I have three tiers of backup. Never heard or the 3,2,1 rule?
3 backups 2 locations 1 offsite
I backup one time on an external disk connected to the server. A second time to another disk, connected on an OpenWRT router located in the patio. A third copy is uploaded to my VPS in the cloud.
not all three are symmetrical due to disk sizes. But critical data is always backed up on all three. Daily backups.
Restic do deduplication and encryption too, so actual data usage is really minimal and all is kept safe.
