Linux Automatic scheduled backup folder and Backup script instance

Server:Aliyun

Requirements:For the WWW directory, perform a backup daily 1 o'clock in the morning to name the folder on today's date


Create Wwwbak directories and bakwww.sh files in the Alidata folder as follows:

Create a new Wwwbak folder and execute the following command:
# mkdir Wwwbak
# Chmod-r 777 Wwwbak

To create a new bakwww.sh file, execute the following command
# VI bakwww.sh

The contents of the document are as follows:
cp-af/alidata/www//alidata/wwwbak/$ (date-d "Today" + "%y%m%d_%h%m%s")/

Meaning of this line: copy/alidata/www/to the/alidata/wwwbak/directory and name the folder with the current date


Press ESC to enter: Wq save

Let bakwww.sh have execute permission to execute the following command:
# Chmod-r 777 Bakwww.sh


－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－


Switch to the ETC directory and execute the following command:
# VI Crontab

On the last line, enter:
0 1 * * * root/alidata/bakwww.sh

Meaning of this line: bakwww.sh files are executed 1 o'clock in the morning every day


Finally restart the Crontab service
# Service Crond Restart

This is the end of it.


The above should note is: bakwww.sh file must have the permission to execute!



LINUX Automatic backup script files

First I set up a folder under the/root/backup directory,

#mkdir/root/backup/mysqlbackup

Later at five o'clock every day, there will be a file saved here.

Then create a new file

#vim/root/mysqlautobak

Input:

Filename= ' Date +%y%m%d '

mysqldump--all-databases-uroot-p (mysql password) >/root/backup/mysqlbackup/mysql$file.sql

　　

Save Exit!

So that it can perform

#chomd +x/root/mysqlautobak

And then the crontab started.

#vi/etc/crontab

　　

Add a row

　　

5 * * * Root/root/mysqlautobak

Save exit.

Restart your Crond service process

#/etc/rc.d/init.d/crond Restart

Don't forget, the last step is to add a task to the crontab so you don't have to tap into trivial commands every time you backup.


Linux under:

MySQL:: Linux to automatically back up the database shell script
The program on the Linux server updates the MySQL database every day, and then remembers to write a shell script that combines crontab to back up the database regularly. Actually very simple, the main is to use the mysqldump command with MySQL.

The script reads as follows:
#!/bin/sh
# File:/home/mysql/backup.sh
# Database Info
Db_name= "Test"
Db_user= "username"
db_pass= "Password"

# others VARs
Bin_dir= "/usr/local/mysql/bin"
Bck_dir= "/home/mysql/backup"
Date= ' Date +%f '

# TODO
$BIN _dir/mysqldump--opt-u$db_user-p$db_pass $DB _name | gzip > $BCK _dir/db_$date.gz


Then use this script to add to the/etc/crontab timed task:

5 * * 0 mysql/home/mysql/backup.sh

OK, every Sunday 5:01 the system will automatically run backup.sh file backup MySQL database.
