Which of the following is a safety feature of cloud-based backups?

An incremental copy of data is a method of backing up (saving only changes), not specifically a safety feature unique to cloud or a primary safety mechanism against disasters.

A local copy of data refers to storing backups on-premises, which is the opposite of a primary safety advantage of cloud-based backups.

Offsite storage of data is a major safety feature of cloud-based backups. By storing data in a remote data center, it protects against localized disasters (e.g., fire, flood, theft) that could destroy both the primary data and any local backups, thus enhancing data resilience and availability.

A full backup of PC data is a type of backup (copying all selected data), not specifically a safety feature in itself, though it contributes to comprehensive data recovery.
