I'd suggest upgrading to 2.5.9 and see if that fixes the problem. Both in 2.5.8 and 2.5.9, bugs with gbak were fixed. Those bug fixes don't match the description of this problem, but it never hurts to try with a newer version. > I am facing some dificulties to backup and restore a corrupted DB.

However, did you read all the caveats about using -mend in the gfix documentation[1] as it can cause loss of data? However, did gfix output any information about problems? Preferably start with gfix -validate -full -no_update then move to gfix -validate -full and only use gfix -mend as a last resort (and make a copy of the database before running it!).
