Unable to recover files with special file names

Thread needs solution

After backing up 4 files from a NTFS volume in a single full file backup, I am only able to recover 2 of them. It seems to be related to their file names. The 2 files seem to be somehow blocking the recovery of the other 2.

The name of the files are:
CAROLI~2.BK!
CAROLI~2.WPD
CAROLI~3WPD.BK!
CAROLI~3WPD.wpd

I have attached these files in a zip file. Also I have attached some screenshot that shows

  • All 4 files have be chosen for recovery
  • The result of the recovery is "Succeeded"
  • Only 2 files have been recovered

I have created the 4 files myself in Windows 7. They only contain a few characters I have typed in notepad. There is nothing special about them except for their file names.

I am aware that it is some strange file names. But if Windows 7 is able to manage them without problems, I expect Acronis Backup to be able to back them up and recover them also.

Hi René,

Have just tried to Backup and Recover your attached data-files. All 4 files have been recovered to the original location (renamed the original ones).

I had used AB11.7 (Build 44421) on a Windows Server 2102 R2 Machine.

Hi Raphael

Thank you for your help. I have tried to delete the original files and recover to the original location. Only 2 files are recovered. I have tried to disable the virus scanner. Same result, only 2 files recovered.

I am using Acronis Backup 11.7 build 11.7.44421, which seems to be excatly the same version you are using.

My Windows 7 installation has not been updated for a while. I will try to wipe the whole SSD drive, reinstall Windows 7, install all updates from Microsoft, install AB 11.7 and retry the backup + recover preocedure on the 4 files.

 

Here is a bit more information about what I am doing. I am in the process of evaluating if Acronis Backup has the needed quality for me to trust it and use it for backup. I have been making a backup of about one million files at a total size on about 2 TB from one USB hard drive. Then I have been recovering the one million files to another USB hard drive. After that I have used another software tool to verify that the recovered files were identical to the original. All one million files were exactly identical on bit-level, except for two files that were completely missing. They had the names that I mentioned in my first post. After that I reproduced the problem with 4 files that I have created myself using notepad. The problem were reproduced on an internal SSD drive, both the backup and recovery part.

 

Hi René,

I have tried to recover the data-files in Windows 7 SP1 (64-bit, Patches up to April this year), but all 4 files are recovered correctly. This test-recovery machine is a VMware-VM, will try this on my notebook where a SSD drive is installed.

Can you see any difference in the target directory where the data-files reside?
In my recovery tests the files were backed up and recovered from/to the current users Documents folder.

Ok, have tried some options in recovery and finally I can reproduce it and two of 4 files are missing.

Missing files:
CAROLI~3WPD.BK!
CAROLI~3WPD.wpd

It looks like it happens only when the files are recovered to a different location than its original.

Reproduceable in Windows 7 and Windows Server 2012 R2. When recovering the files from a AB11.7 created archive using AB12 to recover, the two files are missing after recovery, also.

I suggest to open a Support Request, you should refer to this thread in the request.

Thanks!

That is great news. I have been stuck trying to reinstall Windows 7 from an original Microsoft DVD. I think I have tried to do that 5 times now. Windows 7 installs perfectly but every time I try to update it using Windows update it keeps searching for new updates forever(hours, before I give up). I have installed Windows 7 many times from original DVD before but never tried anything remotely like this. The internet connection works fine and the installation is activated with no problems.

I am so happy to hear you can reproduce the problem and thank you for your great effort. The problem with opening a support request is that I acquired the software a few years back for another purpose than regular backup. I have not had a need to use it for regular backup before now. My support program expired April 09, 2014, so I cannot open a support request. I was hoping someone from Acronis would read this forum.

Hello René

We will look into this sitaution and I will post back here.

Thank you.

Hello,

We reproduced the issue. The internal code is ABR-113030. I don't have any details on why this happens, but I will update you as soon as I have more news from our developers.

Thank you.

Hello Everyone,

Just in case, we have figured out that this happens because of a coincidence in the naming pattern for these files and the pattern in some temporary files we create during restoration. There is a name collision that isn't resolved properly due to the symbols and incrementing number.

Thanks for Info!

This will be fixed in futures releases?

Hello,

Yes, definitely. We are targeting the next release, but I can't promise anything specific because I don't know the details of the complexity of this fix.
