We recommend scheduling your backups for times when the traffic on your site is light. The following are recommendations for Database Only and Complete (Full) Backups.
Database Only Backup: Weekly
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.
Complete (Full) Backup: Monthly
BackupBuddy recommends doing Complete (Full) Backup every 2-3 weeks since your files only change when you add or upgrade plugins, themes or your WordPress version.
