The following mainly brings you backup mysql through innobackup combined with planned tasks. I hope these contents can bring you practical use, which is also the main purpose of my editor to achieve backup mysql through innobackup combined with scheduled tasks. All right, don't talk too much nonsense, let's just read the following.

Write a script to make automatic full and incremental backups

Full backup

Refresh the binlog log

Vim / root/newbak.sh

#! / bin/bash

D1=date +% F / / defines the time, distinguished by date

D2=date +% F-d "- 1 days" / / find yesterday's date to indicate the backup file from the last backup

Dir1=/backup/allbak$ {d2} / / full backup files made yesterday

Dir2=/backup/newbak$ {D2} / / incremental backup files made yesterday

User=root

Pass=123456

[!-e / backup] & & mkdir / backup / / create a folder if the file does not exist

If [- e ${dir1}]; then / / judged that what was done yesterday was a full backup

Innobackupex-- user $user-- password $pass-- incremental / backup/newbak$ {D1}-- incremental-basedir=$ {dir1}-- no-timestamp / / specifies the full backup file that was backed up yesterday

Elif [- e ${dir2}]; then / / judged that what was done yesterday was an incremental backup

Innobackupex-- user $user-- password $pass-- incremental / backup/newbak$ {D1}-- incremental-basedir=$ {dir2}-- no-timestamp / / specify the incremental backup files backed up yesterday

Else

Innobackupex-user $user-password $pass / backup/allbak$ {D1}-no-timestamp

/ / if there was neither incremental backup nor full backup yesterday, do a full backup.

Fi

Add permission: chmod + x / root/allbak.sh chmod + x / root/newbak.sh write schedule task: crontab-e 00 03 * * 1 / root/allbak.sh & > / dev/null / / perform a full backup 00 04 * * 2-7 / root/newbak.sh & > / dev/null / / perform an incremental backup to restart the crond service systemctl restart crond at 4: 00 a.m. from Tuesday to Sunday

Systemctl enable crond

For the above about the combination of innobackup with scheduled tasks to achieve backup mysql, we do not think it is very helpful. If you need to know more, please continue to follow our industry information. I'm sure you'll like it.
