We (as the nbackup developers) are not aware of any corruptions which
are the result of using nbackup from the FB v2.0 release.

We are very eager to work with you to clarify some details of your
corruptions and receive a copy/image of a corrupted database.

Please contact me directly, as soon as possible.
