Deletebackup

new function to delete backups:

I tried testing it, but I couldn't even create a repository or a backup (hence also not delete a backup :) ) as the instructions on how to add a "path.repo" argument to the elasticsearch.yml file (in create_repository) did not work:

• Instead of a /elasticsearch/config path the file is in /etc/elasticsearch/elasticsearch.yml
• When running:

 echo "path.repo: ["/home/felicia/es_backups"]" >> /etc/elasticsearch/elasticsearch.yml
 grep path.repo /etc/elasticsearch/elasticsearch.yml

I get

path.repo: [/home/felicia/es_backups]

So this seems to work fine...but when I then restart elasticsearch it fails to start. This is the output

Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled)

After this I actually had to reinstall elasticsearch to get it working again. So either there is some mistake in the code I ran (which was what was suggested for create_repository) or my installation of elasticsearch runs into troubles after I set the path.repo file. Extensive googling couldn't give me a solution...

Thanks for trying, @FeLoe !

Does /home/felicia/es_backups exist and is it writable for elasticsearch?

Try sudo chown elasticsearch.elasticsearch /home/felicia/es_backups and maybe also chmod 775 /home/felicia/es_backups

If that's it, we should add it to the instructions as well...

Perfect, that did the trick! I added the explanation to the docstring and also fixed some issues with restore_backup, now this also works.

Thanks a lot!
