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
  • 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 =)
