Re: NTBackup Hangs at Shadow Copy

Hi,

Glad to know you got it fixed. We backup folders separately so maybe that is
why.

Cheers,

The patch didn't solve the problem!

However, I deleted the DFS entries from the following registry folder and it
worked again. I read somewhere that too many entries in the
"FilesNotToBackup" Registry container can cause VSS to hang.

Reg key: -
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup

All working again now!

Sure,

Let me know if it works. I sure had a lot of problems with SP2 killing my
ISA server and pretty much everything else before I applied the patch on all
my servers.

Hey buddy,

Thanks so much for the reply.

I have run the Hotfix but will need to wait till tonight to restart the
Server and see if it has patched the hole.

In terms of Volume Shadow Copies, they seemed to work ok last time I tried
it but at the moment this is the main file server and I had Disk I/O issues
due to so many changes occuring on the file server (Part of a DFS-Replica
Set).

We are currently planning to install additional file servers for different
departments to reduce disk I/O loading.

Hi,

I had this with my Shadow Copy service as well as my NTBackup Service.

It got solved when I installed this patch (below) on ALL my servers.

Apparently SP2 creates a LOT of problems including this one.

Have you tried enabling Shadow Copies on the drives and seeing if you can or
if it errors out?

Hi there,

Tried your recommendations but it didn't work.

The errors displayed at the top of this help *** aren't related to my
problem.

I did hear that sometimes if the registry entry for "FilesNotToBackup" is
too full of entries then it can cause Shadow Copy problems in Backup. There
are a lot of entries in here because there are lots of DFS Shares hosted on
this server. Obviously I cant remove this entries because they are related to
the DFS Infrastructure and mean that the Backup doesn't backup all the DFS
config files in each share (as it should).

At the moment I can only backup the server from other R2 SP2 servers on the
network. But can't push backups from this server.

As i said, this server has the most DFS shares hosted on it, so perhaps
thats why, due to the Registry entry being full per the above paragraph.

Funnily enough I restarted this server (at midnight) a while ago, and it
solved the problem temporarily. Then it started again. God only knows why.

But having searched throughout the Internet, a lot of people are having
problems with NTBackup hanging on the "Preparing to Shadow Copy" section. No
solutions found yet though. A nasty bug that just had to bite me in the
backside on the main file server.

Having a real real nightmare with this now.

My backups just wont run on my Windows 2003 R2 SP2 server.

I go to create a normal backup using the wizard on NTBackup, then when I
set
it to run it just hangs on "Preparing Shadow Copy", hangs the NTBackup
app,
cranks the processor to 50% and thats it. I had a real issue the other day
when 5 backup schedules all did this during a day and ramped the processor
to
100% for hours.

I've tried searching the net for solutions to this but its hard due to the
nature of the error. Logs are empty in the backup logs, Event Viewer shows
the Backup "Begin" event then nothing. Scheduled task viewer hasn't had
errors in there for a while because I'm trying to solve the problem from
the
wizard not the sched tasks.

I just dont know what to do now. The Volume Shadow service seems to be the
culprit but I need Shadow Copy to backup open files. The service is set to
manual and stopped when i checked services. So i assume it just gets
called
for when backup time comes.

This is my main file server and with no backups going on - i'm worried as
you can imagine. My only other solution is to use NTBackup from the
Storage
server and pull data back but that seems to take longer than it did to
push
backups from the file server.

Any help is really appreciated - I'm in a dangerous situation at the
moment.

Cheers.

This might help:

If this was my own show then I would take one of the following
steps in order to remain covered until the problem is resolved:
a) Use robocopy.exe to perform a temporary backup over the
LAN to a machine with sufficient free disk space, or
b) Use robocopy.exe to back things up to a sufficiently large
external USB disk.
