It's been quite some time, if ever, that we've posted anything about Undelete. So, there's no time like the present. The next major Undelete release is in the works. While, as usual, I can't divulge some of the cool new things planned for that version there are a couple of obvious updates that will occur. One feature is adding x64 support and the other is support for Windows Vista. With Vista being a workstation OS, and the x64 platform more of a benefit to high powered application systems (video editing, databases servers, etc...), we actually haven't had all that much demand for these two functions. Most of our Undelete customers are buying the Server Edition for their file servers (where it captures network deletions). While it does well at what I call after-the-fact deletions, those are not its strengths. Undelete's real value is as a "file protection" product (prevents you from losing the file in the first place) and fits well into the Continuous Data Protection - for Files (known as CDP) category. Because I brought up Vista, I should mention the file system in Vista once again. In an earlier blog, while talking about Diskeeper, I noted that Vista's NTFS has no significant changes (just a few minor ones) to the structure with respect to defragmentation -which is true. However, Vista's NTFS has introduced major changes for file filter applications like Undelete. The new feature is called TxF, an acronym for Transactional File System. I'll write another blog on TxF, and cover its functionality and discuss some of the findings our developers and I have learned while investigating it.
