I found this: "Under Windows 7 RTM, I can use file copy to copy 250GB of files to my external eSata drive in about one hour at 72 MB/s.
When I try to use Windows Backup, it takes 14 hours to backup the same amount of data (i.e. about 5 MB/s). It looks like Windows 7 is trying to compress each file individually and is doing alot of Random Disk I/O. How can I speed up Windows 7 Windows Backup to get anywhere near approaching the 72 MB/s from a straight file copy? Are there any advanced options (e.g. in the Registry) that can be changed to improve this terrible performance? Having being forced by the OS to discontinue the previous use of reliable Tape backup via NTBackup, this is being to look like a conspiracy to force users to go and buy real Backup software from the likes of Semantec rather use the rapidly dwindling and increasing noddy backup options provided by Microsoft." This is exactly what I am finding. I probably should use Windows Easy Transfer as it is more like a file-to-file copy. Now, if I kill this, all of the last 30 hours will be wasted, and I still 20% more to go! And this was meant to be an extra backup! What exactly are beta testers doing for MS these days? Aren't they giving meaningful feedback any more? Is MS just living in a world all by itself? I hate to be a hater...but DAMN! ---- "Anthony Q.
