Hi,
Usually when nbackup fails you cannot merge delta file with main database. Sometimes database continue to work (and delta file grows), sometimes you cannot connect to database.
In this case you need to contact IBSurgeon support for recovery - we have tools to fix it.
It's pretty rare situation, more often you can notice that database is corrupted, while nbackup is working normally - it's working on page level and record-level corruptions are out of nbackup scope.
To avoid such situation, make usual backup (with gbak) and test restore regularly.

I hope you are not fed up with my nbackup questions :)
I didn't have any nbackup problems other than being slow on the first full backup process but as I write in the subject line, what happens if nbackup fails while taking a full backup, for example if disk space runs out? Can you think of any potential problems if nbackup fails unexpectedly while backing up?
