CRC test fails on multiple files

Post by lyrebird23 »


I'm running a backup on a large number of pdf, word and excel files, and the results show 0 errors but there are warnings for about two thirds of the files.

The warnings all say the same thing:
'Warning: CRC test failed for file "<filename>". CRC stored in catalog is 0, destination CRC is 0'

I've tried running the back up several times but always get this error.
Can anybody give me some ideas of what is causing this and how I might fix the problem please?
