Yes, it is, but you must keep in mind that restoring an older db can break db/file system synchronization. If a title or an author was changed between the backup and the restore, then the file system will reflect the new data but the db will reflect the old. Calibre will be unable to find the formats or covers for books in this state.

You can use check library to find these problems. In most cases (all that I can think of), you can recover by renaming the 'extra authors/titles' to what calibre wants them to be, which will be shown in 'missing authors/titles'.
