I’ve been using this for a few months now and love it. It’s perfect for massive amounts of photos and videos (or whatever) that you don’t need to access too frequently, and at $.01 per gigabyte there’s no beating it. The catch is that you don’t have immediate access to your backups–if you want to download a backup of something you accidentally deleted, it’ll take a few hours for the file to be ready. But that keeps the price down, and I guess it’s why it’s called Glacier. 🙂 Read the post linked above for a better explanation. Anyway I’ve got a TON of media files that are backed up on there, about 1.6 terabytes worth: 13 years’ worth of personal photos and home videos, backups of my Blu-Ray collection, ebooks, misc scanned stuff…you name it. Right now my monthly bill for everything is about $16, which is a teensy fraction of what you’d pay for another online service, and it would be far less if you weren’t storing nearly as much crap as I am. So if you’re a media hoarder or you just have a lot of crap that you’re running out of HD space for, this is definitely worth looking into.
Oh yeah, you’ll also need a client that can access Glacier and do the file transfers. I tried several, and CloudBerry Explorer is by far the best and easiest to use. They have a free version (scroll down to the bottom of the page) that I’ve been using for a few months, but I just purchased the license key for the Pro version which has some really cool and useful extras like folder comparison & sync, scheduled backups, etc. Nifty!
