What is data error?ĭata errors are errors that occur while processing the data. Why is it called Cyclic Redundancy Check?ĬRCs are so called because the check (data verification) value is a redundancy (it expands the message without adding information) and the algorithm is based on cyclic codes. If CRC errors occur, the following is suggested, but not limited to: Verify that the compression and name space options are set the same as they where when the backup occurred. In short, a CRC check failure indicates that the information on tape is not identical to the data on the hard disk. Typically this means the file is corrupted or didn’t download correctly, so I would try downloading or copying the file again.
