How on earth do I unlink computer

[henrikvartaget]

I make backup of NAS dato to iCloud. Doing that I want to transfer 300 Gigs at the time to MBP and from there, from MBP to iCloud (2 TB space). Afterwards I need to make space om MBP to new data - but when I delete the first serie of data om MBP, it be deleted on the cloud too.. what to do here..?

I don't think it is a good idea to use iCloud as NAS, it is a very poor idea. iCloud is supposed to sync, so if you delete items it will delete across devices. If you accidentally delete a file, you will accidentally delete the backup.

My advice (like mikecwest's) is to NOT rely on the cloud for backup.

Your BEST backup would be a bootable cloned external drive created with either CarbonCopyCloner or SuperDuper. Right there close-at-hand if you ever have one of those "I can't boot" moments of extreme need...
