Wiki Backups

Wiki Backups have a number of uses, including preperation for when the Internet goes out. Having access to information is an essential aspect of the modern world. There are many ways you can access WikiMedia archives, as well as render them.

MediaWiki Based Sites

You can create your own viewable and offline backup of most MediaWiki wikis (i.e. anything that looks like wikipedia). This is handy if you're away from your wifi connection, are too cautious to lookup certain search terms or have friends where wikis are blocked.

It's also pretty cool to have your own copy of Wikipedia.

Usable Offline MediaWiki Backups

To create an accessable, offline wiki backup you need two things:

1. A dump of the wiki, often compressed into a single file (sources below).
2. A program to access and search the compressed wiki file with.

XOWA is a cross-platform, AGPLv3 licensed program to view wiki dumps with. It's simple to use and pretty easy to setup. Wiki dumps need to be imported before use, and on an i7 running at 3.4ghz take about 1mb/sec to import. So about a minute for WikiVoyage and half a day for the full english Wikipedia.

Creating Usable MediaWiki Backups

MediaWiki based wikis (like this one) can be backed up on your computer:

• tutorial via Archive Team

WikiMedia Backup Sources

WikiMedia creates backups monthly, available from WikiMedia Dumps.

• These are text only dumps.
• They backup all of their wikis in all languages.
• There are several versions of each wiki do download. You likely want the [wikiname]-[date]-pages-articles.xml.bz2 file, which they kindly highlight in bold for you. This version lacks the full edit history and details of the non text items (pics, vids etc). If you want full edit history, there are several versions available.
• Full, compressed text backup of the english Wikipedia is about 10gb.

BurnBit is a useful site for downloading large WikiMedia dumps. It's a site that can create a torrent from any url and also acts as a tracker. Paste your WikiMedia backup file url into it to create/access the torrent for it and you'll download at maxspeed.

Kiwix

Kiwix is another offline wiki viewing software that uses the ZIM format. They offer a list of pre-compiled files that can be loaded onto your preferred storage medium. Note that large files (>4GB) will need to be split on filesystems such as FAT.
