If you mean binary backup, you can enable buildpkg in FEATURES and wait for next+1 updates, then you'll have binary package of current and previous version... If you just want to know what was previously installed, but don't mind recompiling, you can use the "demerge" package, which saves state and allows you to revert to a previous state (emerge back to exact package versions that were installed at a certain date and time). It can also use binary packages if they are available (when used alongside buildpkg for example). There are also commands to create binpkg of an already-installed package, if you have specific times you want this but not all of the time.
