尝试使用 mariabackup 备份我们所有的数据库。首先创建的备份目录为
mkdir -p /mnt/data/backup/mariadb
chown -R mysql:mysql /mnt/data/backup/mariadb
并继续做备份
# mariabackup --backup --target-dir=/mnt/data/backups/mariadb/ --user=root --password=xxxxxxxx

尝试了护目镜和各种选项它没有工作所以最后尝试没有 --target-directory 选项并再次进行备份，它成功运行并得到了这个
# ls -ld /mnt/data/backup
drwxr-xr-x 3 mysql mysql 21 Feb 6 11:41 /mnt/data/backup
# pwd
/mnt/data/mysql
# ll
total 8
drwxr-xr-x 3 mysql mysql 21 Feb 6 11:41 backup
drwxr-xr-x 27 mysql mysql 4096 Feb 4 19:07 mysql

我做错了什么或如何使用 ----target-directory 运行它
