# Dump A Database To A File
|
|
|
|
The `mysqldump` client is a handy tool for creating a backup or snapshot of
|
|
a MySQL database. The standard use of this command produces an alphabetical
|
|
series of statements that comprise the structure and data of the specified
|
|
database. It directs all of this to `stdout`. You'll likely want to redirect
|
|
it to a file.
|
|
|
|
```bash
|
|
$ mysqldump my_database > my_database_backup.sql
|
|
```
|
|
|
|
The output will include special comments with MySQL directives that disable
|
|
things like constraint checking. This is what allows the output to be in
|
|
alphabetical order without necessarily violating any foreign key
|
|
constraints.
|
|
|
|
If you need to dump multiple databases, include the `--databases` flag with
|
|
a space-separated list of database names. Or dump all of them with
|
|
`--all-databases`.
|
|
|
|
See `man mysqldump` for more details.
