According to our Support Team, this error is due to inconsistencies in the backup file. Here are a couple of troubleshooting tips to help you with failed 23(data error (cyclic redundancy check).)(microsoft.sqlserver.smo).

We can check if the backup is in a consistent state by running RESTORE VERIFYONLY on the backup file. If not, our Support Engineers suggest running a checkdb on the source database. If the CHECKDB output is clean, try taking a backup and restoring it once more.

Another way to resolve this issue is to go ahead with a quick health check on the disk where the backup files are. If the results do not come back clean, we have to check the level of corruption.

If the errors cannot be repaired, we have to perform a point-in-time recovery of the source database. Rather than running REPAIR ALLOW DATA LOSS, drop a line in the chatbox to talk to one of our skilled Engineers and resolve the issue.
