That's because of the size of the database files (typically MDF and LDF).

The backup size will be around the same size as the used portion of the MDF file, so yours is probably around 2GB used space inside the MDF. You might have a 100GB file (just as an example) configured for the MDF file, so it needs to create that same file during the restore.
