1. Backup under /var/www/html
①Create backup script file
# cd /var/www/system
# vi backup_html.sh
Contents of backup_html.sh
#!/bin/bash
TODAY=`/bin/date +%Y%m%d`
DAY_AGO=`/bin/date --date '10day ago' +%Y%m%d`
HTML_DIR="/var/www/html"
BACKUP_DIR="/var/www/backup/html_bak"
RUN_FLAG="/var/www/backup/html_bak/html_flag"
/bin/mkdir -p ${BACKUP_DIR}
/bin/touch ${RUN_FLAG}
/bin/tar vfcz ${BACKUP_DIR}/html_back_${TODAY}.tar.gz ${HTML_DIR}
/bin/chmod 644 ${BACKUP_DIR}/html_back_${TODAY}.tar.gz
if [ -f ${BACKUP_DIR}/html_back_${DAY_AGO}.tar.gz ];
then
/bin/rm -f ${BACKUP_DIR}/html_back_${DAY_AGO}.tar.gz
fi
/bin/rm -f ${RUN_FLAG}
➁Set permissions
# chmod 700 backup_html.sh
➂Create save directory and Set permissions
# mkdir -p /var/www/backup/html_bak
# chmod 777 /var/www/backup/html_bak
④scheduled execution
Add settings to cron to run backups daily at 6:00 a.m.
# crontab -e
0 6 * * * /var/www/system/backup_html.sh > /dev/null 2>&1
2. MariaDB database backup
①Create backup script file
# cd /var/www/system
# vi db_backup.sh
Contents of db_backup.sh
#!/bin/bash
export LANG=ja_JP.eucJP
export PATH="$PATH":/usr/bin
export MYSQL_HOME=/usr/local/mysql
export MYLIB=${MYSQL_HOME}/lib
export MANPATH="${MANPATH}":${MYSQL_HOME}/man
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}":"${MYLIB}"
MYUSER="root" #MariaDB connection username
MYPASS="xxxxxxxxxxx" #MariaDB connection password
TIME_STRING=`/bin/date '+%Y%m%d'`
DAY_AGO=`/bin/date --date '10day ago' +%Y%m%d`
DB_BAK_DIR="/var/www/backup/db_bak"
RUN_FLAG="${DB_BAK_DIR}/db_my_flag"
MYSQL_BACKUP_FILE=${DB_BAK_DIR}/mariadb_backup_"${TIME_STRING}".dump
/bin/mkdir -p ${DB_BAK_DIR}
/bin/touch ${RUN_FLAG}
mysqldump -u${MYUSER} -p${MYPASS} --all-databases > ${MYSQL_BACKUP_FILE}
/bin/gzip ${MYSQL_BACKUP_FILE}
if [ -f ${DB_BAK_DIR}/${MT_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${MT_DB}"${DAY_AGO}".dump.gz
fi
if [ -f ${DB_BAK_DIR}/${XOOPS_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${XOOPS_DB}"${DAY_AGO}".dump.gz
fi
if [ -f ${DB_BAK_DIR}/${GEEKLOG_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${GEEKLOG_DB}"${DAY_AGO}".dump.gz
fi
/bin/rm -f ${RUN_FLAG}
➁Set permissions
# chmod 700 db_backup.sh /var/www/system/db_backup.sh
➂Create save directory and Set permissions
# mkdir -p /var/www/backup/db_bak
# chmod 777 /var/www/backup/db_bak
④scheduled execution
Add settings to cron for periodic backups
# crontab -e
0 7 * * * /var/www/system/db_backup.sh > /dev/null 2>&1

# tar zxvf html_back_[time stamp].tar.gz
4. Restore MariaDB backup file
