When it comes to the question of storage space, you should never think about whether to use local storage or the cloud, but rather always both and then a little more, because saving just once is never secure enough for long-term storage.
If you have already done a lot of work with digitizing, you should definitely also consider the 3-2-1 backup strategy to store the valuable results, which is the basic concept of the 3-2-1 backup strategy , that three copies are made of the data to be protected, the copies are stored on two different types of storage media and one copy of the data is sent to an external location.
The external location can of course also be a cloud.
