BRU provides three types of archive verification. The first (-i, inspect mode) reads the entire archive to ensure that the data and the internal storage structures are intact. The second (-d, differences mode) reads each file in the archive and compares it with the corresponding file on the disk. The third, default, method is called AUTOSCAN and is performed automatically. BRU also provides a way to list the contents of an archive without performing any verification (-t, table of contents mode).
BRU’s -g option allows you to read the archive information block. This block contains the archive label and other information about the archive.
