A NAS is not a backup medium, but at most a duplicate memory.

Data backups are not permanently made available on the network, but kept separately in a safe place.

A backup should always be on another device.

So if you play a backup of your PC to a NAS, it is completely i.O. => 2 devices.

If you play a backup from the NAS to the same NAS, it would be just a device.

I didn’t write “External Connecting”.

So a real backup should not be in the NAS, but externally in another safe place.

But the NAS has set up to run multiple disks as RAIS, so that one can break and you don’t lose any data, that’s right, but doesn’t really mean backup.

If the record is in the same system as the original files, you are only secured if you want to look into old file versions. If the NAS burns through, it is successfully attacked and encrypted, for example, you have water damage, fire, whatever, you don’t use the backup because it is affected.

A real backup is only if you play it weekly, or whenever, on an external storage medium and where it is different.

No.

Not really. The backup medium should be separated and kept separately.

A backup disk still needs care, because hard drives and SSDs are not long-term storage.
