如何远程执行该.sh文件以获取数据库并将其拉回？

该文件是chmod 777所以它没有被隐藏

我试过这样的事情,但我没有得到任何复制/拉过来.

backup_script  /usr/bin/ssh root@example.com 'mysqldump -u root --all-databases | gzip --rsyncable > ~/all.sql.gz'    unused2

尝试：

backup_script /usr/bin/ssh user@website.com "/home/user/backup.script"  whatever/

它工作但无法复制文件.

编辑：

backup_script   /usr/bin/ssh root@remote.com "/home/user/backup_mysql.sh"   blank/
backup_script   /usr/bin/scp -r root@remote.com:/.rsnapshots/tmp/ /.rsnapshots/tmp/       user/mysql/

得到：
