OK there are no backups. I might have to do some myself.

I think the following things need backing up:
announcements/
info/
atom_feed_log
seen_issues_log

OK, I've set up backups.

Every day, cron makes a .tar.gz of the above listed files and directries in pbot-ng's home folder, overwriting the previous archive.

Also once a day, I download the most recent archive from the server to my own computer over ssh. Then I check it's last modified time to make sure the archive was made within the last day.

I've written a new bug tracker change detector so I no longer need to back up `atom_feed_log' or `seen_issues_log'.

The cron command that runs daily to make the backup is:

@daily tar -czf pbot-ng_daily_backup.tar.gz announcements/ info/
