Every Sunday, your company creates a full backup. They make differential backups every day from Monday through Friday. They keep daily backup for a week, weekly backup for a month, and monthly backup for a year. What is the name of this backup scheme?

The grandfather-father-son (GFS) method of backing up makes sure that a system has short-, medium-, and long-term backups. You should have both on-site and off-site backups. According to the 3-2-1 backup rule, you should have three copies of your data on two different types of media, with one of those copies being off-site. A synthetic backup is a full backup that is generated by combining a recent full backup with the modifications made since then to create new files. Because it can be completed outside of the system, there is no downtime, and it is faster than a full backup.
