Diskeeper Undelete 2009 Server Edition is enterprise software for Windows Server 2003/2008 - it’s been around for a while, but at $499 a go it’s not exactly cheap. Rumour has it that Diskeeper is preparing a Windows Home Server version of Diskeeper Undelete with pricing around that of the current Undelete 2009 Pro product. The personal home use license is currently $59.95 (£57.07). The product may be available at the end of 2008.
Diskeeper Undelete2009 for Windows Server contains a whole suite of programs;
The Undelete 2009 Recovery Bin catches all files no matter how they were deleted, allowing you to restore them instantly with just a few clicks of the mouse. The Recovery Bin mimics the directory structure of your disk and includes a powerful search function, making it easy to find and recover files.
Undelete 2009 now automatically adjusts the size of the Recovery Bin to the available free space on a volume. If the size of a volume becomes critically low, Undelete automatically detects this low free space situation and reduces the Recovery Bin size. If more space is available, Undelete can protect additional files.
