What exactly does wordpress store in a database? eg. if you didn't back up a database (only exported files via admin panel) what would you lose when trying to restore the site?
Get wp-backup - free plugin. You can backup on demand and save the file to your PC, the server or have it emailed somewhere -and- you can schedule a backup. I schedule a daily backup to be sent by email to a gmail account - that way, say, if I were on holiday and lost the lot I could still rebuild it from wherever I was. Note: if you then add further plugins to your site functionality, make sure you remember to pop into wp-backup and add the new tables to the backup schedule.
What is name of plugin and where to get that plugin. Any link to that plugin will appreciated. Thanks,
