Periodic backup of database

Periodic backup of database can be taken by using scripts like:

#!/bin/sh
BACKUP_DIR=<backup_dir>/$(date +%Y-%m-%d)
mkdir -p $BACKUP_DIR
mysqldump -u <user-name> -p<password> <database-name> > $BACKUP_DIR/`date +%Y-%m-%d\:%H-%M-%S`.sql

exit 0

Replace: <backup_dir>, <user-name>, <password> and <database-name> appropriately.

This script can be put in '/etc/cron.hourly' or '/etc/cron.daily' or '/etc/cron.weekly' or '/etc/cron.monthly' based on frequency of backups desired.

  • Make sure to do 'chmod +x' on script so that it is executable.
  • If you do not want to be bothered by cron output of above script then add '>/dev/null 2>&1' at end of all commands
