Please consult the release notes:
https://www.firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-general.html

In general it is not necessary to backup and restore within the same
ODS, if it is necessary (or recommended), this is explicitly mentioned
in the release notes.

The only backup and restore that is recommended is if you created the
database in Firebird 2.5.1 (including restores to that version) and move
to 2.5.3 or higher. See:
https://www.firebirdsql.org/file/documentation/release_notes/html/en/2_5/notes-253.html
