Today's NTFS handles fragmentation alot better - in fact,
FAT and FAT32 were really the main file systems that would always get
fragmented. That is not to say NTFS is not immune to the fragmentation that
people may experience, but there are ways around to minimise it even
more.
Depending on the volume itself, and its intention is the
key to keeping fragmentation down. When you format a volume you get the option
of a "cluster" size. But you must be aware of what the volume itself will be
storing. (for example, large files, or millions of small
files).
By default, when formatting, Windows keeps a "default"
setting in place. Choosing a smaller cluster variable will waste less disk space
but likely to cause fragmentation.
Likewise, a larger cluster variable will cause less
fragmentation but waste space. further details can be found in the online help
of Win2k3, XP, 2000, ect !
Not to put my foot in it, but I am sure other systems
suffer, but maybe its a NTFS thing ;-)

It's
NTFS and you're creating and deleting a lot of files on the volume so of
course it will fragment. Either defragment the volume or set the minimum
threshold lower so that more files get deleted when the cleanup process runs
to reduce the fragmentation.

Thanks for the info guys.
It sounds like fragmentation is
just a given when it comes to backing up to disk? I understand that, as
seeing it explained does make sense. I have been looking for some of this
"well documented" information and have come up empty. Searching for
fragmentation on Symantecs site is like a journey through the looking
glass. I will keep looking, but if anyone has any links to a white paper
or something it would be much appreciated.
Also, when you say "set the
minimum threshold lower so that more files get deleted..." This confused
me; I mean, isn't the fragmentation being caused by so many file
creation/deletions? Wouldn't increasing the amount of files being deleted
also increase the fragmentation?
Or did I misread that?
Thanks
again for the info,
T.
