One or more bad blocks were detected and skipped
During a backup using Veeam Agent for Microsoft Windows, each block is read. If a block is not readable (i.e., corrupted), Veeam Agent will skip that block and throw a warning message.
Unreadable blocks on the disk may indicate that the disk is unhealthy, and replacement may be required.
The NTFS file system stores information about bad blocks in a $BadClus
metadata file. More information about NTFS file system metadata can be found here.
Note: The $BadClus
metadata file is backed up by Veeam Agent for Microsoft Windows. If a bare-metal restore is performed to a new drive, the $BadClus
metadata is restored. To update the $BadClus
metadata file, run the command shown in the solution section of this article.
The following command will clear the list of bad clusters on the volume specified and rescans all allocated and free clusters for errors.
Execute this command on the machine that was being backed up. Specifying the volume for which the warning occurred (e.g., C: )
chkdsk [volume] /B
$BadClus
metadata file. Therefore if the warning persists after running the command above, there are bad clusters on the drive.Your feedback has been received and will be reviewed.
