system32\config\regback fills up

I've had my Vista computer for about 14 months. Gradually my hard disk has
filled up. I've traced this to the system32\config\regback directory, which
now contains 32GB of files mostly named REGxxxx where xxxx is a sequence
number.

I understand these are registry backups of some sort. What is safe to delete?

There are several backups for each date I've owned the computer, with some
days missing. Why doesn't Vista automatically get rid of old backups instead
of filling my hard disk?
 
Hi,

Basically, there should be two backups of each of the five registry hives
named <hive> and <hive>.old as well as the associated logs. For instance you
should see:

SAM
SAM.OLD
SAM.LOG1
SAM.LOG2

Anything else for each of them can be deleted.

Thank you for the response, Rick. I see the two backups of each of the five
registries as you describe.

But there are also a gazillion files named REGxxxx. What are these? If I
don't need them, can I stop them from being created?

Thanks,
Howard
 
I use Norton Internet Security for system protection. Don't know how to tell
if NIS is creating these files, or how to tell it to stop if it is.

Thanks.
 
I stumbled across the answer. See:

In short, they are temporary files used by ntbackup. (Since Vista doesn't
come with a reasonable backup program, I've been using ntbackup from XP).

It's a program bug in ntbackup - the temp files should be deleted.
Apparently it's safe for me to delete them.

I do not understand why I'm having the problem as the app note says this
applies to network backups, which I'm not doing, but I'm happy to have an
answer anyway.

Well, I guess that's informative. But obviously not much help - just like
my question, I guess :-)

I was kind of hoping that they might be REG0001.reg or something that would
provide a clue.

There are no files named like that on my computer (or else I searched
wrong), and nothing like that, without a filename extension, on Google (or
else I searched wrong again...).
 
Thanks for the update.

Who knew? :-)
