Backup architecture in practice and other considerations

Appreciate the feedback, thanks! :slight_smile:

  1. Okay, so what you’re saying is, that you backup your stuff to the NAS and then you create backups from the NAS itself? That seems to be a reasonable approach. I always had the model in my mind that all backups should be identical so that they can be automatically compared etc. But that might be not necessary at all.

  2. I searched the docs and found it here: It is actually recommended to run restic check after each backup that there are no errors in the metadata. Interestingly this is more or less the only point in the restic doc where this is mentioned. On the other hand I know found this thread, from which I would take that this is pretty useful. Essentially restic check --read-data appears to substitute/automatize the process of test restores and scrubbing.

  3. Well, interesting. I had a look again and I think the 3-2-1 rule means that there are 3 actual backups in addition to the original. In my case that also makes sense because I can not guarantee that the original data is deleted by accident.
