Backups for the laptops and desktops at home
Three copies.
Two kinds.
One away from home.

The rule fits on one line
- 3
copies of every file you care about
The original on the computer plus two backups. One backup is a single point of failure.
- 2
different kinds of storage
Say a drive at home and a cloud backup, so one kind of failure cannot take every copy.
- 1
copy away from home
Past the front door, so a fire, flood or burglary at home leaves one copy standing.

Work lost if it failed today: up to about an hour
A sync folder copies every change straight away, including deletions and files scrambled by ransomware. Check how long your service keeps deleted files and older versions before you count on it.
Next stepAdd one more copy so there are three in all: an external drive at home is the usual choice.

What this site never does
- Never touches your computer. No download, no remote access, no scanning. You type what you know.
- Never stores your files. It is a plan, not a backup service, and sells no storage.
- Never asks for passwords. Password-shaped text is refused.
- No account, no email. A map opens with a private link that only you hold.
