Troubleshooting & messages · Delta Drive and Delta Trust messages
What does "Your history can't be destroyed for days, by anyone" mean?
Short answer: Each saved version is locked for the days shown, so no one — you, Storage Studio, or malware — can delete or overwrite it in that time.
Every version saved in your Delta Trust vault is locked for the number of days shown. During that time nobody can delete or overwrite it — not you, not Storage Studio, and not ransomware or anything else on your Mac.
That's the point of the vault: even if your Mac is compromised, your recent history survives.
