A GRAMPS 3 database (and any .grdb file) is very dependent on the software versions that created it. For example, you can't just move your GRAMPS data in these formats to a different operating system (or even a different version of an operating system) and expect that you will be able to read your data. The data is not "portable". Therefore, you can't just rely on backups of these formats, but you should also occasionally export into a format that is portable. There are two possible portable formats: GEDCOM and GRAMPS XML (.gramps or .gpkg). But only GRAMPS XML is recommended, as it faithfully saves all of your data.
