BackupBuddy: Database Only Backups
BackupBuddy’s Database Only Backup backs up the WordPress database, including:
- Widget content
- Media titles and descriptions (but not media files)
- WordPress settings information
A Database Only Backup backs up your WordPress database with less impact on your available storage space or server performance.
Recommended Database Only Backup Schedule
We recommend performing a Database Only backup to back up your database on a weekly basis, since your database changes much more often than your files and folders. Visit the Scheduling section for more information on setting up backup schedules.
