Using SyncBackPro > Expert Mode > Simple, Performance

This page shows you which settings may be affecting the performance of your profile. It is important to keep in mind that speed is not everything, and that what is more important is that the files are copied correctly. For example, verifying that your backup files are correct will slow down the profile but will guarantee your backup files are not corrupted at backup time. The safe copy option is enabled by default for most profiles and it is strongly recommended that you do not switch off this option just to slightly reduce the backup time.

You can jump directly to the appropriate settings page by simply clicking on the items listed in the "The following settings are slowing down the profile:", etc., sections.
