Just noticed the “backups” tab in the Admin area - do I need to do anything to backup or is it done automatically?
Your database is backed up automatically daily. The default is weekly, but apparently I changed it to daily. It keeps 5 backups by default.
This keeps a backup of your database, which includes everything except which plugins you have installed, on your host. To be more paranoid you might have a copy kept somewhere else (or implore me to do so).
You can see your backups on the backups tab and find the backup settings by searching settings for
backup or by clicking the backup tab.
