That's why I haven't activated cloud backup, although you can still make a manual iTunes backup after activating the cloud backup.
Well I just did this and it was not a FULL backup. Seems like it should be, but afterwards when I went into Movies in iTunes I didn't see my side-loaded videos, and the same goes for books, music, etc. I might have done something wrong, but I don't think so. The side loaded items are still on my iPod, they just didn't get backed up.
