I have an old FB1.5 database working from 2005 until today. It has a little more than 700 MB. Works on Windows 7 Professional...

Finally, I decided to update to new server etc. Simply, I thought - gbak backup on FB1.5 and restore to FB3...

But (works fine in app - Delphi app with IBX etc.) when trying to make GBAK (FB1.5 gbak) the procedure just stops and I get cca. 200MB .fbk file...

When I try to restore, it asks for next volume... so, I suppose backup failed. (When looking gbak with -v it works fine and finally gets to certain table, says something like:

gbak: 160000 records written

gbak: 180000 records written

gbak: 200000 records written

gbak: 220000 records written

gbak: 240000 records written

gbak: 260000 records written

gbak: 280000 records wri

...and brings me back to my terminal, without any failure notice.

So, I'm stuck. I don't know what to do, how to create proper backup or at least find the reason of such a behaviour. Again, app works fine and doesn't give any issues when working with DB.
