Hello

There is a problem with "Human readable archive". TAR accept only filename with 100 characters.

Then i'm modified code to create a ZIP file.
This function can be used for classic backup (not tested)

In the file "op.CreateFolderArchive.php"
Add this function
PHP Code:
<?php 

function createFolderZIP($folder, $zip)

{

    global $settings,$human_readable;



    $documents=$folder->getDocuments();

    foreach ($documents as $document){

        

        if (file_exists($settings->_contentDir.$document->getDir())){



            if ($human_readable){

            

                // create an archive containing the files with original names and DMS path 

                // thanks to Doudoux 



                $latestContent = $document->getLatestContent();

                if (is_object($latestContent))

                {

                    $zip->addFile(

                      $settings->_contentDir.$latestContent->getDir().$latestContent->getVersion().$latestContent->getFileType(),

                      getFolderPathPlainAST($folder)."/".$document->getID()."_".mydmsDecodeString($latestContent->getOriginalFileName()));

                }

            

            }else{



                // create a server backup archive



                $handle = opendir($settings->_contentDir.$document->getDir());

                while ($entry = readdir($handle) )

                {

                    if (!is_dir($settings->_contentDir.$document->getDir().$entry)){



                      $zip->addFile($settings->_contentDir.$document->getDir().$entry,$document->getDir().$entry);

                    }



                }

                closedir($handle);

            }

        }    

    }



    $subFolders=$folder->getSubfolders();

    foreach ($subFolders as $folder)

        if (!createFolderZIP($folder, $zip))

            return false;

    

    return true;

}



Change
PHP Code:
<?php 

if ($human_readable)$ark_name = $settings->_contentDir.time()."_".$folderid."_HR.tar";

else $ark_name = $settings->_contentDir.time()."_".$folderid.".tar";



$ark = fopen($ark_name,"w");



if (!createFolderTar($folder,$ark)) {

    fclose($ark);

    unlink($ark_name);

    UI::exitError(getMLText("admin_tools"),getMLText("error_occured"));

}



TarAddFooter($ark);

fclose($ark);



if (gzcompressfile($ark_name,9)) unlink($ark_name);

else UI::exitError(getMLText("admin_tools"),getMLText("error_occured"));

To

PHP Code:
<?php 

if ($human_readable)

{

    $ark_name = $settings->_contentDir.time()."_".$folderid."_HR.zip";

    

    $zip = new ZipArchive;

    if ($zip->open($ark_name, ZIPARCHIVE::CREATE) === TRUE)

    {

      if (!createFolderZIP($folder, $zip))

      {

        $zip->close();

        unlink($ark_name);

        UI::exitError(getMLText("admin_tools"),getMLText("error_occured"));

      }

      

      $zip->close();

    }

}

else

{

    $ark_name = $settings->_contentDir.time()."_".$folderid.".tar";



    $ark = fopen($ark_name,"w");



    if (!createFolderTar($folder,$ark)) {

        fclose($ark);

        unlink($ark_name);

        UI::exitError(getMLText("admin_tools"),getMLText("error_occured"));

    }



    TarAddFooter($ark);

    fclose($ark);

    

    if (gzcompressfile($ark_name,9)) 

        unlink($ark_name);

    else 

        UI::exitError(getMLText("admin_tools"),getMLText("error_occured"));    

}

BUG with caracters:
PHP Code:
<?php 

function getFolderPathPlainAST($folder) {

    $path="";

    $folderPath = $folder->getPath();

    for ($i = 0; $i  < count($folderPath); $i++) {

        //$path .= $folderPath[$i]->getName();       

        $path .= mydmsDecodeString($folderPath[$i]->getName());

        if ($i+1 < count($folderPath)) $path .= "/";

    }

    return $path;

}

In the file "out.BackupTools.php"
PHP Code:
<?php 

while ($e = readdir($handle)){

    if (is_dir($settings->_contentDir.$e)) continue;

    if (strpos($e,".tar.gz")==FALSE)

        continue;

    $entries[] = $e;

}
to
PHP Code:
<?php 

while ($e = readdir($handle)){

    if (is_dir($settings->_contentDir.$e)) continue;

    if ((strpos($e,".tar.gz")==FALSE) && (strpos($e,".zip")==FALSE))

        continue;

    $entries[] = $e;

}

There is a problem, accented characters in the ZIP file

Thank you for the fix.
Do you know if zip archive creation will work on every system?
Does it depends on some version-specific library?

I'm testing on linux. It's OK with a simple test.

My config : ubuntu 9.10 / apache 2 / Mysql 5.1
