Gbak backup makes a copy of the current version of all data in its backup
file. Gbak
restore creates a new database and populates it with that data. Records
all get new
home pages.

You have little or no control over that. Yes, Firebird tries to keep all
versions of
a record on the same page, but there's almost nothing, other than reserving
on pages, that you can control to influence the location of record versions.

Good luck,
