1. Full backup
Full backup is the starting point for all other backups, and contains all the data in the folders and files that are selected to be backed up. Because full backup stores all files and folders, frequent full backups result in faster and simpler restore operations. Remember that when you choose other backup types, restore jobs may take longer.
2. Cumulative-Incremental Backup
A differential backup contains all files that have changed since the last FULL backup. The advantage of a differential backup is that it shortens restore time compared to a full backup or an incremental backup. However, if you perform the differential backup too many times, the size of the differential backup might grow to be larger than the baseline full backup.
3. Differential-Incremental Backup
An incremental backup stores all files that have changed since the last FULL OR DIFFERENTIAL backup. The advantage of an incremental backup is that it takes the least time to complete. However, during a restore operation, each incremental backup must be processed, which could result in a lengthy restore job.
4. Synthetic Backups
A synthetic full backup is a backup assembled from a previous, non synthetic full backup, adn subsequent differential backups and/or a cummulative incremental backup. A client can then use the synthesized backup to restore files and directories in the sam wa that the clients restore from traditional backup.
