Yes and no and yes... It stores *changes* to the file systems, so how much space it needs depends on how full your file systems are, how often and how much you write to them, etc. Also, at every recovery point, you can discard all but the last change since the previous recovery point for every changed block. FWIW, the exact same answer applies to pretty much any backup solution that supports incremental backups.
