AWS Makes Sense Now

Love this program. I've always struggled managing vaults and archives etc on AWS S3. I also don't know how to write scripts to use AWS. I don't need to now. I've got Freeze. This is a fantastic app to help you back up all your stuff. I do monthly backups for my company and yearly backups for work plus personal in addition to Dropbox and Time Machine. AWS is great long term storage and Freeze helps me use it with ease. Thank you!

Great solution

Been using for a couple years now - very good solution for uploading huge archives and disk images to Glacier. Some previous stability and reliability issues have long been resolved. Spending $ on this software is a bargain, and generates a strong ROI, because of how it lets you take advantage of cheap cloud storage.
