There was a COM failure 0x80070005 - .\HoboCopy.cpp (169)

I understand that the failure code 0x80070005 apparently means access denied.
I have found a couple sites that I think might be pertinent:
http://www.tech-archive.net/Archive/Development/microsoft.public.win32.programmer.kernel/2007-09/msg00235.html
http://msdn.microsoft.com/en-us/library/aa387705.aspx

I am running Windows XP SP3.
Both "Volume Shadow Copy" and "MS Software Shadow Copy Provider" services have been manually turned on.
I run as a local administrator, but on a company domain and some security settings on my machine profile might have recently been changed.

Directory names have been changed to protect the innocent :)

Because I think regexes are a bad fit for the command line, I removed the /ignorepattern switch. Unfortunately, this is a breaking change, since at least one person is using it. I need to add something back in to support at least globbing, if not regexes, or else release hobocopy as 2.0.

It would be nice if hobocopy would support robocopy's /purge switch, since that would make copies a lot faster.

I have a script that I created to copy multiple directories to a backup location. The script needs to work with multiple src/dest pairs, which currently requires the hobocopy to be called multiple times, resulting in a VSS copy being made multiple times. It seems like it would be best if hobocopy had a mechanism for making one vss snapshot and multiple src/dest copies.

It's possible that making using of the backup privilege will help hobocopy succeed in scenarios where it usually fails. Need to do research into this, see if it will help, and add support for it. Open questions:

• Should it be an option or should we just always enable it if possible?
• If it's an option and we can't enable it, should we fail or try to proceed anyway?
• If it's an option, should it default to on and the switch turns it off or the other way around?

Here's a link to code that can enable the priv: http://msdn.microsoft.com/en-us/library/aa387705.aspx

Hi there,

I am using Hobocopy on a few computers and quite frankly it's a good piece
of software, it's simple, small and does a lot, and it's certainly on my
goodies list.

The problem is that it acts funny on some computers, and I wonder if you
could help me with this. Actually, it seems more of a VSC service problem,
but I figured since you wrote the code you should know a bit more about
Volume Shadow Copy than I currently do.

This is what happens on one of the PCs:

First issue, it seems not to be able to back up some MSSQL database files
and folders. I get something like this, with Verbose set to 4:

Component X is named XXXXXXXX, has a path of COMPUTER-NAME, and is not
selectable for backup. 0 files, 0 databases, 2 log files.

Also:

Component X has name XXXXXXXXXX, path COMPUTER NAME, is not selectable for
backup, and has parent (no parent).

Then, after a few dozen lines, it stalls at Calling DoSnapshotSet forever,
goes no further.

I have noticed that when requested to stop, manually, or via command or
batch file, the VSC service hangs in a "stopping" state, making it
impossible to be accessed until the computer is restarted.

I will be glad to provide more info if you can help me with this.

Thanks!

I would add a FAQ for the beginners like me regarding the creation of a initial statefile... I could suggest a text such as this:

!! FAQ
!!! How-to create a statefile

The statefile required to do an incremental copy is an xml file. The incremental copy will fail if you don't provide the name of an existing and valid xml file. It will also fail if you simply provide an empty file as this is not a valid xml file.

The easiest to get a valid statefile is therefore to run first a full copy of something (or even a copy of nothing by providing a filespec matching with none of the files in the source directory).
Ex.: hobocopy /statefile=myStateFile /full /y srcDrive:\srcPath destDrive:\destPath *.fake

Background

When running a backup with /skipdenied, the following error is encountered:

There was an error calling FindNextFile. Path: ... Error: 5 (Access denied)

and the backup terminates.

This is probably due to changes introduced in f8fc525.

Desired Behavior

When /skipdenied is specified, error 5 should not stop the backup, but should skip the files encountered.

Background

In this thread, a user reports that hobocopy fails to copy read-only folders as read-only.

Expected Behavior

A folder marked as read-only should be copied as such.

Status

Won't fix: people should use shadowspawn+robocopy to get more full-featured copying.

File name : [email protected]
The file name with two .(dot) is not transferred/copied.
The file is skipped in the transfer.

In W7 x64 using the Vista x64 .exe when I issue:
C:\Hobocopy>hobocopy /full /verbosity=3 /skipdenied /y /simulate "D:\Outlook\Phil" "D:\Phil\My Documents\Outlook Backup"
I get:
Starting a full copy from D:\Outlook\Phil" D:\Phil\My to C:\Hobocopy\Documents\O
utlook

Not exactly promising!

(I have found workarounds to convert to 8.3 names but I noted this issue cropped up a long time ago in the old blog.)

It is odd that the source directory name is not copied only its contents and if you want the source directory name, you need to explicitly put it as part of the destionation path. This may be the desired behavior in some situations but there should be at least a command line switch asking it create the name of the source directory at the destination.

example:

C:>hobocopy /full /skipdenied /y /r "c:\Program Files\Transparent" f:\temp3
HoboCopy (c) 2006 Wangdera Corporation. [email protected]

dir "c:\Program Files\Transparent"
Volume in drive C has no label.
Volume Serial Number is 6095-DF7D

Directory of c:\Program Files\Transparent

05/04/2008 01:51 PM

F:>dir temp3
Volume in drive F has no label.
Volume Serial Number is 5893-0797

Directory of F:\temp3

09/07/2008 11:07 AM

I would have guessed like cp or copy that instead there would be a directory under temp3 named transparent, which contained those files as a subdirectory. I understand this is not the way it was designed to work but there should at least be an option to do do this so you don't have to continually copy the dest directory in as your new dest directory for it to create.

Background

A user reported that hobocopy is never completing a copy. During the copy, it reports error 32, which is "The process cannot access the file because it is being used by another process." This really shouldn't happen.

The email thread is available at http://groups.google.com/group/hobocopy/browse_thread/thread/c94a81f117378175?hl=en_US#

Expected behavior

The copy should complete, and all files should be copied.

The error: "The application has failed to start because
the application configuration is incorrect.
Reinstalling the application may fix this problem."
when invoked from the desktop. When invoked from the
commandline (with and without arguments): "The system
cannot execute the specified program."

The machine:
Intel Celeron 1GHz w/ 384MB RAM
running Windows XP Home SP2
(Version 2002)--?

Package downloaded: hobocopy-0.6.0.0-xp-x32-release.zip
from SourceForge project page

Motivation

It's hard to beat robocopy when it comes to options and features. Hobocopy isn't even close. The one thing it can do better than robocopy is to copy in-use files. It would be great if there were a way to combine the strengths of the two.

Acceptance Criteria

• Hobocopy is able to create a snapshot and then launch robocopy using the snapshot as the source

Observed Behavior

From user Nick Massin:

I have noticed that (I can't remember off the top of my head which version) don't use the extension switch (ie: *.ext) properly and will not copy anything if the switch is present in the command.

Expected Behavior

• File globs should match properly.

hobocopy does not "see" filenames with @

Migrated from SourceForge: https://sourceforge.net/tracker/index.php?func=detail&aid=2046309&group_id=117783&atid=679446#

After the call to pBackupCompleteResults->QueryStatus(&hrBackupCompleteResults, NULL), there value of hrPrepareForBackupResults is checked instead of hrBackupCompleteResults.

Motivation

Sometimes it seems like hobocopy either spews too much information or too little. It would be nice if hobocopy would by default emit only the information that a user is likely to want to know.

Acceptance Criteria

• All current messages are reviewed to ensure that they are being emitted at the appropriate level.
• Any missing messages are added

h2. Steps to Reproduce

• Attempt to back up a directory named 'aux'
• Observe the following error:

Unable to determine if directory \\lorien\backup\ashendel\full-1\Work\relevance\ris-system\example-config\aux\ 
(as \\?\UNC\lorien\backup\ashendel\full-1\Work\relevance\ris-system\example-config\aux\) exists. Error was Access is denied.
 (Error number 5).

h2. Desired Behavior

• Directory is copied without error

h2. Open Questions

• Q: Is this really a problem with the directory name?
  ** A:
• Q: How is the program that created this folder in the first place doing it without error?
  ** A:

I am attempting to set up a script to run nightly backups from other servers to my backup server. I have created a backup script to run a full backup that has a few lines that look like this: hobocopy /full /skipdenied /y /r (Server Name)(Shared Folder) F:(Backup Folder)(Server Folder). When I run this command while testing I get the error There was a COM failure 0x80042308 - .\HoboCopy.cpp (351). I can copy files from my backup server to a network share but not the other way. I have checked to make sure the VSS and MSSCP services are set to manual on my backup server and other servers. Our old backup server uses robocopy and works correctly but when trying to rewrite the scripts using hobocopy syntax I run into this issue.

Background

When running hobocopy with the following command line:

/skipdenied /y /verbosity=3 /recursive /statefile=C:\data\backup\backup.state /clear C:\data \\avalon\backup\ashendel\full-0

The directory C:\data is not backed up. Rather, it appears to be attempting to copy all of C:.

Additional information: C:\data is a junction point, as are many of the directories on C:.

Expected Behavior

C:\data is the only directory that should be backed up.

Background

A user reports in this thread that hobocopy is behaving incorrectly when run with the /incremental switch. He reports that only the part of the file that has changed since the last backup is getting copied to the destination directory.

Expected Behavior

• An incremental copy should copy all of any files that have changed since the last copy.

Tech Notes

It looks like the issue might be that /incremental specifies that hobocopy make a snapshot specifying VSS_BT_INCREMENTAL, which I guess actually only shadows the portion of the file that has changed. We want VSS_BT_FULL, so that the whole file gets shadowed.

Currently, hobocopy always copies recursively. Provide a way to copy non-recursively. And clear up the /r switch, which doesn't seem necessary.

I have issue, please help me!

I noticed the flaw that hobocopy creates subdirectories when the target is a UNC network share. I've seen this on Windows XP and Windows 7 32bit, I did not test 64bit systems.

The command line

 x:\path\hobocopy.exe /statefile=\\server\share\a.state /verbosity=3 /full /skipdenied /recursive y:\dir\ \\server\share\backup\a\b\ *.pst

creates in the current working directory the subdirectories
server\share\backup\a\b
with no files in it. This also happens when all qualifiers are omitted.

Recent versions of robocopy allow copying of folder timestamps via the /dcopy switch. It would be nice if hobocopy offered this functionality as well.

And have a Verbosity option that shows the files copied.

Its just easier than a redirect and the listing shows what happened!

I have read your great article http://craigandera.blogspot.jp/2006_09_01_archive.html a few weeks ago and downloaded the source code.
I am trying to develop a program to backup my system. In my opinion, I would like to copy all the data sector by sector. Because my C drive contains a lots of file.
If copy the files recursively, it will take a very long long time.

Finally, I write a function CreateShadowCopy base on your codes. This function will create a shadow for me and returns a path
"?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1", I try to open the path "?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1" (without the final "") using CreateFile as a device.
In my program, it reads all the data sector by sector and write them to another partition.

But unfortunately, the cloned partition is corrupted and contains a lot of errors. Does it meas that VSS does not support coping data sector by sector?

Best wishes

It would be nice if you could specify to copy additional attributes, like robocopy:

  /COPY:copyflag[s] :: what to COPY (default is /COPY:DAT).
                       (copyflags : D=Data, A=Attributes, T=Timestamps).
                       (S=Security=NTFS ACLs, O=Owner info, U=aUditing info).

Please package Hobocopy as a library so I can use it in a C# program for example.

It would be nice if people didn't have to figure out if their machine was 32-bit, 64-bit, or what operating system they're running before downloading. Having a single executable that runs on any platform would make this easier.

Tech Notes

One way to implement this would be to package the various executables into a single wrapper exe that would detect the OS and bitness of the system, and then extract and run the appropriate exe, passing along the command line arguments. Even better if the exe included the CRT redistributable, detected if it were installed, and offered to install it.

Hello, I like your utility very much. Where does the snapshot taken during the execution go? I looked at the previous snapshots taken with the schedule on my w2k3 server and it's not listed? Can the latest snapshot taken by the shadow copy scheduler be used instead of making a new one during the Hobocopy run?

Background

It's a standard feature of command-line tools that abbreviated versions of switches be available. For example, "/r" as an alias for "/recursive". Hobocopy should support this convention.

Acceptance Criteria

• All command-line switches have a short-form equivalent.
• The documentation is updated to reflect this.
• A new release (point version change only) is published with these changes.

Since there is four different versions of hobocopy that current exsists, for each OS and stable versus unstable. It would be helpful if there was a command line switch for version. "/version" so that users could know which version they are on.

Additionally, it would be helpful if a check for the Visual C++ Runtime version could be performed to inform the user that they need to install that particular version of the build.

Background

Currently, when making a full copy, hobocopy simply records the time of the copy in statefile. When doing an incremental copy, the copy simply looks at each file, and copies it if it has been modified after the date in the statefile. That's not really right, though, as things like moving a directory or a file don't necessarily change the date, but should be reflected in the incremental copy somehow. The issue with this is that when a user restores the full backup and then the incremental one, they could wind up with two copies of some files. Worse, one of them will be old.

Expected Behavior

• Users should be able to reproduce the state of the backed-up directory using the full backup and an incremental one.

Open Questions

• What should we do about deleted files? Perhaps a list of deleted files should be produced. What do other backup tools do?

Hello Wangdera,
do you think it is possible to auto create the Statefile the fisrt time we launch Hobocopy in incremential mode ?

For the moment it don't works if the statefile is not present. So I use a script like the code below, but it might be preferable to implement it directly in the program.

Batch file :

@echo off
if not exist .\HobocopyState.xml goto FirstTime

:Incremental

echo +--------------------+
echo ¦ Incremental backup ¦
echo +--------------------+

hobocopy /statefile=.\HobocopyState.xml /skipdenied /incremental /r %1 %2 > %3
goto End

:FirstTime

echo +-------------------+
echo ¦ First time backup ¦

hobocopy /statefile=.\HobocopyState.xml /skipdenied /r %1 %2 > %3
