Incremental is the fastest backup strategy. After a full backup, only changes from the last backup are backed up each day. This differs from differential backup where all changes since the last full backup are recorded each time. A snapshot is a “shot in time” of a file system that when used to restore that file system restores it to that exact moment. This isn’t technically a backup strategy due to the fact that the snapshot is stored in the same location as the original file.
