Problem with Backup?

Hello all, i am trying to do a buckup, but this message is shown, can anyone to give me any way haw to fix this problem? Thnx in advance for all.

Read the following link:

That error is quite common, but there is no clear solution (I think).

I’m having this error when I try to do navision backup from sql database. But navision backup works fine with the same copy of db in native.

So, is there any difference between navision backing up from native and sql?

If the data was corrupted so then the error should happen in both cases. Am I right?
