There IS a Backup Tool in jv16PT ... always was.
Exists also for Registry Compactor: Full registry backups (files with extension ".bak_jv16pt") of the compacted root hives are stored in the same directories as the original root hive storage files (i.e. normally "C:\Windows\System32\Config").
The option to do a full backup and restore was already asked to jv16 and he promised to include it later.
