GDB files are not designed to be portable, nor to be backed up by
filesystem copy programs. GBK files (backups created by the GBAK program)
are highly portable.

What do you mean by "an IB agent"?

If a filesystem copy backup program is used whilst a database is running,
you risk corruption - there are very few ways you can corrupt a FB/IB
database and this is one of them. It's not just that the backed up file
will be inconsistent (because it will have changed before the copy is
complete) but Windows file-copying mechanisms actually lock sectors of the
disk during the copy, preventing the database engine from completing its
writes.

Moreover, if your customer is never using gbak, then there is important
periodic housecleaning that will never get done.

All that said, where does the error in the thread's title come in - "WRONG
PAGE TYPE IB6 ODS10" ? With IB 6 you can't open a database that was
created on a lower IB version...Firebird, however, will open, read from and
write to a 5.x database with a smile on its face.
