Full Backup, Incremental and Differential Backup

Full backup, incremental backup, and differential backup are the most common three basic backup types. What’s the difference among these backup types?

1. Full Backup

A full backup is a complete backup for all data in the designated folders, files or drive, and represents the data at the time of backup completion, and it has the minimal time to restore data quickly. However, it will take a longer time to backup than other backup types and occupy a lot of storage space. And the most important thing is that the full backup is the baseline for any other backups, like incremental, differential, synthetic full backup, etc., which means you have to create a full backup before creating an incremental or differential backup.

Full Backup

2. Incremental Backup

Incremental backup will only backup files that have been created or modified since the last backup (full, differential or incremental backup). The restore process will need the last full backup and all the incremental backups for a full recovery.

Incremental Backup

3. Differential Backup

Differential backup will backup all the created or changed files since the last full backup, and it does not copy all of the data every time. You will need the last full backup and the latest differential backup to create a full restoration. That means you could not restore differential backup without a full backup.

Differential Backup

4. Synthetic Full Backup

Besides, there are some other backup types, like synthetic full backup (assemble a full backup with subsequent incremental backups), mirroring, etc.

Synthetic Full Backup

All the mentioned backup types usually used in SQL Server database, Exchange 2013/2016/2019, home and work environment, etc.

Tips: Full backup stores all files and folders, frequent full backups result in faster and simpler restore operations. When you choose other backup types, the restore process may take longer.
