PHP备份脚本仅用于备份public_html

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.PHP脚本也可以从/ public_html / backups /文件夹运行。有关如何限制从'/'保存到'/ public_html /'的任何想法吗？谢谢！

你只需要改变tar命令的第三个输入

$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);
