BTW, that link you posted seems to assume that it's not possible to update a Full backup (at least, it makes no mention of the concept). Generally we can, except where the laws of physics conspire against us (for example, you can't update a single-Zip (one Zip, many files in it) over FTP, because the FTP protocol can't manipulate inside Zip archives). But you can update a compressed archive (single-Zip*) on a normal disk.
'Your' article seems to assume that's impossible, which ain't necessarily so. Some software might not be able to (some that use proprietary compressed backup formats, maybe), but generally we can. We don't use any archive format proprietary to our software (you don't even need to compress at all - just store the file copies 'raw' if you want, which is the default)
* but not if you also split the single-Zip into smaller chunks to fit CDs, etc, though. But you can't do that in Free anyway....
