Build a backup plan that can survive ransomware
Decide what must be recoverable, keep at least one copy away from the everyday system, and test restoration before the files matter.
Name what must come back
Photos, tax records, identity documents, and the working files you cannot recreate. A backup of the whole disk is useful only if you know how to restore the pieces you care about.
One copy offline or out of reach
A drive that stays unplugged, or a cloud copy with versioning that cannot be wiped by the same login that runs the computer. Test a restore of one folder. An untested backup is a hope, not a plan.
Limits
This does not replace incident response after an attack. Next step: a written list of what is backed up, where the offline copy lives, and the date of the last restore test.
