Which of the following backup restore methods takes the LONGEST?

"Progressive" is not a standard, widely recognized backup method in the context of common backup strategies like full, differential, or incremental.

Restoring a differential backup is generally faster than incremental because it only requires the last full backup and the latest differential backup, not a chain of many small backups.

Restoring a full backup is generally very fast because all data is contained within a single backup set, requiring no other backup files to reconstruct the data.

Restoring an incremental backup typically takes the longest because it requires restoring the last full backup followed by every subsequent incremental backup, applied in the correct chronological order. Each incremental backup represents only the changes since the previous backup, necessitating a sequential reconstruction of the data state.
