A self-sufficient backup containing all data chosen for backup. You do not need access to any other backup to recover the data from a full backup.
A backup that stores changes to the data against the latest backup. You need access to other backups to recover data from an incremental backup.
A differential backup stores changes to the data against the latest full backup. You need access to the corresponding full backup to recover the data from a differential backup.
Single-file backup format (always incremental backup)
A new backup format, in which the initial full and subsequent incremental backups are saved to a single .tib file, instead of a chain of files. This format leverages the speed of the incremental backup method, while avoiding its main disadvantage–difficult deletion of outdated backups. The software marks the blocks used by outdated backups as "free" and writes new backups to these blocks. This results in extremely fast cleanup, with minimal resource consumption.
