We used Pagefreezer for their unlimited plan, we really loved that they were so flexible with the price, and how easy it was to integrate. The interface is nice and clean, but not very user friendly. Their support team did not seem to be as helpful as I would have liked. Also, we had an issue with our pagefreezer account being hacked which wasn't addressed until after we had already made the purchase. So we ended up giving up on Pagefreezer's service and went back to Google Drive instead. Try it out first! They will work with you during your trial period.We were using Google Drive to help keep all of our important files in one place, but we needed a way to automatically archive older versions of those files in order to comply with our legal requirements.
