The family archive: the network drive box, the cloud subscription or the disk in the drawer

Everything the photo-backup page argued - that a pile of copies is not a backup - returns here at full-household scale: the documents, the camera roll, the children's years, the shop's files. The three real answers each run on one variable the others do not: the drive in the drawer runs on attention, the cloud runs on the connection and the subscription, and the network drive - the small NAS the hobbyists built a mythology around - runs on the household that will treat it like the appliance it is. This page sizes all three without the forum's religion.

The NAS, demystified in three sentences

A NAS is a little always-on computer whose job is holding one or more hard drives and serving them to every device on the house network - the folder the phones back up to, the family's shared shelf, the media server the television streams from - and it works during a blackout of the internet because it never needed the internet to begin with, which the household that has lived the router-down evenings understands as a feature no cloud tier has ever offered. Its honest costs are the ones the marketing skips: it is electricity and a network socket's whole life (the standby-load page applies - a box that never sleeps is on the meter's books), it wants the surge protection the whole house's electronics pages keep preaching, and its drives want the continuous-use class the shop's drawer specials are not (the same paragraph the shop-camera guide printed for the recorder's disk). The redundancy - two drives mirroring, the RAID the box sells as its soul - is the desk's warning label, for the sentence the trade never prints loudly enough: a mirrored pair is a downtime defence, not a backup - the ransomware encrypts both halves and the flood floats the box, and the two-drive NAS is the always-available working copy that still wants a second-location friend.

The cloud and the drive, priced in the currencies that matter

• The cloud's two real meters are not the per-gigabyte sticker - they are the upload line (the plan-reading page's arithmetic: the family archive's first sync is a gigabyte-haul over a metered connection in a country of prime-time congestion, and the 'restore' direction is the one nobody rehearses until the day it must download the whole history) and the subscription's life (the tier's terms move, the account's lapse is an archive hostage situation, and the desk's standing clause: whatever lives in the cloud should have a copy that does not answer to a login).
• The plain external drive is the archive's workhorse and its oldest failure: a disk in a drawer is cold storage that only exists when someone remembers it - the photo page's monthly appointment is the habit that makes it real, and its hardware honesty is the SSD-versus-platter economics from the drives pages: the spinning brick for the volume, the flash for the grab-and-go set, and the drawer's disk spun up, copied, verified and labelled with the date, because the unlabelled drawer is Schrödinger's backup until the restore is attempted.

The decision each household can just read off

The family with kids' video and no patience: the cloud for the daily trickle (the phone's auto-backup pointed at it), one dated drive at the grandparent's as the second location - the no-box answer, which is not a lesser answer. The shooter, the editor, the small office: the NAS earns its electricity where the work is daily and the files are heavy - the team's shared shelf, the archive's always-on front, the local speed that the metered line cannot match - with the dated copy (cloud or drive) for the flood-and-ransomware sentence. The shop with the till's records: the recorder-and-backup combo the camera-system page already sized, with the drive's twin in the manager's bag rather than under the counter. Everyone who loves the idea of a server: the desk's kindest paragraph - the hobby box (the old-machine NAS the free software classes turn a retired PC into) is real and cheap and needs an owner who will read its logs; the family that runs it without that owner should buy the appliance, and the appliance without the second copy is still the pile the first paragraph exists to warn about.

The verdict, as a rule

Whatever the size of the archive: one copy the machines move automatically (the cloud's trickle or the NAS's share), one copy the calendar moves (the dated drive, the grandparent's drawer), and the restore rehearsed once in anger the way the fire page rehearses the pan lid - the difference between the three products is who is remembering on Tuesday, and the only failed backup strategy in the class is the one that trusts Tuesday's owner to be a person.
