Are subsequent backups to iTunes incremental?

Apparently, subsequent iCloud backups are incremental. Just wondering if subsequent backups to iTunes are the same? Or does it do full backups every time?

I'd also like to know. Does anyone have an answer?

No, they are full back-ups.

Edit:
Actually, not 100% sure anymore. On my iCloud back-ups, it has been saying 58MB as the latest back-up size (it backs-up everyday & I haven't changed/added anything in my iPhone in the past 3 days) - so it appears it isn't incremental but I don't have definitive proof.

Found out for myself. Subsequent backups (for each iOS version) are incremental. First backup to iTunes took a while, but the subsequent one took seconds. It's the same for both USB or WiFi backup.
