Delta Drive, Delta Trust & My Drive · Delta Trust backups
Does Delta Trust protect my backups from ransomware?
Short answer: Yes. Once backed up to Delta Trust, nothing on your Mac — no program, no intruder, not even us — can delete or overwrite it for a set number of days, so ransomware can't destroy your backup history.
Yes — that's what it's built for. Once something is backed up to Delta Trust, nothing on your Mac can delete or overwrite it for a set number of days: not a program, not someone who has taken over your Mac, and not us. The protection can't be waived by whoever is holding the keyboard, which is exactly what makes it safe from ransomware.
If your Mac is compromised, your backup history from before the attack is still there to restore from during the protected period. The Copies screen shows how many days your main copy is locked for.
