Does Data Backup protect me from ransomware?

\n

Short answer: Partly. Versions let you restore files from before an attack, but backups on your own drive or account can still be deleted by anything with access. Delta Trust is built so nothing on your Mac can delete them.

\n

It helps, with an honest limit. Because Data Backup keeps earlier versions, files that get encrypted or damaged can be restored from a point in time before it happened. But a backup on your own drive or your own cloud account can still be deleted by anything that has access to it — including malware running as you.

\n

For backups that nothing on your Mac can delete or overwrite, there's Delta Trust, storage we run for that purpose. See Delta Trust questions. Keeping one backup offline — a drive you unplug — also helps.
