My WordPress backup script, which keeps daily, weekly and monthly backups of website files and database dumps.
Installation:
This should work on your garden variety Debian or Ubuntu server running WordPress and Mysql.
Copy this script to /usr/local/sbin/backup-websites
cat /etc/cron.d/backup-websites
# Backup websites and databases at around 3am
15 03 * * * root /usr/local/sbin/backup-websites
btw. sorry the indentation seems to go missing when I use the /code tag in WordPress.
The script…
backup-websites:
#!/bin/bash
# Backup websites and databases
####
# Set some variables and paths
BACKUP_DIR=home/backups/websites
# Must contain backup.monthly backup.weekly backup.daily folders
FILE_DIRS_BASE=var/www
DATABASES=`echo "show databases" | /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf | grep -v Database | grep -v schema`
email=root@localhost
######
# Make appropriate destination directory
# Destination file names
date_daily=`date +"%Y-%m-%d"`
# Get current month and week day number
month_day=`date +"%d"`
week_day=`date +"%u"`
# On first month day do monthly
if [ "$month_day" -eq 1 ] ; then
destination=backup.monthly/$date_daily
else
# On Saturdays do weekly
if [ "$week_day" -eq 6 ] ; then
destination=backup.weekly/$date_daily
else
# On any regular day do daily
destination=backup.daily/$date_daily
fi
fi
cd /$BACKUP_DIR
mkdir $destination
# latest backup symlink
ln -snf $destination /$BACKUP_DIR/latest
####
# Create backup files in today's directory
stamp=`date +%Y-%m-%d_%H-%M-%S`
# Dump MySQL tables in incoming dir
for db in $DATABASES; do
/usr/bin/mysqldump --defaults-file=/etc/mysql/debian.cnf $db | bzip2 > \
/$BACKUP_DIR/$destination/$db.$stamp.sql.bz2
done
FILE_DIRS=`ls /$FILE_DIRS_BASE`
# Compress files, one tar file per sub directory
for filedir in $FILE_DIRS; do
tar -C / -cjf /$BACKUP_DIR/$destination/$filedir.$stamp.tar.bz2 $FILE_DIRS_BASE/$filedir
done
#####
# Email backup info
ls -l /$BACKUP_DIR/$destination/ | mail -s "[`uname -n`] Websites Backup $date_daily" $email
#####
# Clean up old backups
# Daily - keep for 7 days
find /$BACKUP_DIR/backup.daily/ -maxdepth 1 -mtime +7 -type d -exec rm -rf {} \;
# Weekly - keep for 30 days
find /$BACKUP_DIR/backup.weekly/ -maxdepth 1 -mtime +30 -type d -exec rm -rf {} \;
# Monthly - keep for 365 days
find /$BACKUP_DIR/backup.monthly/ -maxdepth 1 -mtime +365 -type d -exec rm -rf {} \;
#END
Keep your backups for less time by updating mtime above.
To recover your backups:
tar jxvf your-backup-file.tar.bz2
bunzip2 your-backup-file.sql.bz2
LLAP.
