When you say "how do you think that would impact it", I'm not sure whether you're asking about the performance of the backup, the performance of the render, or the CONTENTS of the backup, so I'll address all of them. As long as you're not doing renders of real-time incoming video (e.g. from a capture card), I can't imagine any impact to the output of the render other than perhaps the job taking longer. Same thing with the backup, i.e. the result will be the same, but it might take longer to complete. However, since rendering is typically more CPU-intensive than disk-intensive, and the opposite is true of backup jobs even when compression and/or encryption are enabled, you might even find that your PC can handle the backup and the render simultaneously without either one taking any longer than they would if you ran them independently.
In terms of the content of the backups, Reflect by default takes a VSS snapshot of any NTFS partition before capturing data from it, whether it's performing an image or File & Folder backup. Any files that exist on the disk at that moment will be included in the backup. If the render job completes in the middle of the backup, there is no possibility that it will be included in that backup.
