The backitup-rus.nls file is a language component of Nero BackItUp from Nero AG.  Nero BackItUp is a backup program that burns your files to DVD’s and CD’s either automatically on a schedule you set up or manually.  Files with an nls extension are National Language Services drivers, which set up fonts and character maps for each supported language.  This file supports Russian.

If the nls files for a program are not properly installed, the program may not run, or it may only have problems when you attempt to run it in a language that should have an nls file.  An error with an nls file should be checked by running a registry cleaner.

Your Windows registry is an information booth for your operating system.  It tells Windows where to find the files to run your programs and what to do to make those files work.  Registry cleaners check every one of the thousands of entries in your registry for errors, and fix those errors.
