Is there a cloud aggregator of Cloud file storage services for file backup?

Question

Google Drive

The point is this.
We've been flooded with Dropbox, Google Drive, OneDrive, Box.com, Copy.com, and more.
But storing something important in one cloud would be reckless. There is no guarantee that none of these services will close tomorrow.
Perhaps there is already a service that aggregates third-party services? And uploaded it once, and the files were copied to Dropbox, Google Drive, OneDrive, etc.
Those. something like cloud RAID will turn out. Conditionally speaking.
Those. why not use all the services that are available at once?
Are there already similar services?

Answer 1

it is doubtful that they will close of course, and I would store something really important on a flash drive)
on Windows there is such a thing rei.to/carotdav_en.html a client with the ability to connect different cloud storages
