CRC[=AUTODIN_II]
Uses the AUTODIN-II polynomial for the 32-bit cyclic redundancy
check (CRC) calculation and provides the most reliable
end-to-end error detection. This is the default for NRZ/PE
(800/1600 bits/inch) tape drives.
If you enter only Crc as the qualifier, RMU Backup assumes you
are specifying Crc=Autodin_II.
