Backup of whole Database

AnBad's profile image AnBad posted 2 months ago in General

Hello, good morning,

what is the simplest way to make an backup of an whole mariaDB-Database?

I was hoping HeidiSQL running in Win10Pro is providing an easy way to do this, cause I dont have any expirience with Managing a databases what so ever.

How to do a backup? And of course, how to restore it?

Is there anywhere a stepbystep tutorial? :-)

I Need this, because I have to upgrade my Raspbian operating System and my FHEM.

Kind regards!!

Of course, this is one of Heidi's most used features I suppose. Just rightclick a database, then click "Export database as SQL". In the following dialog you have a few options where you can play with. For a full backup I recommend activating

  • create database
  • create tables
  • data: insert
  • max insert size: 1024K
  • output: single .sql file

There is an online help for that dialog, and it is just a click away, if you click on the question mark in the title bar of that dialog. It will take you to that verbose help section.

Restoring such an .sql file is easy: just click File > "Run SQL file", and select your backup file (and this is important: chose the right encoding, eg "UTF-8"). The rest is just to sit and wait for the restore window to finish.

  1. Export via: Tools/database Export
