Backing up this Wiki

This is the research completed at the digital gardening bee 30th June 2018—it is yet to be implemented:

1. Use mysqldump to make a backup

https://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki#Mysqldump_from_the_command_line 2. You’ll want to save to a different filename every time, e.g.

nice -n 19 mysqldump -u $USER --password=$PASSWORD $DATABASE -c | nice -n 19 gzip -9 > ~/backup/wiki-$DATABASE-$(date '+%Y%m%d').sql.gz

You can skip the “nice -n 19” parts of this command, but the useful part is the date.

3. Test that the backup works

https://www.mediawiki.org/wiki/Manual:Restoring_a_wiki_from_backup

I’m not super clear on how to test.

4. Passwords are hashed and salted, so it’s probably ok. Use scp/sftp to copy, e.g.

scp wikifile.gz remote.server:~/backups/

5. You can put all that in a batch script and then use crontab. See
