h1. Backing up and restoring Redmine 

 {{>toc}} 

 h2. Backup 

 Redmine backups should include: 
 * Database 
 * Attachments (stored in the @files@ directory under the installation directory by default) 

 h3. Backing up database 

 h4. MySQL 

 The @mysqldump@ command can be used to backup the contents of your MySQL database to a text file. For example: 
 <pre> 
 /usr/bin/mysqldump -u <username> -p<password> -h <hostname> <redmine_database> > /path/to/backup/db/redmine.sql 
 </pre> 

 You can find @<username>@, @<password>@, @<hostname>@, and @<redmine_database>@ in the file @config/database.yml@. @<host_name>@ may not be required depending on your installation of the database. 

 h4. PostgreSQL 

 The @pg_dump@ command can be used to backup the contents of a PostgreSQL database to a text file. Here is an example: 
 <pre> 
 /usr/bin/pg_dump -U <username> -h <hostname> -Fc --file=redmine.sqlc <redmine_database> 
 </pre> 

 You can find @<username>@, @<hostname>@, and @<redmine_database>@ in the file @config/database.yml@. @<hostname>@ may not be required depending on your installation of the database. The @pg_dump@ command will prompt you to enter the password when necessary. 

 h4. SQLite 

 SQLite databases are all contained in a single file, so you can back them up by copying the file to another location. 

 You can determine the file name of SQLite database by looking at @config/database.yml@. 

 h3. Backing up attachments 

 All file uploads are stored in @attachments_storage_path@ (defaults to the @files/@ directory). You can copy the contents of this directory to another location to easily back it up. 

 WARNING: @attachments_storage_path@ may point to a different directory other than @files/@. Be sure to check the setting in @config/configuration.yml@ to avoid making a useless backup. 

 h3. Sample backup script 

 Here is a simple shell script that can be used for daily backups (assuming you're using a MySQL database): 

 <pre> 
 # Database 
 /usr/bin/mysqldump -u <username> -p<password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%Y-%m-%d`.gz 

 # Attachments 
 rsync -a /path/to/redmine/files /path/to/backup/files 
 </pre> 

 h2. Restore 

 h3. Restoring a database 

 h4. MySQL 

 For example if you have a gziped dump file with the name @2018-07-30.gz@, 2018-07-30.gz, then the database can be restored with the following command: 

 <pre> 
 gunzip -c 2018-07-30.gz | mysql -u <username> --password <redmine_database> 
 Enter password: 
 </pre>
