I've been looking for a solution on backing up my photo/video archive to a long-term cloud storage option (e.g. AWS Deep Glacier) and after trying out multiple vendors, MSP360 seems to be the easiest to setup. I was able to get things setup and started the backup in less than 30 minutes.

Software with many options (encryption, compression, retention). Freedom in choosing from many storage providers.

Ability to use multiple cloud providers and still use only a single interface managing them all.

Easy to use, even the free version is great and the overall price is not that much, It has all the functionalities needed.
