backup mode

Any of several modes for backing up, including Block, Agentless VMware, NDMP, Image, and File. One way in which the modes differ is the underlying method by which the data is transferred.

backup type

A term used to distinguish among base, incremental, and differential backups.

A full recovery using Bare Metal Recovery includes the operating system, point-in-time backed up data, and Oracle, SharePoint, SQL Server, and Exchange data if applicable. If the computer being recovered is a master server, Bare Metal Recovery additionally restores the application.

base backup

A backup type that backs up all the data in the selected job definition.
