backup.scm OPTIONS
Creates a MySQL dump file and a tarball from source directory, compresses
both files with XZ, places them into the backup directory and prints the
file names on standard output.
MySQL backup relies on socket authentication.
Options:
-i, --source-dir=DIR Create tarball from DIR
-o, --backup-dir=DIR Write backup files to DIR
-X, --exclude-from=FILE Exclude files using patterns from FILE.
See tar manual of the same option.
-u, --mysql-user=USER Use USER for MySQL authentication (default: root)
-S, --mysql-socket=SOCKET Use SOCKET for MySQL connection and authentication
(default: /run/mysqld/mysqld.sock)
-p, --file-prefix=PREFIX File name prefix (default: \"\")
-h, --help Display this help
MySQL backup relies on socket authentication, for which a MySQL user
and corresponding UNIX user is needed. Socket authentication plugin is
called unix_socket in MariaDB and
auth_socket in MySQL.
You should grant only the privileges necessary to do the backup. From mysqldump docs:
mysqldump requires at least the SELECT privilege for dumped tables,
SHOW VIEW for dumped views, TRIGGER for dumped triggers, LOCK TABLES
if the --single-transaction option is not used, and (as of MySQL 8.0.21)
PROCESS if the --no-tablespaces option is not used. Certain options
might require other privileges as noted in the option descriptions.
Grant the privileges on the databases you want to appear in the dump file.
CREATE USER 'backup'@'localhost' IDENTIFIED WITH unix_socket;
GRANT SELECT,SHOW VIEW,TRIGGER,LOCK TABLES ON foo.* TO 'backup'@'localhost';
FLUSH PRIVILEGES;
In your operating system config, you could add this script as a local-file,
which is then executed via mcron. Note #:recursive #t which preserves
the permission bits on backup.scm.
(define backup-script
(local-file "backup.scm/backup.scm"
#:recursive? #t))
(define backup-job
#~(job '(next-hour '(0))
(lambda ()
(execl #$backup-script #$backup-script))))
(operating-system
(services
(append (list (simple-service 'backup-jobs
mcron-service-type
(list backup-job)))
%base-services)))
