Right. You must have created this database using a Firebird 2.0
beta. The , which is what the gbak error is telling you that the
on-disk structure of the backed-up database is ODS 11. Firebird
1.5.x creates ODS 10 databases and recognises ODS 10.n and lower.

Historically, you simply can't restore a backup of a higher ODS
database to "revert" its ODS to a lower one. However, you *can* do
as follows with Firebird 2.0 and 1.5.x specifically:

1. Temporarily rename gbak.exe in your Firebird 2.0 bin directory.
2. Copy gbak.exe from your Firebird 1.5 bin directory into your
Firebird 2.0 directory.
3. With Firebird 2.0 as your running server, use this Fb 1.5 gbak to
back up your database.

You now have a backup file that you can port to a running Fb 1.5.3
server and restore. However, you will encounter further problems if
you used any new DDL features in creating objects whilst your
database was under Fb 2.0 control.

NB, don't forget to reinstate the proper status quo for your binaries
in Fb 2.0 if you plan to keep using Fb 2.0.
