time in /var/log/messages

$LOGGER "$0: *** Backup Ended @ $(date) ***"
