The original bug was caused by myself, by being so stupid to forget that files have sizelimits, but hey, it was though out and implemented in about 30 minutes. The backup-utility however shouldn't have this limit, as it is transferring and writing multiple small files to disk. I know of some problems with displayserver and playlists, but files should download correctly. Maybe a FAT/FAT32 limit on the number of directory entries?
BTW have you got the player running while backing up? When you stop the player app, you will notice an increase in speed of about 100%, at least that's my experience(250kbs/500kbs).
I haven't downloaded that amount myself; I stopped at 2 Gb.
I will try to make a full backup soon, and let you know...
