Office 2010 Standard Key Why is Windows Backup on

[lettsen04517]

Beneath Windows 7 RTM,Office 2010 Download, I can use file duplicate to copy 250GB of files to my external eSata generate in about 1 hour at 72 MB/s.
When I attempt to use Windows Backup,Office 2010 Standard Key, it requires 14 several hours to backup the identical sum of information (i.e. about 5 MB/s).
It looks like Windows seven is attempting to compress each file individually and it is performing alot of Random Disk I/O.
How can I pace up Windows 7 Windows Backup to acquire wherever around approaching the 72 MB/s from a straight file copy?
Are there any superior choices (e.g. in the Registry) that can be changed to improve this horrible overall performance?
Having getting forced from the OS to discontinue the preceding use of reputable Tape backup via NTBackup,Office Professional, this is getting to look like a conspiracy to force users to go and acquire true Backup application through the likes of Semantec instead utilize the rapidly dwindling and increasing noddy backup options supplied by Microsoft.
