The Windows Home Server team has solved a software bug that may affect files that are compressed using Advanced Attributes (NTFS compression). NTFS compression can be enabled on an individual file, folder or at the hard drive level and is sometimes enabled by users to save disk space on a home computer. More information on the bug and a link to download the fix at KB950190.
On a home computer, you can compress some files by using NTFS compression through advanced attributes settings. In some cases, these files may not be backed up correctly by Windows Home Server. If you try to restore a compressed file from a Windows Home Server backup, the file may be corrupted.
The update is for the Windows Home Server Connector, and will need to be installed on each of your home computers. Given that your previous backups may be damaged by this bug, it’s worth running an immediate Manual Backup as soon as the fix is installed on each of your home computers.
