Koofr

Pros: I use Koofr on daily basis and really appreciate the zero-knowledge Koofr Vault for my special files. But mainly I use automatic phone backup of my photos and videos, since my phone storage is always full. I was using their free 10GB plan for a long time, but last year bought a 100gb plan and works really well.

Cons: While mobile app work really well, there could be more features.

Overall: Koofr is a great choice for day to day saving and sharing files. Can't imagine not having an access to my files on the go.

Pros: Easy to use.
Secure.
Fast speeds.
Great support, even though it's email, it's quick.
In a privacy friendly jurisdiction.
Feature rich and always improving.
Privacy orientated.

Cons: Lacks Zero Knowledge Encryption.
Has no live support.

Overall: It is the best cloud storage solution compared to most competitors. I love how they are pro-privacy, keeping my data safe and confidential. The support staff is always helpful. It integrates well with Office 365, OneDrive and Google Drive. I HIGHLY RECOMMEND.

Pros: It is very interesting to be able to connect our Dropbox, google drive, Amazon and iCloud accounts into a single service with which we can send data from one of these services to another so freely. It is a good option when you need to save space, and to be able to access data stored on various platforms from a mobile or desktop access alike.

Cons: Koofr limits a lot the capacity you can get depending on the plan you choose, so in case you need to be able to upload files irrelevant of their size or format to one or several clouds at the same time, it is almost mandatory to be able to buy the advanced versions of the platform. It takes a long time to synchronise all services.

Overall: Koofr is basically a filtering system that connects all the main cloud storage platforms, so it can be used both to gather information that is scattered across different platforms, and to upload data to the cloud and free up hard disk space.

Pros: Koofr can integrate to all major cloud services on the web, so there is no difficulty adding documents that are within platforms like google drive to share and send them to some other service, which makes Koofr a kind of intermediary service to avoid losses, among other uses.

Cons: Koofr automatically synchronizes all our data in the cloud, so in case you want to delete any specific file you must do it separately, resulting in a huge effort. The ideal would be to be able to choose what types of files will be automatically chosen by the system before uploading them to the cloud.

Overall: Koofr is one of the best options to avoid losing information from our hard drive by exporting all your data to backup copies in the cloud, which is positive in case of loss of physical work equipment. This mode of saving in the cloud has continued to evolve, and will remain for much longer, so it is advisable to use it.
