Failed Status - V-79-57344-4611

We are experiencing an issue with our VMWare backups writing to the deduplication storage. Other file level backups complete to the same deduplication storage without issue. Some files and folders were copied from another drive to the deduplication drive when the other drive was full. Those files and folders have since been moved but the VM backups continue to fail. I have ensured that the virus software is not scanning the deduplication drive and that indexing is turned off. Any other ideals on how to resolve this issue while maintaining the current backups on the deduplication drive?
