Backing Up Wiki

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

1. Database dump, e.g. mysqldump -h hostname -u userid -p --default-character-set=whatever dbname > backup.sql
2. Create .tar of file system, which contains images and local config settings, e.g. tar zcvhf wikidata.tgz /srv/www/htdocs/wiki
3. 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. Performed using command-line tool dumpBackup.php, located in the maintenance directory.
   1. SSH into server that runs the wiki
   2. sudo docker exec -it mediawiki_mediawiki_1 /bin/bash
   3. cd maintenance
   4. php dumpBackup.php --full > /tmp/dump.xml
   5. exit
   6. docker cp mediawiki_mediawiki_1:/tmp/dump.xml /tmp/dump.xml
   7. now copy it somewhere safe =)
