ransomware backup protection

1. We already have backups. Are they automatically ransomware proof?

No. Regular backups on the same network as production data can be encrypted along with everything else.

2. How is immutable storage different from a normal backup?

Immutable storage cannot be altered or deleted for a set period, even by an administrator account.

3. Do we need air gapped backup if we already have immutable storage?

It adds a fully disconnected fallback, useful for worst-case attacks that compromise wider credentials.

4. How often should backup restore testing happen?

Monthly, using a full folder restore, not just a single file check.

5. What is the fastest way to know if our current backup is weak?

Ask when the last full restore test happened. If nobody has a clear answer, it has not been tested.
