Nimbus is a dual purpose backup and file syncronisation program.
It enables you, for example, to keep the files on your PC in sync with those on your laptop. When you change or create a file on the PC then the amended or new version will automatically be replicated on your laptop.
You can link any number of computers in this way and the data is also accessible on your phone or tablet.
If you don't need the syncronisation feature then Nimbus also automatically provides a cloud backup which can be accessed securely from any web browser.
As a further precaution, the files in the cloud backup are periodically backed up to A222's own servers here in the Croydon.
Cost is £75 per 100gb (enough for most people) of data per annum. Installation is £45 for the first computer, £25 for any subsequent ones.
