This is a plugin for DokuWiki which enables you to backup the most important parts of your site; this includes all of your pages, all old revisions, meta data, subscriptions, media files (your downloads), as well as your plugins and templates.
This is in case, for some odd reason, your host accidentally loses all your files; it's happened to me personally twice, on two different hosts since I began using DokuWiki– and backing up manually can be quite a nightmare.
To access the plugin, make sure you're on the admin account, and click the admin button on your wiki site.
An entry named “Backup Tool” should be listed in the the available administrative tasks. Click it, and you should see something like the following image below:
Simply check the items you wish to backup, and uncheck the ones you don't. For instance, you may not care about old revisions of documents, so you don't have to include them if you don't want to.
Click the Create Backup button, and the process of backing up starts. For large sites, it may take some time; it may even time out– in which case you may wish to backup each section individually– though this is unlikely. It will usually take at least a little time for the page to respond, so please be patient.
The backup file is generated and put in the root of your media directory. So you're then able to download it from there, and you may wish to delete it afterwards.
As a plugin all you need to do is unpack the file into the lib/plugins/ directory (you should end up with a lib/plugins/backup folder.)
To upgrade, remove the original lib/plugins/backup folder, and install the new version as instructed above.
Here's what's new:
I've finally gotten time to check the new ACL compatibility.
As it turns out, I was mistaken– ACL file names and structure have not changed, simply the interface to modify ACL has, and this does not affect backuptool for DokuWiki at all.
Therefore backuptool for DokuWiki will work regardless of the DokuWiki's version.
So in other words, the April 7, 2007 version will work, and is safe to use.
Hi everyone, let me state for the record that “tarlib”, which is part of DokuWiki's core, currently does not generate working tar files in all situations.
I've discussed this on the DokuWiki mailing list several times, and have filed (if I recall) at least two bug reports about it.
Here is a version that attempts to use tarlib (part of DW) to write the archive directly into the media folder. The tar file it creates for some reason seems to be corrupt (or at least it won't verify in my local archive manager, 7-zip.) I suspect it's either:
I'm not horribly sure but I can't guarantee I'll be able to fix it in a timely manner, so if someone would like to investigate, I'd appreciate it.

I've done some testing since last night…
— Terence J. Grant 09/17/2006 12:29
A little better, but still has the same problems:
You'll need to make a “tmp” directory in your data directory and chmod it 777 to test it.

Hi all, I've gone ahead and put a list of all the known issues below; each of which is solvable, but currently still outstanding. Feel free to help me complete these early– it'll result in a faster release and more time spent on other projects. — Terence J. Grant 07/29/2006 05:44
If you're aware of any important files I'm missing in the backup process, please list it below as file paths, thanks. — Terence J. Grant 07/29/2006 05:28
Hello, I would appreciate if your tool could also backup conf/mime.conf. Some plugins like freemind need to have changes in mime.conf.
Anyone have an idea on how to display the page as each individual section completes? I believe I'm doing everything right in this regard, but obviously the sever still wishes to wait until the page is completely loaded. So any help on this would be appreciated. — Terence J. Grant 07/29/2006 05:28
For the archiving commands ('tar') things might be a little more complex. The plugin manager includes two PHP classes, tarlib and zip.lib, I only use them for extraction in the plugin manager but a quick look makes me think they can handle archive creation and compression.
Ok, I'll look into this as well. — Terence J. Grant 08/20/2006 20:42
My other ideas are:
if a current backup exists, add option to only download that backup. For this, it might be necessary to be able to determine what file types are included in the backup.Hmmm, I think keeping the current backup around (or accessible to anyone but superuser) would be a security risk… password hashes, pages with permissions, etc could all be compromised. — Terence J. Grant 08/20/2006 21:08I wasn't thinking of it being generally available. Perhaps the installer could create a protected “backup” namespace in the media tree. Or perhaps it is a bad idea. — Chris Smith 2006/08/21 19:44
I'm prepared to help out with these changes if you don't mind.Anything you'd like to do, feel free. I'll try to improve some things when I get a chance as well. — Terence J. Grant 08/20/2006 20:42It's necessary to set an appropriate access rights for the namespace wiki:backup, to prevent unacceptable data leaks. For example no access for @ALL. While the plugin installer doesn't do it by itself, it's better to change access rights immediatly after the first use. — Alexander Sorkin 02/04/2016 18:49
In reply to some of your other points above:
* `date "+%W"` included in the file name will add a week number. Do
man dateto see the other format codes. e.g.'tar -rf backup-`date "+%W"`.tar '.$conf['olddir']
You will probably need to escape the backticks or change the quote marks from double to single to ensure PHP passes them to the shellI was thinking of using the PHP date function originally, since myself I do backups fairly irregularly. (Sometimes I'll do twice in a day if i've had some significant changes.) The only concern I had was regarding replacing slashes in the date with dashes or something — Terence J. Grant 08/20/2006 20:42
date will work too. Try something like,"backup-".date("Ymd-Hi").".tar"Okay, I'll take a look at that. — Terence J. Grant 08/20/2006 20:42
The plugin manager stores information about any plugin it installs, including the source URL. Update, simply attempts to retrieve and reinstall the plugin again from the same URL. At this time there is no intelligence behind it, i.e., it doesn't know if the plugin has been updated or even if the URL is still live.
Cheers — Chris Smith 2006/08/20 23:57
Thank you for your backup tool! Any plans to make automatically make daily/weekly backups or the option to send the backup to a certain mail address?
I personally don't have any plans myself for this– feel free to add options and send them to me (see svn for some tips.) Automated backups could be done with what's called a cron job, but most people don't have access to this.
As for mailing; I wouldn't know how to begin, though I suspect this might be easier. Again, contributions (within reason) are welcome.
— Terence J. Grant 08/22/2007 17:08
I have downloaded this plugin and all went okay, but when I process the backup I should find a back-up file in the root (“The backup file is generated and put in the root of your media directory”).
But there is no such file. What can be wrong? —FJH Langendam 08/20/2008The file should be created in the “root of your media directory,” so this does not mean your “file system root,” this means the top level media directory.
In other words, it should be creating a file in your “data/media” directory. Is this not happening? — Terence J. Grant 08/20/2008 23:08
I've tried it again and although DokuWiki shows the name of the bu-file (DokuWiki-backup-20080821-220132.tar.bz2) it's not in the dir (httpdocs/doku/data/media). — FJH Langendam 08/21/2008Hi FJH,
There's a link generated on the BackupTool page, I'd suggest using that to get the file.
I'd also suggest using the media manager to delete the file.
Hope that helps,
— Terence J. Grant 12/20/2008 17:03
Hi Terence and thanks for your updates of this plugin.
I've just launched a new wiki at some site the PHP of which announces availability of bz2 but fails on generating anything bz2-y (also old revisions cannot be generated with bz2, e.g.), so I had to hack the code to force gzip compression. Would you consider adding the compression-type to the configurable options? (So I don't have to hack again when there's an update of the plugin.) — Andreas Wagner 11/25/2008
Hi Andreas, yes, I'll add the option as time permits. — Terence J. Grant 12/20/2008 16:56
I suspect that when the option 'media files' is selected, backup-tool tries to backup the previous backups. Here is my quick solution.
if (!bt_exec("tar ". (($i != 0) ? "-rf " : "-cf ") .$tarfilename." ". "--exclude dw-backup-* " . _getRelativePath($item)))
- Can this tool be used to migrate data from one instance of DokuWiki to another instance running on some other host?
- Does this tool work for Windows?
- (also side note: anyone know why my H2 is not being properly rendered by DokuWiki? Is the a maximum size to a page? Is there some syntax error somewhere above me?)
— Peter Thung 12/16/2008
- Yes, it should be able to. There is some manual configuration that will need to be done to restore, but it's very minimal.
- It will work on Windows if you do one of two things– you'll have to decide which is easier to configure, though):
* Install tar and gzip (or tar, gzip, and bz2) via Cygwin for Windows and make it available to the server. (Or use a similar method to make tar, gzip2
* Install Pear for your PHP installation.
- Usually these are syntax errors (mismatched “=====” or “**” signs for instance), but these are questions you should ask on the DokuWiki forum.
Best of luck,
— Terence J. Grant 12/20/2008 16:56
- First thanks your the response.
- When you say there are some manual configuration that will need to be done to restore, but it's very minimal, may I ask what they are, or how or where I could find them? I was able to install the backup tool and run it. I apparently already had Cygwin installed and the tool seems to work as I saw the archive created. I looked into it and saw that it appears to just backup a few directories. Would the general procedure be to shutdown Apache, delete the physical directories then manually untar/unzip the archive to replace the directories you deleted?
- In regards to installing targ and gzip for windows and making it available to the server, if I do have Cygwin installed on my windows box, is it just a matter of making those executables included on the windows Path environment variable, or is there another way? I guess the Windows path thing was enough.

The following assumes that your Wiki is completely gone - you have nothing left then one backup-archive and the credentials of the Admin-User.

Hi, in admin.php line 225, where the file gets saved, the plugin does not respect the setting of savedir to find the media directory. I changed the path to: “$conf['savedir'].'/media/'” and now it works. I suppose this is the intended behaviour. If not, trying to save in the wrong place can give permission problems as well as saving in the wrong place.
thanks for this plugin… greets, naja
I get an “Access Denied” message in an XML file when requesting http://cloud.github.com/downloads/tatewake/dokuwiki-plugin-backup/backup-stable.tar.gz. :(
— Marcus Gnaß 10/20/2009
Same here, the link is not working. All the best, heinz
I also had problems finding it. Note name difference above good link: from backup → backuptool
Thanks for the plug-in,
I get no errors or warnings until I try to click on the link where it says file not found. I also do not find it using FTP…(hosted on byethost.com)
— Mikael 11/09/2009
I have earlier asked for the solution of not finding the backup file. When I use the generated link, the anser is a HTTP 404-page as the link is: http://www.myurlname.org/doku/lib/exe/fetch.php?media=dw-backup-20100508-195001.tar.bz2
Offcourse the data/media-dir has rights (777).
I hope to hear from you.
Hmmm…newest backup stable version (really should display the actual version number on some page). on VMWare → Linux 2.6.9-42.ELsmp
Says that it is failing, but is actually creating the TAR…just seems to not zip it? Is there some “use zip here” parameter? — Michael Quinn 2010/07/07 20:06
I install the plugin from the Plugin Manager and I found estrange files inside the plugin directory. I think it may be from some Mac OS system because I see that before when someone use my pendrive in that OS.
The list of files is: ._admin.php ._.DS_Store .DS_Store ._lang ._pref_code.php
It seems this plugin hasn't been maintained for a while, and some issues have built up. In particular I the old version didn't respect $conf['savedir'] or DOKU_CONF being located anywhere other than the default locations. I've put up a forked version ( https://github.com/marklundeberg/dokuwiki-plugin-backup/tarball/master ). I also added a feature for putting the backups in a folder other than media root, so you can use ACL to control access to old backups. Also, a feature for viewing and easily deleting old backup files. I'm going to add a link to the top of the page, and hopefully get a pull request going. — Mark 2011/03/07 07:16
While it's true I'm not keeping this project up-to-date, I'd suggest pushing changes to the original repo rather than forking it. I'm getting emails from users about multiple repos containing the same code. Push changes to me and I'll approve them. Thanks in advance. — tatewake 2013/10/06 05:34
First: props to you for picking up this plugin and even expanding it! Unfortunately, it does not seem to work properly, it always goes to a nearly empty page saying “The backup tool is working, please wait…”. This lasts forever (ok, for more than 15 minutes, where the old version was ready after 15 seconds) and the backup is not created. I left the preferences at their default values. Is it maybe necessary to create the namespace wiki:backup? — Cantello 2011/03/15 17:35
