* Does anybody know a solution to make a backup only for a single blog in a multisite
installation?
* I have a subdirectories-based network installation, and wish to give a way for
each blog administrator to make a backup (DB & files) only for its own blog.

* Thanks, very useful.
But I don’t find an export way for site preferences and
files.

* ou won’t. currently there’s nothing out there to export a single site off a network.
it’s everything or the export file.
* you don’t want to give blog users access to the entire db.

* Sure, I don’t want to give blog users access to the entire network data; only
to their own data to make it restorable on another WordPress installation.

* The menus and prefs are not the data. The data is your post content and the images.
THOSE are exportable.

* I understand as user’s data:
– Published texts (Posts, Pages, Comments) – Attached
files (media) – Site preferences (menus, selected theme, title, etc.) – Plugin
preferences and their custom accessory files
* Conclusion: all information and files that single-site administrator could set,
write and upload.

* these are not included in the Export tool.
* As I said above – **there is no plugin** that does exactly what you want.

* Then, is there any way to export easily attached files for published contents?

* I think thats true in all cases lmao.

or just for yourself?

* You could make backups of each by using zipping method.
* ```
class createDirZip extends createZip {
function get_files_from_folder($directory, $put_into) {
if ($handle = opendir($directory)) {
while (false !== ($file = readdir($handle))) {
if (is_file($directory.$file)) {
$fileContents = file_get_contents($directory.$file);
$this->addFile($fileContents, $put_into.$file);
} elseif ($file != '.' and $file != '..' and is_dir($directory.$file)) {
$this->addDirectory($put_into.$file.'/');
$this->get_files_from_folder($directory.$file.'/', $put_into.$file.'/');
}
}
}
closedir($handle);
}
}
```
* then
* ```
$createZip = new createDirZip;
$createZip->addDirectory('uploads/');
$createZip->get_files_from_folder('/wp-content/uploads/', 'uploads/');
```
* and
* ```
$fileName = 'tmp/uploadsbackup.zip';
$fd = fopen ($fileName, 'wb');
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);
$createZip->forceDownload($fileName);
@unlink($fileName);
```
* this will take all of the contents of /uploads/ and zip it into “uploadsbackup.
zip”
* it might be a pain in the butt to do this for each user but im sure you can alter
the code above to do so, find users, and place the username within the `get_files_from_folder('".
$users."/uploads/` or whatever.

* you could use something like this to grab the usernames in order from newest
to oldest and if you place it in a `` you could have a nice list of all the
backups you need to download right away.
* ```
$usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 999");
foreach ($usernames as $username) {
```
* ```
$createZip->get_files_from_folder('/".$username->user_nicename."/uploads/', 'uploads/');
```
* also adding the username to the temp. zip
* ```
$fileName = 'tmp/".$username->user_nicename."backup.zip';
```

* just depends on how bad you need those backups, and or separated.

* I manage a multisite installation (subdirectory based), and need to give a way
for each user (1 user owns 1 sub-site, another user owns another sub-site) to
backup own contents.
* Of course I can backup the entire multisite directory and database, but cannot
deliver this backup to “user 1” when also contains data from user 2, 3, 4, etc.
* I see that the multisite uploaded files are in /wp-content/blogs.dir/ and I don’t
see clear separation between each site correspondence.

* my multi site works as [http://domain.com/username/wp-content/uploads/](http://domain.com/username/wp-content/uploads/)
* you can alter the code above to be specific and add the needed directory for
lets say the “uploads” and you could make a generic file for each logged in user
* and you could grab the the URL of each user by doing this:
* ```
$usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 999");
foreach ($usernames as $username) {
echo 'http://www.yourdomain.com/'.$username->user_nicename.'/wp-content/uploads";
```
* it will pump out from new to old:
* [http://www.yourdomain.com/username10/wp-content/uploads/](http://www.yourdomain.com/username10/wp-content/uploads/)
[http://www.yourdomain.com/username9/wp-content/uploads/](http://www.yourdomain.com/username9/wp-content/uploads/)
[http://www.yourdomain.com/username8/wp-content/uploads/](http://www.yourdomain.com/username8/wp-content/uploads/)
[http://www.yourdomain.com/username7/wp-content/uploads/](http://www.yourdomain.com/username7/wp-content/uploads/)
* but it will replace the username## with like the username or site name i personally
use usernames as the subdir.

* eh, after all this i should just make a plugin that would backup mutli-site users
profile, uploads, posts, pages, links, and so on. :X
