I like the high availability features that Tebi offers, with its geo-replication. The best thing about Tebi is the free version that you get when using it as an add-on for your existing S3 bucket. You can use this to test drive the service and see if there are any issues with geo-replication. If you do not have access to such testing, then just go ahead and use the paid version. Not much I dislike. Not really. But since this is a software product, I would love to know what is missing in the paid version. This will make me feel better about the paid versions. The ability to set up a highly available location. And it also has a backup feature which allows us to keep a copy of our files at two locations.
