10.4(EOL), 10.5
Description
Mariabackup's --help option seemed to disappear in MariaDB 10.5.4.
For example, we can see here that the option existed in MariaDB 10.4.13:
$ mariadb-backup --version
|
mariadb-backup based on MariaDB server 10.4.13-MariaDB debian-linux-gnu (x86_64)
|
$ mariadb-backup --help
|
mariadb-backup based on MariaDB server 10.4.13-MariaDB debian-linux-gnu (x86_64)
|
Open source backup tool for InnoDB and XtraDB
|
...
|
Usage: mariadb-backup [--defaults-file=#] [--backup | --prepare | --copy-back | --move-back] [OPTIONS]
|
|
|
Default options are read from the following files in the given order:
|
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
|
The following groups are read: xtrabackup mariabackup mysqld server mysqld-10.4 mariadb mariadb-10.4 client-server galera
|
The following options may be given as the first argument:
|
--print-defaults Print the program argument list and exit.
|
--no-defaults Don't read default options from any option file.
|
The following specify which files/extra groups are read (specified before remaining options):
|
--defaults-file=# Only read default options from the given file #.
|
--defaults-extra-file=# Read this file after the global files are read.
|
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
|
-V, --verbose display verbose output
|
-v, --version print xtrabackup version information
|
...
|
But now in MariaDB 10.5.4, the option is no longer supported:
$ mariadb-backup --version
|
mariadb-backup based on MariaDB server 10.5.4-MariaDB debian-linux-gnu (x86_64)
|
$ mariadb-backup --help
|
mariadb-backup: unknown option '--help'
|
Could this be caused by the fix for MDEV-18215?
