If you backed it up with V2.1, you can't restore it with V1.5 gbak.
You might be able to restore it with a 1.5 server and the 2.1 gbak,
if the problem is that the V2.1 engine is fussier about checking
the validity of procedure references.

Gbak has a number of switches that allow it to restore quasi-invalid
backups. I'd try the -o switch which should get you your data.


Look on ibphoenix.com for the Backup Surgeon - there's a free one
that will tell you what is wrong and whether you need the paid version
to recover your database.


Good luck,
