Shell Programming and Scripting

What backup scheme are you using? Is it within the LAN or an offsite backup? If I were you, I would discard my current backup process and go with rysnc. It will automate the process of deleting files deleted from the source machine.

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 ...
