I’m looking for a diskspace of possibly 1TB online
Edit: my idea is to use it like as an external harddisk for everyday stuff. Encrypt the disk, put my filesystem on it, mount it as external drive kinda. Never worry about backups or lost data etc, as the provider would take care of it
(preparing for inevitable downvotes) depending on how much storage you need and the flexibility you have in how you use it, Office365 includes 1TB of OneDrive storage for 6 users for somewhere around $100/yr. I use it for storing encrypted video files from my NVR and it works for my use case, but ymmv.
