Is there a 3rd party mac app for this?

[Pmj60627]

I have a G-RAID 6TB External HD and I just purchased a G-SAFE External Hard Drive. I was wondering if there is any form of software out there that would make it possible to do the following:

I want to continue using my G-RAID as my main external drive and, every time I add something/save something to the drive, I want it to instantaneously back it up to my G-SAFE. Being that I work in film, having a double back up to my digital files is really important.

Is there a program that somehow links the drives?

I don't have a specific App for you, but you might want to check Mac Update. Whenever I am looking for an App, this is the place
