using Root Explorer for example (or by using adb). Just add .bak to these file names.
Updating and keeping root requires using OTA RootKeeper to back up su, installing the update, and then restoring su.
Note that once updated to 4.5.629 you won't be able to go back to a fully functional 4.5.608 (or anything prior to that). You still can SBF and even regain root after that, though.
