Since MS Windows 2012 is supported with Data Protector, the disk agent is able to backup and restore files from deduplicated volumes. However, when the deduplicated volume is mounted into NTFS folder, the disk agent cannot recognize the deduplicated volume and hence, cannot backup the Chunk Store. No error messages is displayed during backup. The error appears when you try to open recoverd files. An error message from Windows about corrupted files is displayed and in no way it will be possible to repair these corrupted files. The error has not been seen when the volume is mounted as a drive letter. All versions of Data Protector supporting Windows 2012 and Windows 2012 R2 are affected. A hotfix should already exist and can be requested when a support case is opened.<\/p>\n","protected":false},"excerpt":{"rendered":"
