RegBack Notes

RegBack and RegRest save and reload the entire registry hive, including access control lists. So it's possible to restore a hive and find that you have different ACLs than before.
RegBack does not automatically back up files that are not in the CONFIG folder, such as user profiles. However, you can back up these files manually. This avoids name conflicts.
RegBack does not copy the files in the CONFIG folder that are not currently kept open by the registry. Use Xcopy.exe or Scopy.exe to save inactive hives.
RegBack only backs up active hives. For hives that are not loaded, you can just copy the files.
RegBack will stop at the first bug, except for manual hives.
RegBack will not overwrite existing files; instead, it reports an error.
RegBack fails if the hive files don't all fit on the target, so often it's best to use RegBack to back up hives to a hard disk folder and then use Backup.exe, or use Xcopy.exe or Scopy.exe to save the backed-up hives on floppy disks.
If you have a tape drive, use the Windows Backup program instead. Start Backup by double-clicking its icon in the Administrative Tools program group.
