Windows Server Backup - ASR Writer failure RRS feed

  • Question

  • Hi,

    I have been trying to resolve this problem for a while now.  I replaced the main HDD on my server, (by using a drive clone) and ever since then the BMR portion of my daily backups fails with this error:

    "BMR backup failed as ASR writer failed while creating shadow copy and was skipped. Detailed error: The writer experienced a transient error.."

    I recall reading somewhere this had to do with an invalid volume name that the ASR writer can't handle, but I can't for the life of me find out how to find what and resolve it.

    Does anyone have any experience with this?

    Thanks,

  • I found another person with the same issue here:

    https://answers.microsoft.com/en-us/windows/forum/windows8_1-update/system-image-backup-consistently-fails-vss-asr/58479c8d-d171-47d3-b3ad-9faa8a97153a?auth=1

    They used Gdisk to solve their problem, and I also worked for me.  My GPT system, EFI and data partitions had invalid names "                    ...", which the ASR writer couldn't handle.  

    Copy Gdisk to your windows or system32 directory and use these commands

    gdisk32 \\.\PhysicalDrive??
    - where ?? is the number of the drive with the invalid GptName. Use DISKPART or Disk Management to find it.

    use 'b' to back up your GPT Partition data (I didn't)

    use 'p' to print the partition table

    - this is where I could see the invalid name

    use 'c' to change each partition's name. 

    use 'w' to write changes to disk and exit

    run backup again and see if it worked

  • Hi,

    May I ask what the OS for your server? You use windows server backup feature (WSB), right?

    When you run vssadmin list writers, what shows?

    Please also check the event viewer about application logs , any more message?

    According to your description, after replacing the disk, you get the error.

    Please check the drive,  if there's  invalid character about the volume?

    1. Launch the System configuration utility (MSINFO32)

    2. Navigate to Msinfo32-->Components-->Storage-->Drives

    When  there was some problem with disk information (Meta Data), it  will collect by ASR writers. Then will show such error.

    Best Regards,

    Mary

    I don't think this is the issue, as the event viewer shows the following.  How do the find the invalid character?

  • Hi,

    Based on the research, the error message indicates there was some problem with disk information (Meta Data) collected by ASR writer

    As suggested, you could check the drive:

    1. Launch the System configuration utility (MSINFO32)

    2. Navigate to Msinfo32-->Components-->Storage-->Drives

    Please checked with each and every volume information

    And for An invalid character, you could find like that:

    Drive P:
    Description Local Fixed Disk
    Compressed No
    File System NTFS
    Size 500.00 GB (536,867,762,176 bytes)
    Free Space 57.33 GB (61,553,922,048 bytes)
    Volume Name Vest&#x001f;CameraStorage  //-- Invalid Name
    Volume Serial Number C6E01C04

    In this example,  volume P: , “Volume Name” had invalid character in it.

    Best Regards,

    Mary

  • Hi,

    I checked MSINFO32, all the drives show valid volume names.  I think it is one of the system partitions that has an invalid name as it's only the BMR that fails, not the rest of the backup.

    It looks to me like the GptNames for the system partitions on C: are invalid, specifically partitions 1, 2, & 3. 

    Can I reset the names on those partitions?

  • I found another person with the same issue here:

    https://answers.microsoft.com/en-us/windows/forum/windows8_1-update/system-image-backup-consistently-fails-vss-asr/58479c8d-d171-47d3-b3ad-9faa8a97153a?auth=1

    They used Gdisk to solve their problem, and I also worked for me.  My GPT system, EFI and data partitions had invalid names "                    ...", which the ASR writer couldn't handle.  

    Copy Gdisk to your windows or system32 directory and use these commands

    gdisk32 \\.\PhysicalDrive??
    - where ?? is the number of the drive with the invalid GptName. Use DISKPART or Disk Management to find it.

    use 'b' to back up your GPT Partition data (I didn't)

    use 'p' to print the partition table

    - this is where I could see the invalid name

    use 'c' to change each partition's name. 

    use 'w' to write changes to disk and exit

    run backup again and see if it worked

  • After many hours of head banging, your post fixed my issues as well. Windows 2012 (r1), GPT Drive had the extended characters as well. Thank you!
