anyone use novabackup?

i went to a client today who uses this and the full backup feature looks VERY similar to ifw in the opening screen where you select the type of backup and like paragon during the backup with the "capsule" etc.. any thoughts on this program it seems more of a file type backup but does do full backups as well. seems to similar to paragon in many ways...which made me curious what this thing really is. actually just realized the output files are .pbf so i am almost positive its really paragon
