The most widely error is shown when the NTBackup files are corrupted is CRC error. CRC stands for Cyclic Redundancy Check. A CRC is bit of mathematics used to ensure that your data is OK when being transfered. It's a checking procedure that quickly identifies when data has been damaged. If you get this message, it means that the file being read by your PC or software is corrupted.
However, it does not mean all the data is lost forever. When data is transfered, it is usually in small blocks and each block is given a CRC value. If something goes wrong with the data between the time it leaves the source and arrives at its destination, the CRC sent at the source will no longer match the one that is calculated when the data arrives - this is when the cyclic redundancy check error will appear.Due to this your NTbackup files get corrupt and you can not get back your data from NTBackup files.
