GoFlex Drives as Backup Drives

[Earwax]

I have a pair of 1.5TB GoFlex external drives that I would like to use to backup 3TB of project data. I'm a video editor and I have a pair of RAID 0 2TB drives at home partitioned into two main drives. One of the 1.5 TB RAIDs I use for current projects, the other 1.5 TB drive holds my project files, media managed projects, and master outputs.

What I'd like to do is a bi-weekly backup of each of my internal 1.5TB partitions to my 1.5TB externals, which I would be storing offsite. Is there a good software solution for this usage?

Everything I've encountered so far has referred to using NAS or windows backup. I believe I tried using windows backup several years ago, but I'm not looking for a program that is going to re-write huge chunks of data that is already there. Ideally I'd be using a program that would simply detect the changed files from the last backup, and adjust each external drive accordingly.

I'm running win 7 professional 64 on an evga X58 LE. I have 2 1TB WD Blacks as my RAID 0 boot and work drives (500GB boot, 1.5TB project storage) and 2 1TB WD Greens as my RAID 0 long term backup partition (500GB Music, 1.5TB Project outputs).

I'd appreciate any advice.

Cobian (free) backup will do just this. You can set it up so that every X or Y days, do a full backup and in between do a differential ones. I can do compression with password etc. For data, I don't see a better one that this after trying a bunch of different programs (free and commercial).

I backup 1.5TB of data (pictures) from my computer to a USB3 external (mybook) like this:
Monday/Thursday - full backup.
T/W/F/S/S - differential backup.

In my pictures folder, I created a dummy file named "Full - backup". This file never change so it only get backup no M/T. This help when I look into the WD drive, I know which backup set is full and which one is not.

the goflex drives would heat up and flex literally and disconnect after a long period (3TB worth) of copying. had to return them. the plastic base and drive would expand.

got the cheapest 3TB single unit usb 3.0 and it is solid filling it up for offsite.

big fail had to return 3 GOFLEX because they FLEXED and disconnected lol.

Thanks guys,

I'm in a bit of a bind financially so I'm just going to have to make it work with the goflex drives for now. I'm gonna give Cobian a shot. I don't have much faith in externals, which is why I don't want to trust them for any non-redundant data.

Down the line when I'm a little more secure with my wallet I'll probably try a service like carbonite.
