Automatic Backups
When the system performs a backup, it updates the files in the backup folder. If a file is missing from the folder (as it would be on a first-time backup), the system will create it from the live data file.
If a service has been operational for some time prior to implementing backups, you can perform a manual backup as a first step to reduce the time it takes to complete the first automatic backup. This is because the backup will only have to be updated, not created.
