First of all go to the FAQ at
www.e-smith.com and read what files are included in a backup and what files are restored.
If you are using backup to desktop not all files are backed up.
If you are using tape backup all files are backed up but only some are restored. You need to use flexbackup at the command line and manually restore the other files. Search the forums for how to do this.
Generally you need to reinstal any add on rpms, after doing a restore to a freshly installed OS (which is the recommended method).
