Redmine

h1. Backing up and restoring Redmine

{{>toc}}

h2. Backup

Redmine backups should include:

* Database

* Attachments (stored in the @files@ directory of your Redmine install)

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 the @files/@ directory. You can copy the contents of this directory to another location to easily back it up.

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
