Cyclic redundancy check (CRC)
Cyclic redundancy checking (CRC) is an enhanced checksum function. When this option is
selected, CRC checksums are written to the media during backup. CRC checks allow you to verify
the media after the backup. Data Protector re-calculates the CRC during a restore and compares it
to the CRC on the medium. It is also used while verifying and copying the media. This option can
be specified for backup, object copy, and object consolidation operations. The default value is
OFF.
Figure 49 shows the default configuration parameters for Ultrium tape drives. CRC checking was
OFF.
