|Message:||<process name> (<process id>) <storage group name>The backup database <name> must be a multiple of 4 KB.|
The corruption of data may have occurred during the backup or restore process, causing the database file to be truncated to a size that is not a multiple of the size of this unit.
Try the restore process again. If the problem persists, then this backup may be corrupted and an earlier backup should be used.
