Use cases

The same three-copy rule protects a family's photos and a hospital's records. Here's what it looks like for each.

For people and families

Phones get lost, stolen and dropped in water. Every photo should already be in two other places.

Property papers, certificates, insurance and ID scans, backed up only when you choose to.

Photograph a bill once. Find it again at tax time, for a warranty claim or a reimbursement.

Keep a copy of every mail from any IMAP mailbox, even if the provider locks or closes the account.

Your books, GST invoices and billing data live on one PC by the counter. Keep two more copies, automatically.

Immutable copies the attacker can't encrypt or delete, even with your admin password.

Client files kept for the years the law requires, with an audit trail of who restored what.

Patient records and imaging backed up in India, with a disaster-recovery copy abroad if you choose.

Point pg_dump, mysqldump or restic at one endpoint and get multi-continent copies for free.

A third copy outside your primary cloud, on another continent, with your keys and your retention rules.
