I believe that many webmasters or independent Blog bloggers have the need to back up databases. Of course, there are many plug-ins that can help you complete this task in a rich Blog system such as WordPress. If you need to back up the database by yourself, I will post a Mysql automatic backup script for your reference. What you can see on a foreign website is still good, so you can regularly back up the Mysql database, in addition, you can choose to make a full backup of files under the specified directory on the day of each week. The backup files are automatically uploaded to the specified FTP to ensure the reliability of backup. If you just back up the database together with the database, it doesn't mean much.
Copy codeThe Code is as follows :#! /Bin/sh
# System + MySQL backup script
# Full backup day-Sun (rest of the day do incremental backup)

### System Setup ###
# Back up the local directory of the local file ##

# Date formats can be adjusted by yourself ##
NOW = $ (date + "% Y-% m-% d ")
INCFILE = "/home/xxxx"
DAY = $ (date + "% u ")
# Daily full backup can be adjusted by yourself ##
FULLBACKUP = "7"
### MySQL Setup ###
MUSER = "chaos"
MPASS = "password"
MHOST = "host"
MYSQL = "$ (which mysql )"
MYSQLDUMP = "$ (which mysqldump )"
GZIP = "$ (which gzip )"
### FTP server Setup ###

### Other stuff ###

### Start MySQL Backup ###
# Get all databases name

Done
### Dump backup using FTP ###
# Start FTP backup using lftp
# Ncftp can be automatically adjusted on ubuntu ##
# Ncftp-u "$ FTPU"-p "$ FTPP" $ FTPS <EOF
Lftp-u $ FTPU, $ FTPP $ FTPS <EOF
Mkdir $ FTPD

### Find out if ftp backup failed or not ###
If ["$? "=" 0 "]; then
Rm-f $ BACKUP /*
