h2. Backup
6 1 Go MAEDA
7 1 Go MAEDA
Redmine backups should include:
8 1 Go MAEDA
* Database
9 4 Go MAEDA
* Attachments (stored in the @files@ directory under the installation directory by default)
10 1 Go MAEDA
11 1 Go MAEDA
h3. Backing up database
12 1 Go MAEDA
13 1 Go MAEDA
h4. MySQL
14 1 Go MAEDA
15 1 Go MAEDA
The @mysqldump@ command can be used to backup the contents of your MySQL database to a text file. For example:
16 1 Go MAEDA
<pre>
17 4 Go MAEDA
/usr/bin/mysqldump -u <username> -p<password> -h <hostname> <redmine_database> > /path/to/backup/db/redmine.sql
18 1 Go MAEDA
</pre>
19 1 Go MAEDA
20 2 Go MAEDA
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.
21 2 Go MAEDA
22 1 Go MAEDA
h4. PostgreSQL
23 1 Go MAEDA
24 1 Go MAEDA
The @pg_dump@ command can be used to backup the contents of a PostgreSQL database to a text file. Here is an example:
25 1 Go MAEDA
<pre>
26 2 Go MAEDA
/usr/bin/pg_dump -U <username> -h <hostname> -Fc --file=redmine.sqlc <redmine_database>
27 1 Go MAEDA
</pre>
28 1 Go MAEDA
29 2 Go MAEDA
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.
30 2 Go MAEDA
31 1 Go MAEDA
h4. SQLite
32 1 Go MAEDA
33 1 Go MAEDA
SQLite databases are all contained in a single file, so you can back them up by copying the file to another location.
34 2 Go MAEDA
35 2 Go MAEDA
You can determine the file name of SQLite database by looking at @config/database.yml@.
36 1 Go MAEDA
37 1 Go MAEDA
h3. Backing up attachments
38 1 Go MAEDA
39 3 Go MAEDA
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.
40 3 Go MAEDA
41 3 Go MAEDA
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
44 1 Go MAEDA
45 1 Go MAEDA
Here is a simple shell script that can be used for daily backups (assuming you're using a MySQL database):
46 1 Go MAEDA
47 1 Go MAEDA
<pre>
48 1 Go MAEDA
# Database
49 1 Go MAEDA
/usr/bin/mysqldump -u <username> -p<password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%Y-%m-%d`.gz
50 1 Go MAEDA
51 1 Go MAEDA
# Attachments
52 1 Go MAEDA
rsync -a /path/to/redmine/files /path/to/backup/files
53 1 Go MAEDA
</pre>
54 1 Go MAEDA
55 1 Go MAEDA
h2. Restore

h4. 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:
62 5 Gerd Pokorra
63 5 Gerd Pokorra
<pre>
64 5 Gerd Pokorra
gunzip -c 2018-07-30.gz | mysql -u <username> --password <redmine_database>
65 5 Gerd Pokorra
Enter password:
66 5 Gerd Pokorra
</pre>
67 5 Gerd Pokorra
68 5 Gerd Pokorra
h4. PostgreSQL
69 5 Gerd Pokorra
70 7 Gerd Pokorra
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@:
71 7 Gerd Pokorra
72 7 Gerd Pokorra
<pre>
73 7 Gerd Pokorra
pg_restore -U <username> -h <hostname> -d <redmine_database> redmine.sqlc
74 7 Gerd Pokorra
</pre>
75 7 Gerd Pokorra
76 7 Gerd Pokorra
otherwise a text file can be restored with @psql@:
77 7 Gerd Pokorra
78 7 Gerd Pokorra
<pre>
79 7 Gerd Pokorra
psql <redmine_database> < <infile>
80 7 Gerd Pokorra
</pre>
