How do I backup my files onto more than one hard drive?

[HSakols]

Now that I have almost filled a 3 TB external drive as my back up, can I use my back up software (SuperDuper) to make one back up over two external drives give me 6 TB of storage?  Is this possible?

I guess what I'm asking is it possible to split a my large hard drive into multiple volumes so that it can be copied  onto two smaller hard drives.  Or is it best to buy a new larger hard drive so everything is in one place?

Yes you can repartition your hard drive into multiple volumes, each of smaller size. But I think it's easier to tell your backup program to send directories A-M to external 1 and N-Z to external 2. I don't know if super duper can do this (it's billed as a whole drive cloning program) but other backup programs can do this no problem.

However, I would probably just buy a larger hard drive and relegate your older 3TB drives to secondary or tertiary backup.

 Exactly what I do...

Thank you, that really helps.  I found an 8TB drive for under $400.00.  It is just that I have so many hard drives just sitting around.  I may take one of the oldest ones to the shooting range.
