只备份public_html的PHP备份脚本

Question

$filename= "Backup.tar"; // The name (and optionally path) of the dump file 
$ftp_server = "IP";  // Name or IP. Shouldn't have any trailing slashes and shouldn't be prefixed with ftp:// 
$ftp_port = "21"; // FTP port - blank defaults to port 21 
$ftp_username = "User";  // FTP account username 
$ftp_password = "Pass";  // FTP account password - blank for anonymous 
$filename = "public_html/backups/" . $filename . ".gz"; 

$command = "tar cvf ~/$filename ~/*"; 
$result = exec($command); 

$command = "gzip -9 -S .gz ~/$filename"; 
$result = exec($command); 

这是我使用的工作备份。它备份服务器上的所有内容，包括电子邮件（例如/ mail /），我只想备份/ public_html文件夹及其下的所有子目录，它在/ public_html/backups /文件夹中创建一个tar.gz文件。也从/ public_html/backups /文件夹运行任何想法如何限制从'/'保存到'/ public_html /'？谢谢！

你只需要改变第三个输入的tar命令

$filename= "Backup.tar"; // The name (and optionally path) of the dump file 
$ftp_server = "IP";  // Name or IP. Shouldn't have any trailing slashes and shouldn't be prefixed with ftp:// 
$ftp_port = "21"; // FTP port - blank defaults to port 21 
$ftp_username = "User";  // FTP account username 
$ftp_password = "Pass";  // FTP account password - blank for anonymous 
$filename = "public_html/backups/" . $filename . ".gz"; 

$command = "tar cvf ~/$filename /public_html/*"; 
$result = exec($command); 

$command = "gzip -9 -S .gz ~/$filename"; 
$result = exec($command);
