How-To Backup Wiki

To back-up this wiki involves these steps. Note: This procedure includes a full MariaDB backup.

First, log-in as "root" or do "sudo bash". Then run a script similar to the following.

Replace /backupdir with a full path for a non-existent backup directory. Make sure that there is at least 1 GB of disk space free in the associated filesystem. Set DATE6D to a 6-digit date.

set -e
mkdir /backupdir || exit 1
cd    /backupdir/
#
DATE6D=240709
mysqldump -A > mtwiki-$DATE6D.sql
mysqldump --system=users > mtwiki-users-$DATE6D.sql
gzip -9 *.sql
#
tar zcf mtwiki-tree-$DATE6D.tgz /var/www/wiki.minetest.org/
tardate *.tgz
ls -l

Note: The "/*" in one line above is needed because the directory above that may be a syslink. This will cause top-level dot-files to be skipped but as of Fall 2023 there weren't any.
