a backup that only contains the files that have changed since the most recent backup (either full or incremental). The advantage of this is quicker backup times, as only changed files need to be saved. The disadvantage is longer recovery times, as the latest full backup, and all incremental backups up to the date of data loss need to be restored.
A synthetic backup is an alternative method of creating full backups. Instead of reading and backing up data directly from the disk, it will synthesize the data from the previous full backup (either a regular full backup for the first backup, or the previous synthetic full backup) and the periodic incremental backups.
A differential backup is a type of data backup that preserves data, saving only the difference in the data since the last full backup.The rationale in this is that, since changes to data are generally few compared to the entire amount of data in the data repository, the amount of time required to complete the backup will be smaller than if a full backup was performed every time that the ...
A reverse incremental backup method starts with a non-image full backup. After the full backup is performed, the system periodically synchronizes the full backup with the live copy, while storing the data necessary to reconstruct older versions. This can either be done using hard links—as Apple Time Machine does, or using binary diffs.

Backup solutions generally support differential backups and incremental backups in addition to full backups, so only material that is newer or changed compared to the backed up data is actually backed up. The effect of these is to increase significantly the speed of the backup process over slow networks while decreasing space requirements.
Macrium Reflect can create full, incremental and differential backup images, or selectively back up individual files and folders. Data is compressed and encrypted in real time using LZ-based compression and AES encryption algorithms.
Backup types Areca could handle the following types of backups: Full Backup: When a full backup is performed, ALL files are stored in your archive (whether they have been modified or not). Incremental backup : When an incremental backup is performed, only the files which have been modified since the last backup are stored in your archive.
