Hobocopy help?

[Zack, Joelle M.]

Hi Craig,

 

This is a very nice tool – I was hoping to use it to copy open .PST files.  Is that a valid use for this tool?

It looks like it creates the shadow copy, but it appears that the shadow-copy is still locked and hobocopy fails when it tries to put it in my c:\TESTCopy folder:

 

C:\Users\us041370\Downloads\HOBOCopy>hobocopy.exe "c:\users\us041370\my documents\outlook files" "c:\TESTCopy" archives2008-2010.pst

HoboCopy (c) 2006 Wangdera Corporation. hobo...@wangdera.com

 

Starting a full copy from c:\users\us041370\my documents\outlook files to c:\TESTCopy

Copy of file failed with error The process cannot access the file because another process has locked a portion of the file.

(Error number 33) on file \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\users\us041370\my documents\outlook files\Archives2008-2010.pst

 

Any suggestions?

 

Thanks so much!  --Jo

First, sorry for the delay in responding. I was out of town this last
weekend and am still catching up.

Indeed. That's pretty much the reason I wrote it.

Sigh. Well, you're definitely not the only person seeing this, or at
least a version of it. I'm slightly at a loss to explain it, but I'm
not giving up yet. If you can consistently reproduce this, that's
great, because I can't.

My employer gives us Fridays to work on open source projects, so what
I'll do is write a custom version of hobocopy then that can figure out
what has that file open. I'll launch handle.exe against the offending
file, which should tell us what has the file locked. Then we'll
proceed from there.

I've opened issue #35 to track this problem.
https://github.com/candera/hobocopy/issues/35

Thanks for the detailed error report!

Hi Craig,

Thanks so much for looking into this. I'll be happy to test the custom version and provide information back to you. Just so you know, yesterday I tried again (based on your comment that it is unpredictable) and it actually did work twice and failed twice. Still, I'm sure I can get it to fail for you.

I will be going on vacation next week, so I won't be back in the office until July 5 - I'll check back then.

Good timing - I was just about to send out an email. I've prepared a
branch build, available here [1]. It adds the "onlocked" option, which
lets you specify a command to run when hobocopy encounters error 32 or
33 when copying a file. I suggest downloading the excellent "handle"
program from Mark Russinovich [2]. Extract it into some directory (I
put mine in C:\bin), and run hobocopy something like this:

hobocopy /onlocked=C:\bin\handle.exe "c:\users\us041370\my

documents\outlook files" "c:\TESTCopy" archives2008-2010.pst

Then, if it chokes, it'll run handle against archives2008-2010.pst,
which should tell us what's got the file open. It'll appear along with
the rest of hobocopy's output.

Even if that tells us nothing, I still have a few more tricks up my sleeve.

No problem - I'd love to figure out what the heck is going on here,
but I only have a small amount of time to devote to hobocopy, so I
move pretty slowly anyway.

Sadly I can't get to the URL for the hobocopy files due to my company's internet filters.
I can download it tonight from home...
Thanks again, --Jo

I can also put it on github, if that would be better. Or on my google homepage.

[Craig Andera]

Wow - this is the first time that we've been able to get any useful
information on this bug! Thanks!

Now for the $1000 question: what the heck is plugin-container.exe? And
why is it accessing that file? And why, since it appears to be
accessing the file at C:\Users\, is it blocking access to the file in
the shadow copy?

Can you find plugin-container.exe anywhere on your hard drive? Maybe
the directory it's in will give us some clue as to what it does.

I realized that this statement is ungrateful to the people that spent
time helping me track it down before. I should have phrased it as,
"This is the first time we've had any luck finding the offending
process."

i tried to copy temp dir with internet explorer opened instead using
firefox, the result is the same.

strange, that worked time ago.

Sorry for the delay in responding.

So, I suspect this is due to a feature of VSS that lets the system
exclude certain things from getting backed up. This link [1] has more
information, but basically, if a file is listed in the registry under
HLKM\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup,
then VSS won't make a copy of it. On my machine, the whole directory
tree %TEMP% is excluded from shadow copies. So for me, anything under
C:\Users\candera\AppData\Local\Temp would be skipped.

The weird part is that I would think that would simply result in the
file not being found at all, rather than it complaining about the file
being in use. There is, however this article [2] that talks about the
registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsBackup

And some subkeys that might also have some influence. It's possible
that if a file is listed there, VSS does something weird like mount
the *actual* file in the shadow area, rather than a shadow copy of it.
In which case the file would indeed be in use by firefox or IE or
whatever.

So two questions:

1) What do you have under the two registry keys I referenced? Anything
that would cover the file/directory in question?
2) Does the file go away if you close Firefox or IE? If not, then the
easy way around this is to close the browser, then make your copy.

If the file *does* disappear when you close Firefox or IE, you could
also try using something like pskill [3] to kill the process instead
of closing. That might not give it a chance to clean up after itself,
and you could copy the file that way.

Let me know if any of that helps.

I think my answer to the other message in this thread applies to your
question as well. Let me know if the answer I gave there doesn't also
address your question and we'll deal with it separately.

> HLKM\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup,

i have a key called Temporary Files the value is %TEMP%\* /s

> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsBackup

this is empty

> 2) Does the file go away if you close Firefox or IE?

yes, also if I kill it with pskill

I'm using Windows 7

the weird thing is that I'm sure that I used hobocopy about 1 year ago
to copy those temp files but using windows XP. So tomorrow i will try
on xp (virtual machine)

[Craig Andera]

Bah! I can't believe I was rude enough to ignore this email for almost
two months. Sorry. Are you still having this problem?
