Thanx for your answer,

The windows pc the size of backup is not more than 200MB.

This observed in 20% to 25% pc only. Other pc are working on quite acceptable speed.

Again I am taking backup with rsync method.

What should be check ??

Hmm.  So, you're saying that by explicitly stating the directory names
in the included files list, it runs faster?  It might be the
codepage/character set the Windows boxes are installed with differs from
the backup server, maybe?

Out of curiosity... Do these clients have any folders with thousands of
files in them?  Traditionally, FAT32 has horrible performance in these
directories, so much so that copying them can be tens to hundreds of
times slower than the device's capability, due to the file system
overhead of finding the inode corresponding to the filename.  Their long
filename support is pretty nasty and bloated.  From memory, a directory
of mp3's with lots of characters in each name is my worst case, and it
has about 4000 files in it.  It's very slow just to pull up a directory
listing of it.  NTFS is better in this regard, but I'm not going to say
"good".
