Backup the Database

On bombur, go to /home/geos/WikiBackup and, per the README, run:

mysqldump --opt --user=geos --password=<password> --host=mysql.geos5.org geos5_wiki > geos5_wiki.2017Jul26.backup.sql
mysqldump --opt --user=geos --password=<password> --host=mysql.geos5.org geos5_wiki --xml > geos5_wiki.2017Jul26.backup.xml

where the date is changed, of course.

Then, gzip them for space saving.
