Functionality
BackupWordpress is a nifty little backup plugin. Once installed, you need to got to Sidebar > Tools > Backups to access your backups.

All backup schedules are shown here. This is pretty good as you can make different backup schedules for, say – taking a database only backup weekly and a full website backup at the end of every month. These backup schedules will show up over here.
To create a backup schedule, click on the ‘+ add schedule’ button on the top bar.

Here, you can customize the backup frequency, type of backup and email notifications. Note that the files + database backup can be pretty resource intensive and should be run sparingly.
Scheduling backups is very straightforward. You can create as many backup schedules as you want. Ideally you may want to take a database only backup every week and a full site backup every month. You can also customize the number of backups to keep in storage.
