Thanks for suggestion yongitz.

I also first decided to go with rsync. But one of senior collegue having trouble with that in past. Because our image server has thousands of listing in image directory and beneath.

So he is saying rsync will first do ls -la in directory and then compare with backup image server in the same directory. So doing this comparison it eats lots of I/O & increases server load rapidly as result of ls -la yields thousands of listings. By the way i didn't try rsync anyhow.

So that is one of the problem i didn't go with rsync.

Are you agree that rysnc creates prolbems in our scenario ?

Is their any other way ?

Or can you let me know the advantages & Disadvantages of rsync ?

Our structure is

root@linux/images } ls -la
root@linux/images } 1/ --> 12/ --> 123 --> having 20,000 listing jpg's
root@linux/images } 2/ --> 21/ --> 211 --> having 25,000 listing jpg's
root@linux/images } 3/ --> 31/ ---> 311 --> having 30,000 listing jpg's
root@linux/images } continue ...
root@linux/images } continue ...

pfsinhdrgen(1)						      General Commands Manual						    pfsinhdrgen(1)

NAME

       pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.

SYNOPSIS

       pfsinhdrgen <sample.hdrgen>

DESCRIPTION

       This  program  reads  files  defined  in  given	hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
       brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.

       The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.

       HDRGEN script file is a plain text file in  which  each	line  contains:  <path_to_an_image>  <inverse_of_exposure_time_in_seconds>  <aper-
       ture_size> <iso_speed> 0

       In  most  cases	it  is	convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
       information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:

       <--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8  100  0  /var/tmp/images/img10.jpg
       76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen

EXAMPLES

       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in sample.hdrgen script.
