要备份的数据类型

• 数据库中的数据
• 用户上传的附件

Redmine backups should include:

• Database
• Attachments (stored in the files directory under the installation directory by default)

备份数据库数据

• MySQL

  The mysqldump command can be used to backup the contents of your MySQL database to a text file. For example:

  /usr/bin/mysqldump -u <username> -p<password> -h <hostname> <redmine_database> > /path/to/backup/db/redmine.sql
  

  You can find ,, , and in the file config/database.yml. `` may not be required depending on your installation of the database.

• PostgreSQL

  The pg_dump command can be used to backup the contents of a PostgreSQL database to a text file. Here is an example:

  /usr/bin/pg_dump -U <username> -h <hostname> -Fc --file=redmine.sqlc <redmine_database>
  

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

• 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.

备份用户上传的附件

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.

备份脚本

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

# 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

恢复数据库

• MySQL

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

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

• PostgreSQL

  When the option -Fc of the command pg_dump is used like it is at the above example then you need to use the command pg_restore:

  pg_restore -U <username> -h <hostname> -d <redmine_database> redmine.sqlc
  

  otherwise a text file can be restored with psql:

  psql <redmine_database> < <infile>
  

• SQLite

  Copy the database file from the backup location.
