自动备份VPS数据到Dropbox

相关截图如下

执行脚本后的显示：

在Dropbox中成功备份：

以下便是脚本的相关内容：

vim DropboxBackup.sh 
chmod +x DropboxBackup.sh
crontab -e //设置为每个月执行一次备份，具体时间可以根据需要进行修改 
00 02 1 * * /bin/bash  /root/DropboxBackup.sh

vim DropboxBackup.sh

chmod +x DropboxBackup.sh

crontab -e //设置为每个月执行一次备份，具体时间可以根据需要进行修改

00 02 1 * * /bin/bash /root/DropboxBackup.sh
