Thanks! Side question, but how is Amazon Glacier consdiered affordable? For 4TB it costs $192/year... yet you could buy two 4TB HDDs at that price yourself and use one for redundancy and the other for immediate retrieval. What's the benefit of putting your data on Glacier when it costs twice as much as keeping it yourself, and probably takes longer to retrieve too?
Like the rest of Amazon (excepting the Cloud Storage, which is all-you-can-eat for personal use only) - it's not affordable. Unless you might need 400 4TB drives, and keep track of which one have what on them, which are up-to-date, which are in which fire/disaster zones etc. At that point the price starts to look more reasonable.
But can't you put your own hard disks offsite somewhere? Just because you're holding your own backups that doesn't mean you have to be keeping them at the same location.
