Veeam Agent for Microsoft Windows (VAW) displays the following warning during the backup:
There are two scenarios under which this warning may occur: The disk of the machine being backed up has bad clusters, as recorded by the NTFS file system and reported to VAW, causing the warning message to be displayed. A backup of a disk that had bad clusters was restored to a new disk using VAW, and the bad cluster information from the old disk is being reported to VAW, causing the warning to be displayed.
Understanding How Bad Blocks Are Recorded The NTFS file system stores information about bad blocks in the $BadClus metadata file. More information about NTFS filesystem metadata can be found here. During a backup, if a block is not readable (i.e., corrupted), VAW will skip that block and disaply a warning message. Unreadable blocks on the disk may indicate that the disk is unhealthy, and replacement may be required. 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, a chkdsk must be run to force the NTFS filesystem to reassess all bad block locations.
