Solved VSS is not working

March 8, 2013 at 08:26:23
Specs: Windows XP, Quad Q9450/4GB
I've been trying for days in vain to fix this problem on my XP PC.

VSS is not working properly. This wouldn't trouble me overmuch as I'm technically out of my comfort zone here. I don't really understand VSS, even after much reading. But my new backup program, SyncBackSE, apparently needs it in order to copy open or locked files. That's something which my regular program, SecondCopy, cannot do, so I want to fix it. And maybe there are other problems caused by this VSS failure.

I'm getting many Event Viewer entries of two types:
1. In the Application section:
'VSS Event ID 12289
Volume Shadow Copy Service error: Unexpected error DeviceIoControl(00000178,0x0053c020,00037CF0,0,00038CF8,4096,[0]). hr = 0x80070057.'

2. In the System section I get many like this:
' Volsnap Event ID 22
The diff area volume specified for shadow copies on volume C: could not be added.'

I would appreciate any help anyone can offer please.

What service pack do you have installed for XP?

FAQ: What are the system requirements?

http://www.2brightsparks.com/help/i...

SyncBackSE/Pro: Windows 2000 and earlier are not supported. The minimum version of Windows that can be used is Windows XP. Both 32-bit and 64-bit versions of Windows are supported. Note that if Windows XP is used then Service Pack 3 must be installed (if 32-bit Windows XP) or Service Pack 2 (if 64-bit Windows XP).

SP3. My PC seems to meet all the requirements - except, of course, that its VSS doesn't work!

It would help for the discussion here if I could share a simple test exercise that didn't rely on using SyncBackSE. My test so far has been to try backing up this folder used by Outlook 2002:
C:\Documents and Settings\Terry\Local Settings\Application Data\Microsoft\Outlook\.

It contains files like these:
archive.pst 4,896 KB
ContactsExtractbackup.pst 80 KB
Copy of mailbox.PAB 32 KB
etc

SyncBackSE hangs on encountering the .PST file, and I have to forcibly close the program.

Outlook is running during this test (minimised in XP system tray). If I close it then SysBackSE doesn't try to use VSS and the backup works OK.

I've also just tried a simpler test: backing up a folder containing a trivial .DOC file which is currently open in Word 2000. I expected VSS would get invoked for that, like the Outlook test. But apparently not, as the backup worked and there were no simultaneous Event Viewer errors.

--------------------


SyncBackSE Support recognise that many user have VSS problems. ("The Volume Shadow Copy Service (VSS) is notoriously easy to break but difficult to fix,") and have a page of recommended steps:
http://2brightsparks.com/bb/viewtop...

So far I've not succeeded.

Thanks, will study those. Seen quite a few of them from my research already, but maybe there's a magic bullet in the remainder!

The diff area volume specified for shadow copies on volume C: could not be added.'

Do you have enough free space to create the copy?

Thanks Paul, it was a small source folder and with about 40 GB of free space on the destination HD I don't think space can be the issue.

If there is no other solution, I would delete a few of the least necessary Restore Points and do a disk cleanup (CCleaner is good for both of these) and then try. I don't know what formula windows uses to apportion the MFT, but it might be worth a shot.

Have a look in Disk Management & see if you have System Reserved Partition.

You must have this, otherwise Windows Volume Shadow Copy Service (VSS) will fail.

Minimum size is 40mb, normal is 100mb.

John,

Thanks a bunch for that revelation. That really is new news!

Nowhere on the Syncback Support pages did I see that as a requirement and none of my hours of googling had turned it up. Where is it documented please?

That would certainly solve the mystery for me, because as you see I have no partitions. This 4 year old OEM PC came without any and in my impatience to transfer across all my stuff from a previous PC I foolishly didn't create any. Not that I would have even known about the need for a 'System Reserved Partition'.

I don't believe that is accurate. Many a Vista/Win7 install lack the SR partition. And virtually all XP installs lack it.

I think it was in the comments in this link Terry.

Maybe it was referring to a different operating system.

Hopefully it provokes a different approach to the problem, one clue leads to another.

Of course, there are plenty of Free programs that don't require VSS.

John,

Yes, it seems exclusive to Vista/Win 7 - and as Paul implies I think there's no consensus even there.

It's now academic anyway. I wouldn't have the confidence to attempt partioning my 750 GB OS HD.

Anyway, I've given up on VSS and had a prompt and cheerful refund of SyncbackSE. My SecondCopy does the job without using this obscure and complex VSS facility. My motivation was only to be able to backup locked files, like Outlook PST files, index.dat, Avira stuff, etc, but that's no big deal.

Because of curiosity and a dislike of seeing Event Viewer sprinkled with errors, I'd still like to see a solution to the mystery though, if not a fix!

If you want to test VSS without the program, open a CMD window and type:

net start vss

and then

net stop vss

In Vista/7/8 this may have to be an elevated window.

The problem is that a lot of programs, especially back up progs, use vss.
