get yourself another drive ASAP and rotate them
That's about the best we can do. Of course, if we'd just create less world-changing files/documents, we could keep all those GBs of data on a floppy!
But I've got to get busy sharing my monumentally important data so the universe can benefit from my skill. In the meantime, I need to buy YAGD* to back up the back up so I can reformat it so I can back up the new back of my new internal drive that I reformatted as a single partition since I never get the two sizes right, anyway.
And then there is Judy's backup drive...
And our granddaughter's MBP...
Can you imagine what it must be like to maintain backups of backups of backups of ... For most any business?!!!

BTW, I assume you will let OWC know that they will be expected to honor their warranty. One week can be wasted in shipment!!!
But I'd also recommend buying a separate drive and enclosure for at least two reasons:
1. You will automatically get a longer warranty on the drive itself.
2. You can specify the drive that you buy. Buying the preinstalled combo may not let you do that, even OWC needs to make a profit and most drive last well past their warranty. But the cheaper ones mean more profit...
I'm just say'in...

ur Apple store(independent), will match any price I come in with and order it for me.
Great, if you can open the door to their store, you can put a drive in an enclosure.
Not sure I understand why you would want to even involve them, however. Just adding more 'middle-men.'
Would you call your electrician to come replace a light switch for you? (I know, your husband IS an "electrician!")
Sure, if you don't have the time or inclination to use a screw driver, someone else will be glad to do it for you and accept a small profit for doing it. You, however, don't appear to have a 9 to 5 job...
You can assume anything you like...
But I think I've found exactly what you need! It uses a Hitachi 3.5" drive, also. While it doesn't have FireWire, it is darn near fire proof! <ioSafe SoloPRO Waterproof / Fireproof USB 3.0 Hard Drive>[attachment=1999:iosafe_s...ive_fire.jpg]
