Backing Up Wiki

According to this there are three different things you want to backup:

• Database dump, e.g. mysqldump -h hostname -u userid -p --default-character-set=whatever dbname > backup.sql
• Create .tar of file system, which contains images and local config settings, e.g. tar zcvhf wikidata.tgz /srv/www/htdocs/wiki
• XML dump, contains content of wiki, technically a subset of the information in the database backup but it's good to have in case the database backup becomes unusable due to version issues or whatnot. See instructions below:

<SSH into server that runs the wiki>
sudo docker exec -it mediawiki_mediawiki_1 /bin/bash
cd maintenance
php dumpBackup.php --full > /tmp/dump.xml
exit
docker cp mediawiki_mediawiki_1:/tmp/dump.xml /tmp/dump.xml
<now copy it somewhere safe> 
also backup images on occasion using:
cd images
tar -czvf /tmp/images-2-5-22.tar.gz .

for images, cd .. and do

tar -cipzf wiki_images.tgz images/
