There is several reason why it is important to "backup" a complete instance of Dolibarr. For example:
- Because you plan to make an upgrade and want to do a go back to previous version if it fails.
- Because you want to move Dolibarr from one server to another server.
- And of course, to be able to make a restore to be safe if something bad happens (crash disk, hack corruption, ...)
For all this reasons, it is recommended to make backup of all data used and saved by Dolibarr.
What to save ?
Dolibarr save its data in 3 different spaces. They all must be saved before each version upgrade to be sure to be able to get back its data if a problem occurs or if you want to go back on previous version. This is the 3 kind of data you need to save to be sure to loose nothing.
The configuration file
The configuration file should not be modified by upgrade process, but it is more prudent to save it also when you do an upgrade. The configuration file is called conf.php and you can find it into directory dolibarrdir/htdocs/conf/. Make a copy of this file into the dedicated area of your backup. This backup is however optional as you can still rebuild this file if you know all your connexion id (this file contains only parameters to connect to database and directory where you Dolibarr is installed). When making a restore, it is still possible to rebuild this file by an installation from scratch.
The database
The database contains all data you have added from Dolibarr screens (except the attached files that are presented in next chapter). Saving the database must be done in a global way (all content). See the chapter "How" later in this document.
Documents
All documents related to your Dolibarr instance are saved into directory defined into your config file dolibarrdir/htdocs/conf/conf.php. If you kept the choice by default during first installation, it should be something like dolibarrdir/documents. This directory must be completely saved. When making an upgrade, the upgrade process should not change this directory, however this directory can be read and write by web server at any time, it might be altered by a bad action or a bug. To be sure to keep all your joined files and be able to restore them if they are accidentally deleted or altered, just make a copy of all content of this directory.
When
Frequency of backups depends on how often you use Dolibarr and what you accept to loose if something happens. More the frequency is important, less you will loose data if need to erase you software with a backup.
How
The configuration file
A simple copy of file conf/conf.php into a directory dedicated to your backup is enough.

页面等待翻译。若要翻译本页，先创建一个帐户、登录并返回本页后单击“编辑”。Si vous utilisez une version récente de Dolibarr, connectez vous avec le compte administrateur Dolibarr. Puis aller dans Accueil - Outils systemes puis Sauvegardes. Choisissez alors les options de sauvegardes (prendre tout par défaut si possible).
Si vous préferez le mode manuel, vous pouvez utiliser directement l'outil de sauvegarde de votre base.
Avec Mysql, la commande pour sauvegarder votre base de données dans un fichier est:
mysqldump -u utilisateur -pvotremotdepasse --result-file=dolibarr.date.sql base_de_données
où utilisateur est l'utilisateur MySQL que Dolibarr utilise pour se connecter à la base de données, votremotdepasse est le mot de passe du compte utilisateur MySQL (attention pas d'espaces entre le p et le mot de passe), date est une date que vous pouvez indiquer dans le nom du fichier de destination (ça vous aidera à vous y retrouver, plus tard, si vous avez plusieurs versions de sauvegardes), et base de données est le nom de la base de données que Dolibarr utilise.
Ces informations (utilisateur, mot de passe et base de données) sont disponibles dans votre fichier de configuration dolibarr/htdocs/conf/conf.php
The documents
Une copie du répertoire des documents (dolibarr/documents par défaut) dans un répertoire de sauvegarde dédié suffit. Si vous avez réalisez la sauvegarde de la base via l'outil système de Dolibarr, le fichier dump base de donnée se trouve également inclus dans cette copie.
