A plain map of Whitcombe & Farr's copies: the live server in the back room holding records, x-rays and accounts; a copy nearby that keeps the past — last night, the night before, last week; and a copy far away, out of reach of fire, theft and ransomware. Below, the image sync's green tick is shown to be a mirror that would copy an encryption in seconds, and the nightly backup that ran for years restored corrupted images the first time it was tried, until it was fixed and the restore proven.

What you'll learn

Say what a backup is, and tell it from a sync, a spare drive, and a reliable live system.
Keep more than one copy in more than one place with one out of reach, so ransomware cannot encrypt it.
Test a restore before you need it, and tell 'the backup ran' from 'the backup works'.
Notice when a backup has silently stopped, and keep it real with the four dull checks and a named owner.
