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. Differential Backup Differential backup contains all files that have changed since the last FULL backup. That is where it gets its name: it backs up everything that's different since the last full backup. The differential backup is like the incremental backup type but does not clear the archive bit as incremental does. 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. Incremental Backup Incremental backup stores all files that have changed since the last FULL, DIFFERENTIAL OR INCREMENTAL 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. Copy Backup Copy backup is the same as a Full backup except the Archive bit is not cleared. This prevents this particular type of backup job from impacting any other scheduled backup jobs, preventing changed files from being skipped by scheduled differential or incremental backup jobs that are matched to a full backup. Daily Backup Backups only files that were created or modified on the current day.
