V-79-57344-34108 - An unexpected error occurred when cleaning up snapshot volumes. Confirm that all snapped volumes are correctly resynchronized with the original volumes.

 

Cause

This error occurs when Backup Exec attempts to back up a file affected by one of the following conditions:

  • The file is in use by another application or user. Backup Exec may back up partial data from such a file, but when it is not able to continue the backup of the file, Backup Exec marks the file on the tape as corrupt.
  • The file mentioned in the job log does not exist in the given location.
  • The file is being scanned by Anti-Virus software, or any other file protection or data replication process is occurring during the backup. This would include another backup running against the same resource at the same time as a problematic job.
  • More files are open than the memory cache manager can handle. As a result, the cache manager has exhausted the available paged pool memory. For details, please refer to http://support.microsoft.com/kb/304101
  • The backup program has tried to back up a file whose size is larger than the backup API can access on that version of the operating system. This has the same result (that is, the paged pool is exhausted).
    For details, please refer to http://support.microsoft.com/kb/304101

The error refers to the instance of the file on the tape or backup to disk file. The original file on the hard disk drive may be intact.

 

Solution

Use the Windows Event Viewer to check for any entries that occur around the time that backups are running or when you are performing tests on files and encountering errors. This may help to identify if there is a third party conflict, an actual file problem, or a software / selection list issue.
 
1. Enabling Snapshot technology can be used to avoid the error on certain types of open files. The Advanced Open File option of Backup Exec enables the functionality to perform a complete backup of files which are open through various applications.
 

2. If the jobs fail with or without AOFO, the following additional steps can be performed:

  • Raise the priority of the job
  • Create a new selection list for the backup job.
  • Run CHKDSK on the volume where the data resides.
  • Defragment the volume where the data resides.
  • Try taking a backup using NTBackup (Windows 2003) or Windows Server Backup (Windows 2008 and above) for the same file or volume.
    • If the Windows backup is successful, Backup Exec should be able to follow it with a successful backup.
    • If the Windows backup fails, Backup Exec will likely fail as well.
  • Check if VSS (Volume Shadow Copy) writers are in a stable state using the "vssadmin list writers" cmd.
    • Ensure the writers are not in any other state than "stable"
    • This error may arise if the VSS service is being restarted on the target server while the backup is in progress. Restarting VSS will delete the snapshot created at the start of the backup job and cause the failure. Make sure no other application is restarting the VSS service on the target server during the backup job in progress.
  • To increase the available paged pool memory on Windows 2003, configure PagedPoolSize and PoolUsageMaximum settings. For complete details on creating and configuring these registry keys, review Microsoft Knowledge Base Article below:
    https://support.microsoft.com/kb/304101
3. Deselecting  Advanced Open File Option is a better option for some jobs. If the job is failing even when AOFO is not used, try any of the following:
 
  • Ensure the respective files are closed during the backup.
  • Remove/Exclude non-existent files from a backup selection list.
  • If the file exists, verify that the file is accessible through the UNC path (i.e:  Start > Run > \\servername\filename) from the media server.
    • If the file is present and accessible at its location, try to copy the file from the target server to the media server
    • Verify that the file is not corrupt on disk, or being blocked by a firewall or protected by Anti-Virus or other software if there are errors
