External backup based on date of folder creation

[m.uher.cz@gmail.com]

Hi,

I am a satisfied owner of AS5304T and I am currently using build-in backup app for period backup of my files to multiple external drives. However I would like a more detailed control over my backup policies, specificaly be able to select folders based on date of creation of file. For example: I would like to backup all folders older than certain date to be saved to external drive A and all folders newer than certain date t obe saved to external drive B.

Is there some 3rd party app that would allow me to do such a thing? I briefly scanned the AppStore but find no such tool.

Many thanks for any tips.
