To heck with it - after reading the previous deal and then finding this cheaper deal via StackSocial, I bit. Got it for US$35.10 using the "FIRST10" discount code. So roughly AUD$48.50 all up.
My plan is to use it to have another offsite backup for my photos. It will not be my only backup of course, but if they hang around for more than a year or two I reckon it will be cheap insurance and I'll be in front. Absolutely it would be even cheaper to just use Amazon glacier directly. Currently that costs $0.012 per GB to backup to Sydney. All up then, 1,000GB would be $12. The trick though is restoration - that costs $0.14 per GB, although the first GB per month is free. IF all my other backups failed and I had to resort to using this to restore all my images, it would take roughly 83 years to copy it out at 1GB per month or $140 to get that 1,000GB out a little quicker…. so for an extra $20 or so I'm getting the ability to copy out as much as I want (within the restrictions of my bandwidth) plus the handy interface with the set and forget backup.
So, installed the client on my mac mini (that's always on), pointed it at the photos directory on my qnap, and it's backing up now!

I'm surprised this isn't Lifetime* Storage just like the old Unlimited* internet plans.
