Defrag and NSB

Thread needs solution

In 2012, if I do a defrag (default on Windows 7 is every week), won't that mean that all files will be treated as new? What's the workaround?

Thanks,
John

It will mean that the moved sectors will be treated and changed or "new".

What to do about it? Don't defrag or defrag less often or only defrag jsut before you're going to make a new full backup. Defragging is a tremednously overrated function. IF you do the math on average access times times number of fragments on a given file, you'll get a gross idea of how much time defragging will save when you read/write that file and you'll see how little defragging helps speed things up. Take, e.g., a really hug file with a really large number of fragments -- you'll see that you maybe save a portion of a sec or so on a totla disk read/write that takes minutes. To get this small improvement in disk read/write time, you thrash your disk like crazy running frequent defrags.

Programs like Perfectdisk, one of thenicer defraggers around, imo, actually has built in algorithms to moderate defragging on windows machines to minimze the impact on windows on Restore/Backup function.
