我正在使用rsnapshot，我的configuration如下：
config_version 1.2 snapshot_root /home/user/.snapshots/ cmd_cp /bin/cp cmd_rm /bin/rm cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh cmd_logger /usr/bin/logger cmd_du /usr/bin/du cmd_rsnapshot_diff /usr/bin/rsnapshot-diff interval hourly 24 interval daily 7 interval weekly 4 verbose 2 loglevel 3 logfile /home/user/rsnapshot.log lockfile /home/user/rsnapshot.pid backup [email protected]:/home/user/ website/ backup_script [email protected]:/home/user/backup_mysql.sh website/mysql/ 我的sql备份文件:(故意留下来的东西）

如何远程执行.sh文件来抓取数据库并将其拉回来？
编辑：错误：

该文件是chmod 777所以它不隐藏
我尝试了这样的事情，但我没有得到任何东西复制/拉过来。
backup_script /usr/bin/ssh [email protected] 'mysqldump -u root --all-databases | gzip --rsyncable > ~/all.sql.gz' unused2
尝试：
backup_script /usr/bin/ssh [email protected] "/home/user/backup.script" whatever/
它的工作，但未能复制文件。
编辑：
backup_script /usr/bin/ssh [email protected] "/home/user/backup_mysql.sh" blank/ backup_script /usr/bin/scp -r [email protected]:/.rsnapshots/tmp/ /.rsnapshots/tmp/ user/mysql/
得到：

首先，您应该将备份脚本移到远程系统。 请记住，文件正在远程系统上执行，而不是本地的（运行rsnapshot的）。 然后一旦程序在远程系统上执行，您应该将文件移回本地系统。
像这样的东西应该工作：
backup_script /usr/bin/ssh [email protected] "/home/user/backup.script" whatever/ backup_script /usr/bin/scp -r [email protected]:/home/user/your_data/ /.your_snapshot_root/rsnapshots/tmp/ target_dir_to_store_backups/
