It is 24 hours. The only reason I know is because I just subscribed to plus today for the cloud feature so I could transfer my game saves to my new slim that I just traded in my phat for. The only way to move copy protected files is with the cloud feature or the transfer utility, not the backup/restore utility. Since I traded my old console in, I couldn't do the transfer.
Anyway, long story short, you have to wait 24 hours to download/upload each time.
